Shepard, L. A. (1993). Evaluating test validity. Review of Research in Education, 19, 405-450. Washington, DC: AERA.
The purpose of this chapter is to trace the evolution and potential future directions of test validity. Shepard addresses topics such as how the definition of validity and measurement has changed over time, and common understandings about the evaluation of test validity. She also offers a model for evaluating test validity based on the work of Samuel Messick (1989). Shepard discusses the discrepancies between theory and practice, and presents real validity cases examining the Scholastic Aptitude Test (SAT), the General Aptitude Test Battery (GATB), and other tests used for placement decisions in elementary school.
