For this online database, all studies summarized in Tindal and Fuchs are included, with the exception of those that considered collaborative groups, performance-based assessment, computer adaptive testing, and instruction in test-taking strategies as accommodations. Additional studies were identified for inclusion in the accommodations bibliography using a method similar to that used by Tindal and Fuchs. Four indexes (Digital Dissertations, ERIC, Education Abstracts, and PsycInfo) were searched for studies using the following keywords:

Accommodation papers presented at annual meetings of the following organizations were also identified: American Educational Research Association, Council of Chief State School Officers, and National Council on Measurement in Education.
To be summarized and included in this online bibliography, studies need to involve either (1) experimental manipulation of an accommodation, (2) investigation of the comparability of test scores across accommodated and non-accommodated conditions, or (3) examination of survey results on teachers knowledge and/or perceptions of accommodations. Emphasis is placed on including studies that examine testing accommodations as opposed to instructional accommodations. Although not a requirement for inclusion, studies involving accommodations for students with disabilities are the primary focus of the bibliography.
