This chapter introduces theory that undergirds the role of testing adaptations in assessment, provides examples of item modifications and testing accommodations, reviews research relevant to each, and introduces a new paradigm that incorporates opportunity to learn (OTL), academic enablers, testing adaptations, and inferences that can be made from…

Lissitz and Samuelsen (2007) propose a new framework for conceptualizing test validity that separates analysis of test properties from analysis of the construct measured. In response, the author of this article reviews fundamental characteristics of test validity, drawing largely from seminal writings as well as from the accepted standards. He…

To facilitate the proper technical use of the test scores obtained from the administration of the tests, the curricular and psychometric characteristics of the tests are described in a series of technical manuals. This manual, the seventh in the series, contains a description of the characteristics of the North Carolina Test of Chemistry. The test…

Fifty education majors in two sections responded to an Attitudes toward Mathematics and Its Teaching (ATMAT) scale. Results with two psychometric models, classical true-score theory and the one-parameter Rasch model, supported the ATMAT's reliability, content and construct validity, and invariance over three time points.
