Trends in the Participation and Performance of Students with Disabilities (NCEO Brief)

Jason R Altman, Martha L Thurlow, Rachel F Quenemoen


A brief describing the results of an analysis of trends in the public reporting of state assessment results for students with disabilities. The analysis was conducted on a compilation of publicly reported assessment data gathered from state Web sites and personnel during the data collection for four previous analyses completed by the Institute's National Center on Educational Outcomes (NCEO). These data were supplemented with data obtained from current state education Web sites. This trend analysis covered the years 2001-02 to 2004-05, and examined both participation and performance. The goal of the analysis was to determine:

  1. Whether progress has been made by states in publicly reporting the participation and performance of students with disabilities on state assessments
  2. The nature of trends in the four years of participation and performance data for students with disabilities.

This brief is based on the 2008 report, Technical Report 50: Trends in the Participation and Performance of Students with Disabilities, published by NCEO.
