With a national reform agenda that includes all american students and federal legislation barring job discrimination against individuals with disabilities, concerns have mounted about how to accurately assess persons with disabilities. including these individuals in the assessment process often requires the modification of tests and testing procedures. along with these modifications come many complicated issues. this article reviews the literature pertaining to testing accommodations for people with disabilities. we address policy and legal considerations, existing standards, research on current practice, and research on technical concerns. we examine the relatively limited set of empirical studies on accommodations and assessments (many of which were conducted by test publishers) and recommend a significant program of research on testing accommodations for students with disabilities.
