Accessible Reading Assessments for Students with Disabilities

Assessments developed and field tested for the mainstream student population may not be accessible for students with disabilities (SWDs) as a result of the impact of extraneous variables, including cognitive features, such as depth of knowledge required, grammatical and lexical complexity, lexical density, and textual/visual features. This study investigates the impact of these features on the performance outcomes of SWDs in the United States. Live test items from two different states with large numbers of SWDs were evaluated for their level of depth of knowledge features, linguistic complexity, two types of lexical features, and textual and visual characteristics. Results suggest that textual features have the greatest impact on the performance of students with different types of disabilities.

Accessibility of Segmented Reading Comprehension Passages for Students with Disabilities

This study explores factors that affect the accessibility of reading comprehension assessments for students with disabilities in grade 8 public school classrooms. The study consisted of assessing students using reading comprehension passages that were broken down into shorter “segments” or “chunks” in order to assess the validity and effectiveness of segmenting and the reliability of assessment in segmenting. The results of the segmenting study indicated that: (1) segmenting did not affect reading performance of students without disabilities; suggesting that it does not compromise the validity of reading assessment; (2) segmenting did not affect reading performance of students with disabilities; and (3) the segmented version had a higher reliability for students with disabilities without affecting the reliability for students without disabilities.
