The study investigated the amount of extended time (ET) used by postsecondary students with learning disabilities, attention-deficit/hyperactivity disorder (ADHD), and psychological disorders granted a 50% ET accommodation (i.e., time and one-half). Extended time used was evaluated by disability type, including comorbid presentations, and year in school. The sample was composed of 2,227 undergraduate course tests taken with ET. ADHD was the most common disability, and the majority of tests (75%) were taken by upperclassmen. The average amount of time used on tests taken with ET was well below the amount granted, and no pattern emerged to suggest a connection between disability type and amount of time used. Further, tests taken by individuals with multiple disabilities generally did not require greater amounts of ET than tests taken by individuals with single disabilities. Implications and recommendations regarding disability service access and ET as an accommodation are discussed.
