Meta-analysis on the Effectiveness of Extra time as a Test Accommodation for Transitioning Adolescents With Learning Disabilities

The accommodation of students with learning disabilities (LD) on mandatory high stakes tests continues to heighten concern over the equity and effectiveness of current practices. As students transition from high school, they are required to complete timed graduation tests and postsecondary entrance examinations. The most common accommodation accessed by transitioning adolescents with LD is extended time. In order to inform test accommodation practices, a meta-analysis was conducted to address whether test scores from accommodated (i.e., extended time only) and standard test administrations are comparable for transitioning adolescents with LD as compared to their normally achieving peers. The results of the meta-analyses raised more questions than answers and highlighted the need for future research in this area.
