ADHD is the most common psychiatric condition of childhood, with prevalence estimated at 1 in 11 American youth (Pastor et al., 2015). Students with ADHD present an enormous concern for educational policy-makers, as these students require $4,700 more to educate, on average, than their typically developing peers (Robb et al., 2011), yet they still tend to have poorer educational outcomes (Barkley, 2006; Fletcher & Wolfe, 2008). This begs the question, “Is our support of students with ADHD academically really working?”

There are a wide variety of reasons why students with ADHD may underperform relative to their nondisabled peers, and many ways of supporting these students in the classroom. Supports commonly offered to students with ADHD, often via an Individualized Education Program (IEP) or Section 504 Plan, include testing accommodations, which are adjustments to testing conditions that are designed to reduce the negative impact of a student’s disability on his or her performance. A study that was recently published by researchers at the Kennedy Krieger Institute in Learning Disabilities: A Multidisciplinary Journal (LDMJ;, an official publication of the Learning Disabilities Association of America (LDA;, offers some insight into whether testing accommodations really work for students with ADHD.

The study, “Academic Testing Accommodations for ADHD: Do They Help?” evaluated the effectiveness of testing accommodations for elementary and middle school students with ADHD, many of whom had co-occurring learning difficulties in reading and/or math. Our team at Kennedy Krieger investigated 5 specific testing accommodations: extended time, frequent breaks, a reduced distraction environment, oral presentation of written information, and use of a calculator. We compared a group of students who had access to these accommodations per their IEP or 504 Plan to a similar group of students who did not in terms of their scores on standardized reading and math tests. None of the 5 accommodations under investigation in this study were associated with better reading or math performance, taking into account grade level and co-occurring learning difficulties.

While these findings may suggest that these accommodations are not effective for students with ADHD, one caveat of the study needs to be considered: it is not clear whether the students who had access to accommodations actually took advantage of them during the testing. Thus, it is also possible that students with ADHD have not been taught to use accommodations strategically and have not been given sufficient opportunity to practice using them, therefore they are not able to utilize them effectively. Either way, the status quo regarding academic testing accommodations for students with ADHD does not seem to be working. While more research must be done to determine why students with ADHD are not benefitting from testing accommodations, this study’s findings should help to start the necessary conversations among education researchers and policymakers.
