NERA Conference Proceedings 2010
In a statewide achievement test, the use of a calculator is often allowed as an accommodation for students with disabilities (SWD). The purpose of the accommodation is to eliminate the disadvantage faced by SWDs relative to peers without disabilities with the same level of overall mathematics proficiency. However, it is important to determine if the accommodation has changed the construct and meaning of the test scores. One way of examining whether the construct has changed due to the accommodation is to compare performance on the assessment for SWDs to peers without disabilities, controlling for differences in proficiency. In this study, …
