The 2004-2005 school year was the third year that states were required to report on the performance of students with disabilities on standards-based assessments, and the last year before states were required to test in all grades 3 through 8, and once between grades 10 and 12. This report marks the ninth in a line of National Center on Educational Outcomes reports that document state public reporting practices, and pays particular attention to present and upcoming federal requirements in public reporting. Additional analyses were conducted as well, including an examination of accommodations reporting, a look at disaggregated student group reporting, and a Web site analysis to determine the accessibility of states' public reporting of participation and performance data. Overall, all 50 states and 5 unique states reported some disaggregated assessment results for students with disabilities for the 2004-2005 school year. This report reinforces what was found in 2003-2004. States continue to improve their public reporting practices, especially for alternate assessments, but it is gradual, and there are still improvements to be made. This report discusses the results of the study and provides recommendations for how states can continue to improve their public reporting practices.
