Test-takers with disabilities access academic accommodations on standardized college admissions tests under the auspices of the Americans With Disabilities Act (ADA; 2008) and Section 504 of the Rehabilitation Act (1973). Also under these laws, testing agencies request documentation to verify a test-taker's disability status and need for accommodations to equally access an examination (Banerjee & Shaw, 2007). Historically, relevant laws, regulations, and guidance have provided little information regarding the content or scope of the documentation allowed to be requested, leading to variability in documentation policies across testing agencies (Banerjee & Shaw, 2007). More recently, technical assistance provided by the U.S. Department of Justice (2015) has provided increased guidance regarding what constitutes sufficient documentation, as well as what might constitute overly burdensome requests. Some of the guidance has been controversial (Lovett, 2014). This has particularly been the case for the documentation of learning disabilities (LDs) and Attention-Deficit/Hyperactivity Disorder (ADHD), hidden disabilities that account for the majority of accommodation requests (U.S. Government Accountability Office [GAO], 2011). Given these developments, the current study sought to (a) investigate LD and ADHD disability documentation guidelines across testing agencies and (b) evaluate the guidelines within the context of the new DOJ technical assistance. Applicable Law The ADA (2008) and its Title III Regulations (2010) prevent discrimination during admissions tests. To be eligible for protections, LD and/or ADHD must represent a mental impairment that substantially limits one or more major life activities relative to most people in the general population. For qualifying test-takers, testing agencies must ensure that examinations are administered in an accessible manner.
