Summary
Accommodation
This study reviewed the effects of modifications—the most common being simplified language, removal of response option, graphic support, and reorganization of layout (adding white space between questions, bolding key words, breaking one paragraph into several).
Participants
Three groups of grade 8 students participated, including (a) students without disabilities, (b) students with disabilities who would be eligible for a modified assessment, and (c) students with disabilities who would not be eligible for a modified assessment. Participants attended middle schools in four U.S. states: Arizona, Hawaii, Idaho, and Indiana. Demographic data including gender and ethnicity were reported.
Dependent Variable
The dependent variable was scores on computer administered reading and math tests. Questions were drawn from a pool provided by Discovery Education Assessment, and were modified in some conditions.
Findings
Results showed that there were no meaningful differences in reliability between original and modified test items. Evidence suggested that modifications provided a differential boost for students with disabilities who were eligible for the modified assessment. Limitations of the study were reported, and future research directions were suggested.
