This year 2001 report examines the effect of a read aloud accommodation on the state reading and math assessments used by the Missouri assessment program. The study used extant test administration data for multiple-choice math and reading test items administered to 3rd and 4th grade students. Four student groups were created to help control for confounding effects. A differential item function (DIF) analysis was run on the data using BILOG-MG, which compared item difficulty estimates across several groups simultaneously. The findings lead to a discussion of how to determine who should benefit from an accommodation, and whether a reading test measures the reading construct differently for students with a reading disability than for students without disabilities. The report recommends further research and suggests that replicating the study is needed to confirm the results.
