Universal design of assessment has been an important step forward in making tests more accessible to students with disabilities. An issue affecting the universal design approach is the need to review individual items, potentially hundreds of them. Ideally, there would be a statistical procedure available that would first identify items that are potential sources of problems for students with disabilities. This paper illustrates one method of determining whether items are functioning differentially for students with disabilities in comparison to their non-disabled counterparts. Using various statistical analysis techniques, a large statewide mathematics data set was investigated for items that may have design issues. Multiple methods were used as a means for compensating for the lack of statistical power that is often present when analyzing data for populations with small group sizes. Results indicated that items can be flagged for further review based on differential functioning across disability groups or types of analysis.
