The purpose of the current analysis is to update information on these policies that was last reported by NCEO in 2006 (based on 2005 data). In this analysis, policies from all 50 states, plus 8 of the unique states, were reviewed. The current analysis of states' 2007 participation and accommodation policies found that state policies on participation and accommodation continue to evolve, and that they have become more detailed and specific than in previous years.enK-12 educationdisabilityeducational accountabilityeducational assessmenteducational accommodationsReport
