The accommodation studied in this analysis was a change in test organization or layout. Specifically, this analysis examined the provision of extra blank space. There was 50% more blank space than the usual amount on a mathematics test.

One grade 5 student participated in this single-case design study. The participant had a specific learning disability with a severe impairment in mathematics (dyscalculia), moderate impairment in reading and writing; the participant also had attention-deficit hyperactivity disorder (ADHD). The participant attended a small private school in Florida (U.S.).

Baseline performance data were gathered from regular classroom grade 5 math tests. Intervention data came from similar math classroom tests that contained a 50% increase in blank space. Details were reported for each of the classroom tests. These tests included a mixture of multiplication and division items, word problems, and other types of problems.

The comparison of performance data from the two phases—baseline and intervention—found preliminary evidence that the increased blank space had no significant effect on the student's academic performance.
