Modifying standardized tests for students with disabilities is a complex issue. Tests should be modified only when alternative measures do not exist. Testing professionals should always be cognizant of the fact that whenever modifications are made, normative interpretations must be made very cautiously. In addition, the accommodations that were made should be described and the examiner should continually ask whether the accommodations significantly alter the format of the test or change the nature of the test. In this document, many issues related to test modification are highlighted and a step-by-step procedure for developing appropriate testing accommodations is presented. (Contains 10 references.)
