This article discusses accommodation-related research findings of a 3-year federally funded research study. The researchers sought data on light/acoustics, adaptive furniture, proctor or scribe, seat location/proximity, all response accommodations, all setting accommodations; data were also summarized for use of any and all accommodations.

The data analysis regarding accommodations and participation represents 18 states in the U.S. at the elementary level in reading and math, 17 states in middle school reading and math, 16 states in high school reading, and 15 states in high school math. All states had data for accommodations, but only a maximum of 18 states had usable data regarding participation rates for elementary students.

The data analysis includes an examination of accommodation policies and discipline rates in all 50 states, participation rates math and reading state assessments in states for which data were available, and the relationships among these data as indicated by statistical correlations. (Performance scores in relation to accommodations use were not examined in this study.)

The proctor/scribe accommodation correlated more strongly with higher participation rates than any other specific accommodation.
