Accommodations used by students during test administration were coded by reviewers who viewed videotapes of testing sessions. Accommodations used included: substitutions (objects for pictures), picture or object enhancement (adding color), layout or setup (defined space), instructions or directions (alternate wording), and response (eye-gaze response)—where students communicated test responses via an augmentative or alternative communication system.

Participants were 286 students (143 each from grades 3 and 8) who took the statewide test in Pennsylvania (U.S.). Data from 257 of these students were used to analyze accommodations.

The dependent variable was scores on the spring 2005 administration of the Level A Pennsylvania Alternate System of Assessment (PASA) in reading and math.

Non-parametric data analysis techniques (Kruskal-Wallis and Mann Whitney U) were used. Students with more functional vision performed better overall than students using vision for some or no tasks. Students using more vision to complete tasks also received fewer accommodations, though students with less vision sometimes did not receive accommodations as well, which may present a problem of accessibility and availability of accommodations. The authors note that questions about accommodation use in the classroom still need to be addressed. Limitations of the study were reported, and future research directions were suggested.
