NCEO - Technical Report 41 - Analyzing Results of Large-scale Assessments to Ensure Universal Design

2011

A report illustrating 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.
