School-Related Inequity Factors

This chapter focuses on investigating the impact of school-related inequity factors based on the TIMSS 2003 Principal Questionnaire and TIMSS 2003 grade eight math assessment data. In this chapter, the school-related factors measure principals’ perceptions of selected school and classroom practices. The dependent variable is the The Average Plausible Score for the School (APSS) in as much as they can be derived from TIMSS 2003 Principal Questionnaire. Since the original TIMSS school file did not include the mean math score of the students in the same teacher, a linkage program was developed to assign for each school principal the mean math score of students in that school. The (APSS) was computed to be the mean Average of the Mathematics Plausible Score (AMPS) for the students in the sample, who are in the same school (see Chapter 7). In this chapter, A school-related inequity factor is defined to be a school-related factor that accounts for a significant percentage of the between-school variance (students in the same school).
