The purpose of this literature review is to summarize existing research on controversial and innovative accommodations (and accessibility tools) to inform policy decisions. This literature review was very well-organized with various sections focusing on a review of studies related to specific accommodations. While it provides valuable information to inform policy decisions, it is somewhat technical in its presentation which might limit the audience that would find it useful. Review of literature reinforces the need for more technical studies to help provide additional data to inform policies relative to use of accommodations and accessibility tools.
