A report describing the first comprehensive analysis conducted by the National Center on Educational Outcomes (NCEO) of trends in the public reporting of state assessment results for students with disabilities. The study followed NCEO's four analyses of public reporting since the federal No Child Left Behind Act of 2001. More states are reporting assessment data for students with disabilities disaggregated by grade level and content area. States have also improved their data collection systems that make this type of reporting possible but the number of states for which data were available across the four years was relatively small. Based on the states with data across years, average percentages of students with disabilities performing at the proficient or above level showed moderate increases across the four years for both reading and math in elementary and middle schools but not in high schools. Trend data also showed higher percentages of elementary school students demonstrating proficient or above performance in reading and math than their counterparts in middle and high school. Trends in the Participation and Performance of Students with Disabilities is a brief summary of this report.
