Promoting workforce excellence: formation and relevance of vocational identity for vocational educational training

Abstract

Vocational learning comprises more than factual knowledge and procedures; the development of a vocational identity is a key aspect and outcome of vocational education provisions and assumed to play an integral role in how students learn and perform. Despite the salience of vocational identity however, the processes that contribute to its formation are far from fully understood. It is unclear whether and which elements of vocational education and training provision shape this process and if and to what degree forms of identity really support the actual vocational performance of a vocational learner. This study seeks to provide deeper understanding of the circumstances that enable different forms of identity to develop and how they direct learning and workplace effort. Using structural equation modeling with data from 504 vocational learners and correlation analysis with data from 187 industrial apprentices, this article proposes a model to account for key influences and the impacts of vocational identity formation for the commercial sector. The results indicate that vocational identity mediates and is closely aligned to the development of vocational engagement and competence. A free career choice and the provision of maximal functional integration into operating processes at the workplace are key factors underlying identity formation.

Background

The purposes of vocational education and training (VET) go beyond developing the technical capacities required to perform an occupation effectively or securing students’ employment (Baethge et al. [2009]; Renold [2009]); they extend to the formation of students’ identity within and attachment to an occupation, as well as their integration into society through that identity (Baethge and Arends [2009]; Drexel [2005]). A characteristic feature of the German initial vocational training system, for example, is that those undertaking apprenticeships develop strong occupational ties and form an identity associated with that occupation, rather than loyalties to a specific company or employer (Haasler [2007]; Rauner [2007]). Skilled workers’ vocational identity is a crucial component of the German workforce, central to its ability to remain successful in an era of unprecedented global competition, because of its effects on vocational capacities, skill performance, and quality (Rauner [1999]; Skorikov and Vondracek [2007]). Without vocational identities, workers’ abilities to plan, execute, and monitor their work activities autonomously would be far less likely. In turn, vocational identity guides workers’ practices during the course of completing complex, demanding tasks, and it offers a sustainable source of intrinsic motivation that directs and secures individual engagement with the vocation (Rauner [1999]). Thus, for both institutional and personal purposes, developing strong vocational identities is an implicit goal of German vocational education; in Switzerland, it is even explicitly included in the stated learning outcomes for the vocational education system (§50 BBG [2002]).

Despite the salience of workplace and vocational identity however, the processes that contribute to its formation are far from fully understood. It is unclear whether and which elements of VET provision shape learners’ identities and even more unclear whether the desired effects of a strong identity in terms of an enhanced vocational performance actually materialize. To shed light on how these factors and associations contribute to vocational performance, we need an integrative approach to investigate both contextual and psychological factors. Such an inquiry would contribute to deeper understanding of the circumstances that enable different forms of identity to develop and how they affect both learning and workplace effort.

To this end, we first outline the theoretical concepts vocational identity and workplace identity. We then present a background model and a conceptual model, informed by a thorough review of the literature and accounting for major hypotheses about the genesis and effects of vocational identity. Regarding the elements of VET that shape these concepts, our literature review focuses on (1) the effect of a dual versus school-based VET, (2) integration at the workplace, and (3) free career choice; for the effects and alignments of vocational identity, we focus on (4) workplace effort and (5) vocational competence as prerequisites for effectual vocational performance. We then show that associations across occupational environments, together with students’ or apprentices’ vocational performance, are mediated by fundamental motivational traits associated with vocational and workplace identities. Figure 1 presents our conceptual model graphically.

Conceptual model.

As a result, we provide a clearer understanding of how vocational learners are motivated to develop such associations. We ask weather government's and employer’s expectations of the German dual VET are realistic and how these expectations can be realized. Accordingly, we consider how students learn (Pellegrino et al. [2001]; Shavelson and Ruiz-Primo [2005]), how they exercise agency in participating in and learning through work, and on what bases and for what purposes they exercise this agency.

Theoretical conception of vocational identity

To understand the mechanisms that lead to the formation of vocational identity, we must clarify what is formed and how to measure that formation. Next, we define the terms “vocation” and “identity” to provide a clearer picture of our conception of vocational identity.

Billett ([2011]) distinguishes an “occupation,” which comprises social facts, from the personal elements that individuals come to identify with and assent to as their “vocation.” Thus, we acknowledge both occupations and something else that describes people’s interests or “calling.” In the second sense, vocations might be specified as those activities to which people are drawn (Estola et al. [2003]) or “called” (e.g., Dror [1993]), which provide lifelong fulfillment through their exercise (Hansen [1994]). Separating these two usages is critical to understanding occupational identity (i.e., vocation), in that they imply distinct goals for vocational education and separate measures.

The first term, occupation, refers to institutional, normative, and discourse practices associated with individual identities. Occupations offer examples, which are ordered and valued in particular ways, starting with their origins in historical and social forms (Billett [2011]). Accordingly, identifiable societal expectations and factors are associated with people with an occupation, whether as an auto mechanic, nurse, accountant, or industrial clerk. In contemporary terms, the notion of vocation as occupation suggests that VET should be highly responsive to industry expectations, existing standards, and employers’ needs, often supported by government interests and economic imperatives. This influence becomes particularly salient when there are either national skill shortages or high levels of unemployment, particularly youth unemployment (Aldrich [1994]; Anderson [1998]; Butler [2000]; Kantor [1986]; Renold [2009]). During these periods, vocational education is primarily a means to provide effective preparation and a smooth transition for students into the occupational practices needed in society. Governments’ typical definition of vocational education thus focuses primarily on developing the capacities needed for particular forms of work (i.e., occupations) in ways that meet societal needs (i.e., demand for skilled labor). Its purposes, forms, and key endorsements appear within and are products of society, that is, institutional facts (Searle [1995]).

The second term, vocations, is defined as the individual worker’s journey, calling, or personal trajectory (Dewey [1916]). The essentially personal phenomenon energizes and directs a person’s individual’s intentions, activities, and interactions (Estola et al. [2003]), even as they continue to be shaped by external factors (e.g., societal standing of the occupation, gendered associations). This view also accounts for the process of learning, which is a person-dependent process. From this perspective, VET functions to secure personal goals and development pathways, thus assisting students in engaging in learning that reflects their aspirations and enables them to realize their full potential.

By combining these views, we propose for this study that vocations are personally directed but also socially derived practices that reflect a person’s enduring aspirations and interests. They are usually manifested in culturally and historically derived activities that offer value for both the individual and the community (Billett [2011]).

Social science has different conceptualizations of identity, focusing on (1) a social identity conceptualization designating a person’s position in a social system and (2) a personal identity conceptualization denoting aspects of individual experience rooted in interactions (Côté and Levine [2002]). At the level of social identity, the individual is most influenced by cultural factors and social roles, experiencing varying degrees of pressure to fit into an available identity that can be characterized mainly as a vocational habitus (e.g., Bourdieu [1990]). This concept corresponds to our understanding of the term “occupation.” In contrast, at the level of personal identity, individuals find a fit between their perception of the social world and their own personality (potentials, interests, and desires, often referred to as “aspirations”). A personal identity is therefore affected by social influencing factors, but this relation is pivotally designated by individual personality and how people perceive such external influences (Mead [1934]). This identity definition corresponds to our understanding of “vocations.” Accordingly, we define “vocational identity” as how people negotiate and align their personality with an occupation’s norms and practices or, more precisely, as the fit between an individual’s perception of the occupational world and his or her self-perception.

We further propose, in line with Marsh and Shavelson ([1985]), that the analysis of a person’s identity in regard to a specific area or domain (e.g., toward a vocation) is more fruitful than a global identity conception. We acknowledge that the relative salience of identity domains may vary across cultures and socioeconomic contexts but note that several studies confirm that vocational identity development is a priority in adolescence (Kroger [1993]; Skorikov and Vondracek [1998], Solomontos-Kountouri and Hurry [2008]). In the domain of vocational identity, theoretical and empirical research streams have generally confirmed that two subdomains of vocational identity exist: one referring to the actual vocation in a broad sense and one referring to a person’s workplace (also referred to as “organizational identity”; e.g., Cohen [1991]; Lee et al. [2000]; Wallace [1993]). We refer to both conceptions for our research endeavor.

We operationalized the first concept of vocational identity according to our theoretical definition: the fit between a person’s perception of the social structures of an occupational world and that person’s perception of his or her own personality. To measure this concept, we asked students about the fit between their chosen vocation and their personality (e.g. “My vocation fits me,” “My vocation is an integral part of who I am,” “I am proud of my vocation”). Workplace identity analogously refers to the perceived fit between a person’s sense of self and the workplace’s norms and practices. We accordingly asked apprentices if, for example, they feel like a part of their company, if they draw satisfaction from working for it, if they consider their company as fitting to them, and if they are proud to be a part of their company.

Hypotheses: Predictors and impacts of vocational identity

Our general framework (shown in Figure 2) for analyzing our theoretical conception of vocational identity is based on House’s ([1977]) personality and social structure perspective (PSSP) and its proposed levels of personality, interaction, and social structure. Lempert ([2009]) transfers the PSSP model to a theoretical model of the formation of vocational learning, identifying vocational identity as a major aspect of vocational learning. The person interacts with the social structures of the occupational environment (“interaction” here refers to the person’s contact and communication with his or her surroundings, comprising several cognitive operations). This interaction is crucially influenced by the person’s personality (including cognitive structures), which then influences his or her perception and interpretation of vocational experiences, resulting in differentiated processing of experiences and ultimately reactions (impulsive) or actions (considerate).

Figure 2

Theoretical framework: levels and operations determining the genesis and effects of vocational identity according to Lempert ([2009]).

According to this model, we regard the process of identity formation as a function of both external (social) and internal (agentic) components, suggesting that both sociological and psychological perspectives are essential for a comprehensive understanding of this concept (Côté and Levine [2002]; Lempert [2009]). We further assume, in line with this model, that vocational identity affects a person’s actions and reactions at the workplace: it influences the person’s work results and therefore his or her vocational performance (i.e., “performance” defined, in line with Chomsky ([1981]), as the outward production of actual events at the workplace). Performance occurs when there is competence as well as possibility and willingness for demonstration (Achtenhagen [2004]; Boekaerts [2002]).

To identify possible major influences and the effects of vocational identity, we began by designing a conceptual model. Next, we conducted a thorough review of the existing literature in the vocational identity domain. We then formulated five hypotheses and implemented them into one coherent and empirically testable theoretical model (Figure 3). We detail our hypotheses in the following subsections.

Figure 3

Theoretical model.

Vocational identity is fostered better by dual training than by school-based learning

Both blue- and white-collar apprentices in Germany gain work skills through a dual system that comprises both on- and off-the-job components. Off-the-job training is financed by the state, with the aim of developing theoretical knowledge the worker will need in the occupation, in addition to the knowledge gained through a general education. On-the-job preparation entails participation in work activities at a firm, which includes a systematic regimen characterized by adherence to training regulations and interactions with trainers or masters who guide apprentices through the realistic components of the apprenticeship (Ashton and Green [1996]; Kutscha [2000]). Furthermore, apprenticeships tend to be sensitive to business cycles, such that in 2011, only 51% of students participated in the dual system, whereas 20% enrolled in regular vocational schools, and 29% prepared for regular vocational training in a so-called transitional system,^a also organized by vocational schools (BMBF [2012]). Because of this trend, we compared the consequences of participating in either dual or school-based training, including the implications for the formation of vocational identity. Kirpal ([2006]) posits that more positive outcomes derive from dual vocational preparation than from a solely school-based preparation for identity formation; we draw on this proposition and predict that continuous learning at the workplace, such as the learning gained in a dual training, positively influences identity value. We tested this hypothesis using a dummy variable indicating dual or solely school-based training.

Workplace identity is determined by workplace integration

We define “workplace integration” as the functional integration of apprentices into operating working processes. Individual workplaces feature distinct practice requirements, due to their unique location, clients/customers, services offered, workplace culture, norms, history, and employees. Thus, various firms have unique ways of working and desired outcomes, even if they engage in similar occupations (Billett [2006]). Apprentices’ workplace experiences, including activities and interactions, influence what they learn, mediated by social interactions with other employees. People who have been invited to participate in work activities and integrated into the work process thus may come to identify more with their workplace. Qualitative research affirms the importance of work participation for shaping identities and competencies (Corsten and Lempert [1992]; Hartigan-Rogers et al. [2007]; Henderson et al. [2007]). Newton et al. ([2009]) find that when workplace environments welcome and support novice nurses, providing them with opportunities for active participation in the work process rather than just observational roles, they contribute richly to learning. Such experiences also should support the formation of workplace identity. Thus, whereas our first hypothesis compared the vocational identity of apprentices undergoing dual vocational versus school-based training, our second hypothesis relates solely to dual vocational apprentices, who have opportunities to experience real-life work, to predict how these experiences influence their workplace identity. To address this issue, we asked apprentices if they felt integrated into all operating processes of their back office.

Vocational identity is enhanced by free career choice

A vocation in our definition implies a calling; therefore, the ability to choose a particular occupation is critical. In line with Bühler ([2007]) and Heinemannet al. ([2009]), we suggest that free vocational choice not only is desirable for its own sake but also can shape the formation of the person’s vocational identity. We define “free career choice” as the degree to which the choice of a person for his or her preferred vocation was a voluntary one. Involuntary career choices may be the result of, for example, monetary restrictions, social pressure to choose a certain vocation, or certain forms of discrimination constituting barriers for a person to choose a desired vocation (Lent et al. [2000]). To assess this influence, we used the item, “My vocation was my preferred vocation of choice,” introduced by Heinemannet al. ([2009], p. 10). However, we acknowledge that vocational trajectories also may arise through participation in activities that were not initially enacted or identified by workers as vocational for them but were locally and socially convenient (Billett [2011]). For example, Somerville ([2006]) finds among elder care workers in Australia that though they did not originally intend to pursue this vocation, they became increasingly engaged with their work and developed a strong vocational identity over time.

Workplace effort within VETs is mediated by vocational identity

Several studies have examined the relationship between forms of vocational and workplace identity. Wallace ([1993]) cites a corrected average correlation of .45 between the two concepts, and with a meta-analysis, Lee et al. ([2000]) specify a similar corrected correlation of .45 between occupational commitment and organizational commitment (which we refer to as “vocational identity” and “workplace identity”) across 49 samples. However, the causality between these variables remains somewhat unclear; they may even be bidirectional. According to Peiperl and Baruch ([1997]), in a post–corporate career realm, vocational identity gains potency and serves as a source or predictor of workplace identity. They argue that people decide to become members of an occupation before being employed by a particular employer. Aranya et al. ([1981]) propose that professional affiliation is both separate from and a precedent of an affiliation with a particular workplace. Because vocational identification develops prior to workplace identity, when professionals leave a job for another employer, they should sustain their professional affiliation. This latter assertion is uncontroversial; the former is open to question. In the German VET setting, apprentices in a dual system likely develop their vocational identity while working for a company. For apprentices, after they begin working, their workplace likely shapes their vocational identity as they experience and perform work associated with the selected vocation, which also has implications for their vocational identity (Hypothesis 4).

Vocational learning theory further posits that different forms of identity related to the vocation or the company increase workplace effort. We define “workplace effort” as the activities and intentional efforts that students/apprentices direct toward work performed within the training company. An increasing body of research focuses on vocational learning as a component of individual efforts to contribute to work-related activities and interactions (e.g., Hodkinson and Hodkinson [2004]). However, the relation between workplace identity and workplace effort seemingly has decreased in recent decades (Baruch and Cohen [2007]; Cohen [1991]; Randall [1990]). In the modern, individual-based labor market, companies offer weaker generators of identity or sources of personal commitment (Baruch and Cohen [2007]). Therefore, we predict that vocational identity mediates the association between workplace identity and workplace effort, such that vocational identification takes the dominant role (Hypothesis 5). To test this prediction in our statistical analysis, we test vocational identity as a mediator between workplace identity and workplace effort. To operationalize our definition of workplace effort, we asked the apprentices how much effort they expend when contributing to their company’s success and how much they try to influence decisions and improve actions to ensure the quality or efficiency of their work.

Vocational identity is closely related to vocational competence

A successful vocational performance requires not only vocational volition but also cognitive ability. The question here is whether vocational identity is also positively aligned with vocational competence. Vocational learning theory posits that forms of identity shape the quality of learning activities. For example, Baethge and Baethge-Kinsky ([1998]) and Rauner ([2007]) depict vocational development as a coherent process of identity and competence development occurring while becoming member of a vocational community. Both studies assume bidirectionality of this relationship. Also, in our background model, vocational competence constitutes another cognitive trait on the personality level and therefore cannot be regarded as unidirectional. Accordingly, we aim to empirically investigate the strength of the interactive relation between the two concepts. We define “competence” in line with Hartig, Klieme and Leutner ([2008]) as a cognitive disposition that is learnable and focused on a certain field of action (domain-specific). In our research context, the field of action or domain is localized in the activities of commercial vocations. We assume that competence, as a cognitive disposition, influences the solution of domain-specific situations and tasks, so it is therefore reasonable to deduce back from the solving of authentic situations to cognitive structures through adequate item design and psychometric procedures (e.g., Wilson [2008]; Shavelson [2008]). Because measurement of vocational competencies includes both knowledge and action, the tasks implemented within the competence test focus on at least three competence levels, all aiming at the measurement of vocational expertise (see Greeno et al. [1984]):

• 1. Conceptual competence corresponds to factual knowledge that can be transmitted into action schemata.

• 2. Procedural competence subsumes the application of knowledge, that is, how to operate with facts, structures, knowledge nets, and their corresponding elements.

• 3. Interpretative competence focuses on an interpretation of results and on decision processes.

Together, these competence levels refer to successfully completed, occupation-specific tasks. We implemented this operationalization with 36 test items to determine empirically the relation between vocational identity and vocational competence. Our data set (N = 187) included industrial apprentices who were assessed in March 2013 at four German vocational schools. Sample tasks of our instrument can be found in the Additional file 1.

In summary, our literature review identified several predictors of vocational and workplace identity: (1) a dual versus school-based VET, (2) workplace integration, and (3) a free career choice, as well as two effects: (4) willingness to perform and (5) vocational competence as prerequisites for vocational performance. Our theoretical design further predicts that associations between the characteristics of occupational environments and vocational performance are mediated by the more fundamental motivational qualities of learners’ vocational and workplace identities (see Figure 3).

Study design

Research questions

The theoretical outline, according to our background model (Lempert [2009]), suggests that vocational identity mediates the effects of occupational environments on vocational performance and therefore potentially provides a rich characterization of how apprentices perceive and act. With the present study, we aim to gain insight into the relevant mechanisms. The focal research questions are as follows:

• (1) How structurally valid and reliable are the derived measurements of our theoretically outlined definitions?

• (2) How do the characteristics of vocational training, specifically, (a) dual versus school-based training, (b) integration in workplaces, and (c) a free career choice, predict vocational and workplace identity?

• (3) How do vocational and workplace identities mediate the relationship of the predictive variables with workplace effort?

• (4) Is there a detectable relation between vocational identity and vocational competence? More precisely, do apprentices who identify to a greater extent with their occupation or company also achieve higher scores in objective competence tests of their vocational expertise?

Sample characteristics

The data, gathered in July 2012, comprise a sample of N = 504 learners in the middle of their vocational education as industrial clerks. To compare apprentices working in a dual system against students engaged in school-based training, 290 of the participants were undergoing a dual and 214 a school-based VET. In total, 55% of the survey participants were women, and 47% of the students had a migrational background. However, neither gender nor migrational background correlated with the variables featured in our analysis, so we did not control for them. To research the relation between vocational identity and vocational competence, we conducted objective competence tests empirically of N = 187 industrial apprentices in March 2013 at four vocational schools (Munich, Hanover, Bielefeld, and Paderborn). 47 of the apprentices were tested after 1.5 years and 140 apprentices after 2.5 years of their vocational training. The test took 125 minutes, including the test instruction (10 minutes) and completion of the identity survey (10 minutes).

Instruments

The paper-and-pencil survey consisted of two sections. First, 11 items referred to socioeconomic and biographical information. Second, 14 items measured the indirectly observable constructs of vocational identity, workplace identity, and workplace effort. Our scale development for these items was informed by Blau ([1988]), Carson and Bedeian ([1994]), and Heinemann and Rauner ([2008]). Participants were instructed to give answers that reflected their personal perceptions, using five-point Likert scales, from 1 = “I do not agree” to 5 = “I totally agree.” Thus, higher scores indicated a higher value for the related construct. The competence test comprised 36 items depicting knowledge and ability in the area of business and commerce. The item responses were scaled using a correction scheme (0 = “incorrect or no solution,” 1 = “partial solution,” and 2 = “correct solution”). The responses were then combined into one factor value for each participant. The respondents participated voluntarily during both data collections, through an agreement with their teachers and the schools’ executive boards.

Method

To begin our data analysis, we evaluated the measurement instrument. An exploratory factor analysis validated the survey’s factorial structure. The data seemed appropriate for factor analyses (KMO = .89; Bartlett test = .00), so we conducted an analysis with the Kaiser criterion and a parallel assessment (Horn [1965]) to identify the number of latent constructs in the database. Structural equation modeling (SEM) in AMOS served to align the measurement models with the hypothesized relations of the study constructs. Missing data were addressed through full-information maximum likelihood estimation (FIML); several simulation investigations affirm that FIML outperforms most other common methods of handling missing data (Baraldi and Enders [2010]; Enders and Bandalos [2001]). To address the research questions, we fit baseline models of the direct effects of the four independent variables on the latent factor constructs. After establishing these direct relationships, we introduced vocational identity and workplace identity as mediators of vocational performance and tested the mediating effects. Specifically, we estimated indirect effects with delta method standard errors to confirm the mediation (MacKinnon et al. [2002]; Sobel [1982]). To test Hypothesis 6, we built a mere factor score for the competence test and conducted a bivariate correlation analysis with the constructs in our identity survey.

Results

Measurement model

As a result of an analysis with the Kaiser criterion and a parallel assessment (Horn [1965]), the survey items indicated a three-factor solution. Figure 4 presents the results graphically.

Figure 4

Factor extraction.

The empirical factor analysis of our survey instrument led to the theoretically assumed structure in which vocational identity, workplace identity, and workplace effort are empirically separate concepts. The three concepts explain 62% of the total variance and affirm strong internal consistency (Cronbach’s αs: factor 1 = .83; factor 2 = .90; factor 3 = .71). This three-dimensional structure also received confirmation in a confirmatory factor analysis in AMOS; the three-factor measurement model fit the data significantly better (.000) than a two- or one-factor model.^b Table 1 presents all the questions from the measurement instrument and contains the respective factor coefficients and R-square values.

Table 1 Empirical fit of items measuring vocational identity

The formulated items and derived instrument thus can measure vocational identity appropriately, in terms of factorial validity and reliability. All variables had low to moderate correlations (.07 to .57), suggesting little multicollinearity. Therefore, we conclude that the instrument is applicable for testing the hypotheses regarding the influences on and effects of vocational identity. Table 2 provides the correlations among the generated factors.

Table 2 Means, standard deviations, and intercorrelations among all relevant variables

Directly fitted path model

The standardized path coefficients for the directly fitted model are depicted in Figure 5. Integration at the workplace was positively associated with workplace identity (r = .42), workplace effort (r = .41), and, to a lesser extent, vocational identity (r = .28). From a biographical perspective, students who decided voluntarily on their vocation were more likely to develop workplace (.34) and vocational (.52) identity and to perform effortfully (.29). In summary, the model accounts for 31% of the variance in workplace effort, 37% in workplace identity, and 38% of the variance in vocational identity. However, the overall model fit is poor (χ²/df = 9.999, p = .000; comparative fit index [CFI] = .882; root mean square error of approximation [RMSEA] = .134).

Mediated path model

Modeling vocational identity as a mediator between workplace identity and workplace effort significantly improved the overall model fit (χ²/df = 1.300, p = .272; CFI = .998; RMSEA = .024). Regarding causality, we determined that the model predicting an effect of workplace identity on vocational identity fit the data significantly better than a model with the opposite effect (.000), in support of Hypothesis 4^c. We present the standardized path coefficients for the mediated model in Figure 6. We excluded the significant direct effects between the independent variables and vocational engagement from the model for clarity; Table 3 presents these values.

Figure 6

Mediated path model.

Table 3 Standardized direct, indirect, and total effects for mediated relations

Table 4 Correlation analysis of the relation between vocational identity and vocational competence

The group variable, indicating dual versus solely school-based VET, had a significant though small effect on vocational identity (r = .09). The effect of workplace identity on workplace effort was partially mediated by vocational identity (r = .10). Although the direct effect of workplace identity on vocational identity was strong (.49), its direct effect on workplace effort decreased and became quite small (r = .08) when we allowed the mediation through vocational identity. The effect of free career choice on workplace effort was partially mediated by vocational identity and workplace identity (r = .14); it also had a direct effect on workplace effort (r = .16), workplace identity (r = .38), and vocational identity (r = .35). However, the effect of workplace integration on vocational identity was not significantly mediated by workplace identity (r = .08). Instead, workplace integration directly increased both workplace identity (r = .46) and workplace effort (r = .37). Including the mediating variables added 8%, 12%, and 7% to the explained variance, yielding overall explanations of 39%, 50%, and 44% of the variance of vocational identity, workplace identity, and workplace effort, respectively.

For the relation between vocational identity and the vocational competence of the apprentices, we found an effect of r = .25 in support of Hypothesis 6 (Table 4). Vocational identity further correlates with the average grade obtained at the vocational school (r = .15) and the apprentices’ self-rating of their vocational competence (r = .24). (We measured this self-rating on a six-point scale, in line with the German grading system.) Workplace identity correlates to a lesser extent with the competence tests (r = .14) and the apprentices’ self-rating of their vocational competence (r = .16). The competence tests correlate fairly well with the average grade given by the vocational school teachers (r = .40) and with the apprentices’ self-rating of their vocational competence (r = .33), suggesting high retrograde and concurrent validity of the competence measure.

Discussion

Our study of vocational identity as a personal concept, arising through interactions between the person and the mode of VET, features tests of six theoretical hypotheses about the genesis and effects of vocational identity. We discuss the results in the following subsections.

Hypothesis 1

In our quantitative, empirical model, we first predict that vocational identity can be fostered more effectively through continuous workplace learning experiences, which can be implemented with dual VET (Kirpal [2006]). We find only a minor, albeit stable, effect in support of this prediction: Students who spend half their study time in workplace environments tend to identify slightly more strongly with their occupation than students who study only in a school setting. However, one might expect a higher group effect; theoretically, students without workplace experience cannot build a vocational identity, because they have never engaged in the occupational practice or with its practitioners. Therefore, we suggest that the issue of whether scholastic or dual apprentices identify more strongly with the occupation might be not the right question: 27% of scholastic learners stated in our context survey that they had already gathered practical experience in the business and commerce sector through pertinent internships. This finding indicates that our dummy variable of a dual versus solely school-based training does not adequately capture the amount of practical training a learner underwent. Comparing learners with practical experience (scholastic learners with prior pertinent internships or dual apprentices with continuous working experience) versus learners with no practical experience generates an effect of .19. Therefore, the amount of practical training might be a more precise predictor of vocational identity than dual versus solely school-based training.

Hypothesis 2

Integrating vocational apprentices into organizational work processes strongly increases apprentices’ workplace identity and has a direct effect on their workplace effort. Positive cooperation with apprentices requires their effective engagement in work groups, in support of the concept of enhanced participatory practices and enculturation (Lave and Wenger [1991]). Vocational learning is a situated activity that takes place through a process of engagement in the sociocultural practices of the workplace. Chan ([2011]) similarly describes how bakers progress in their vocational identity, such that they first sense belonging to a particular bakery and demonstrate competence before they go on to identify as a baker. The first step is contingent on the degree to which they are accepted, recognized, and granted discretion as an apprentice in the workplace where they apprenticed.

Hypothesis 3

We proposed and found a strong, significant influence of free career choice on both vocational identity and workplace identity. In addition, free career choice appeared to have a direct impact on workplace effort. Students voluntarily deciding on their vocational training identify more strongly with and engage more effortfully in their selected occupation. This finding is consistent with Heinemann et al.’s ([2009]) recognition of a positive correlation between vocational identity and free career choice (r = .27) across 23 VET programs. We thus confirm Hypothesis 3.

Hypotheses 4 and 5

For Hypothesis 4, we tested the causal relation between workplace and vocational identity. On the basis of theoretical considerations, we predicted an influence of workplace identity on vocational identity; this direction was empirically confirmed, such that this causal relation appears more likely among young apprentices. However, for advanced workers at later stages of their careers, or for those starting in a new company, the direction of the causal effect may switch, because they already have acquired a distinct, stable vocational identity that can shape the development of their new workplace identity when they move to a new work environment. The empirical results related to Hypothesis 5 suggest that workplace identity is not as prominent a source of workplace effort as vocational identity. Instead, much of the total influence of workplace identity on workplace effort is mediated by the more general concept of vocational identity.

Hypotheses 6

Regarding Hypothesis 6, the theoretically postulated alignment between vocational identity and vocational competence is upheld. Vocational identity correlates fairly well with our developed competence tests, as well as with grades given by vocational teachers and with apprentices’ self-rated vocational competence.

In summary, two conditions seem required to trigger identity and excellence. First, apprentices must be granted practical experience; during that experience, they must be welcomed and invited to participate in all operating work processes. Second, the apprentices themselves must voluntarily participate to be able to accept this invitation and decide to engage. The effects of the influencing factors on vocational performance are mediated by a personal identity conception (Allan [2005]; Billett and Pavolva [2005]; Etelpäpelto [2008]; Fenwick [2004]; Somerville and Abrahamsson [2003]).

Conclusions and limitations

Our results highlight that several VET characteristics exert important influences on vocational and workplace identity. We find that functional integration at the workplace (Billett [2004]; Chan [2011]; Hartigan-Rogers et al. [2007]; Henderson et al. [2007]; Lave and Wenger [1991]; Newton et al. [2009]), free career choice (Bühler [2007]; Heinemann et al. [2009]), and practical experience (Billett and Somerville [2004]) foster the development of vocational identity. The mediation analyses demonstrate that learners’ vocational and workplace identities, as a form of intrinsic motivation, strengthen the relationships between VET characteristics and the apprentice’s willingness to perform, as Rauner ([1999]) suggests. These conclusions match Billett’s ([2011]) view of workplace affordances and individual bases of engagement as means to understand the duality by which learning arises through work participation. We also show that vocational identity is not only central to vocational volition but also aligned with the development of vocational competence, as Baethge and Baethge-Kinsky ([1998]) and Rauner ([2007]) suggest. We therefore conclude from our analyses that vocational identity constitutes a crucial factor for the development of an excellent workforce, in that it fosters employees’ willingness to perform in work settings and is closely related to vocational competence. We further suggest that vocational instructors have critical roles in terms of creating positive vocational learning environments in schools and workplaces that can optimize learners’ perceptions of their occupations in practice, thereby shaping vocational identity, which then increases competence and willingness to perform. In line with our model results, we outline three points of intervention to strengthen a learner’s vocational identity and thereby optimize VET:

• (1) Grant vocational learners an opportunity to experience actual work. Vocational theory suggests that learners cannot form worthwhile, robust vocational identities without experiencing work and without actively engaging and learning in workplaces. Yet fewer firms seem willing or able to provide apprenticeship experience, which suggests the need for other options. Our results suggest that the amount of practical training is a more stable predictor of vocational identity than dual versus solely school-based training; therefore, we recommend that providing vocational internships can improve learners’ identification with their vocation and potentially overcome differences between scholastic learners and apprentices. At a policy level, governments could cooperate with the private business sector to either train more apprentices or implement more internships as an integral part of vocational school policies.

• (2) Ensure maximum integration at the workplace for apprentices. Apprentices need support as they develop their sense of self as workers, through enhanced participatory practices afforded by workplaces. Our results suggest that by being allowed to participate in all operating processes, they more readily develop vocational identity and apply more workplace effort. Therefore, apprentices need opportunities for active, productive participation in work processes, rather than just taking observational roles or performing isolated, monotonous work. These practices often occur already, but this emphasis should become a central motif for securing the development of vocational identity and capacities.

• (3) Make vocational training consonant with individual workers’ agency. Free career choice is not only desirable for its own sake; it also encourages the development of a highly identified workforce. Our results emphasize the importance of individual interest in and consent to engage fully in the process of occupational preparation. Thus, personal and social efficiency likely can be fostered by a society’s “cultivation of power to join freely and fully in shared or common activities” (Dewey [1916], p. 85). In this respect, vocational education inhabits an important role or responsibility: to assist young people in their efforts to identify the vocation for which they are best suited and to which they are drawn. Policies and practices associated with securing occupation must consider individual agency if the goal is to achieve high engagement and effective learning outcomes.

We note several shortcomings in our study approach. The measurement of vocational identity relies on self-reports to assess students’ identity concepts and work effort. This approach raises important validity concerns, in that students could offer what they perceive to be socially desirable answers. Moreover, the self-reports between the scholastic learners and dual apprentices might be biased by selection effects not captured within our data, as the scholastic system usually comprises young people who did not succeed in entering a regular training system due to a lower class rank in prior schooling and/or poor grades. If these variables influence the fostering of vocational identity, the effect we found might deviate from our results. Another issue resides in our objective competence test for testing Hypothesis 6 (written examination). The items are designed to capture knowledge and capability regarding the expertise of the apprentices. However, they do not capture other relevant facets such as social competence, which is a key factor in handling social interaction processes. We checked our competence tests for retrograde and concurrent validity but not for prognostic validity. Further research should investigate if the measured ability, in the sense of a disposition for expertise, also predicts the actual performance of the apprentices observed at the workplace, as captured through expert evaluations for example. Finally, with regard to the relation between vocational identity and vocational competence, we assumed a mutually reinforcing relation, in line with Baethge and Baethge-Kinsky ([1998]) and Rauner ([2007]). However, there is no clear theoretical rationale of antecedents and consequences regarding this relationship. Longitudinal research is needed to address this question empirically. Therefore, research endeavors should apply the developed identity instrument over the duration of vocational training, combined with competence tests to explicitly test causalities.

Instead, it encompasses various training, education, and labor market schemes provided by governmental bodies to engage young people who did not enter a regular training system (Baethge et al.
