How is extra time justified for students with learning disabilities?
Other students could improve test scores if they were allowed additional time as well. Various factors account for the need for extra time on tests for students with learning disabilities. These include: a) speed of processing; b) visual perceptual deficits; c) difficulty with mechanics of syntax, spelling and punctuation; and d) reading comprehension deficits. Research (at UC Berkeley, 1991 and the University of Toronto, 1993) on the effects of extended time on exams has shown dramatic improvements for students with learning disabilities, but only marginal improvement for students without learning disabilities. Rather than providing an unfair advantage in the class, extended time for exams allows these students to demonstrate their level of mastery of the course objectives, rather than reflecting the deficits innate to their learning disabilities. In other words, it ‘levels the playing field.
