Description

This year 2005 report illustrates one method for determining whether items on an assessment are functioning differentially for students with disabilities in comparison to their peers without disabilities. The report describes various statistical techniques used with a large statewide dataset for a mathematics assessment, and describes ways to compensate for lack of statistical power when looking at small group sizes. The report concludes that items can be flagged for review using differential functioning or other types of analysis.
