Valid, reliable measurement requires special consideration during test development & administration.


The principles of Universal Design support the development of assessments that are accessible to all students. Research in the use of accommodations during test administration is intended to support the validity of inferences based on test results. Federal policy requiring states to assess all students and to report the disaggregated results of students with disabilities motivated an increase in research conducted in this area, which in turn has improved skills measurement for students with disabilities.
