Introduction and Concepts
This chapter provides a general overview of equating and briefly considers important concepts. The concept of equating is described, as is why it is needed, and how to distinguish it from other related processes. Equating properties and designs are considered in detail, because these concepts provide the organizing themes for addressing the statistical methods treated in subsequent chapters. Some issues in evaluating equating are also considered. The chapter concludes with a preview of subsequent chapters.
