Efficacy of Extended Time on Exams for College Students With ADHD: A Randomized Crossover Trial Protocol

This randomized controlled trial investigates whether extended test time (25% and 50% extra) genuinely improves exam performance for college students with ADHD, addressing a lack of empirical evidence despite widespread use of this accommodation. As of March 2026, 103 participants have been enrolled and are completing versions of a high school exam under different time conditions to evaluate efficacy and optimal dosage.
