This research and development report provided two measures of change in each NAEP participating state's inclusion rate taking into consideration the prevalence of different types and severities of disabilities and the accommodations the states permits in their own testing programs compared to those allowed by NAEP to students with disabilities in 4th- and 8th- grade reading and mathematics assessments. The study reported results for all 50 states and District of Columbia and used data from the 2005, 2007, and 2009 NAEP assessments of fourth- and eighth-grade reading and mathematics. This two approach methodology—nation-based and jurisdiction-specific— analyzed the inclusion rates from different perspectives. The analysis indicates the status and change in state level inclusion rates. The report presented status of inclusion in 2009 and changes in the rates from 2007 and 2005.
