Testing Accommodations Research and Decision Making: The Case of “Good” Scores Being Highly Valued but Difficult to Achieve for All Students

Abstract

The authors review both (a) definitional and legal issues associated with testing accommodations and (b) validity issues that confront educators who must make decisions about the use and likely effects of testing accommodations, and they summarize the results of 4 experimental studies they have conducted that examine the statistical effects of accommodations on test scores of students with and without disabilities.
