High-Stakes Testing Accommodations: Validity Versus Disabled Rights

Traditionally, measurement specialists have provided testing accommodations for examinees with physical disabilities such as blindness or impaired mobility. Following passage of the Americans with Disabilities Act of 1990, advocates for the disabled have argued that federal law also requires testing accommodations for mental disabilities such as dyslexia and other learning disabilities. Such requested accommodations have included readers, calculators, word processors, and additional time. But these accommodations may affect test validity, requiring measurement specialists to balance the social goal of integrating the disabled against the measurement goal of accurate test score interpretation. Although the courts have provided some guidance regarding testing accommodation requirements for the disabled, they have not yet addressed the issue of where to draw the line on accommodations for mental disabilities. This article explores the measurement problems associated with granting accommodations for mental disabilities, uses existing case law to construct a legal framework for considering such accommodations, arid discusses the advantages and-disadvantages of alternative strategies for handling testing accommodation requests.
