Lovett, B. J. (2010). Extended time testing accommodations for students with disabilities: Answers to five fundamental questions . Review of Educational Research , 80 (4), 611–638. https://doi.org/10.3102/0034654310364063

The extended time accommodation is examined in this study, and the author addresses the issue of validity of the impact of this accommodation.

This literature review identified 20 studies of relevance to the extended or extra time accommodation to address two questions, and also considered a broader set of research to address the other three questions. The relevant studies appear to have been completed within the U.S. educational system.

There were various dependent variables in the studies of this literature review.

This literature review sought answers to various issues including how extended time influences construct validity, and the possibility of benefits of extended time for students without disabilities. Other issues include the potential for students with disabilities to complete non-accommodated tests, eligibility considerations related to specific disabilities, and the accommodation decision-making process as a whole.
