This report presents descriptive findings on school practices in 12 states for schools explicitly held accountable for the performance of the students with disabilities (SWD) subgroup. The study found that, when surveyed in 2011, elementary schools accountable for the SWD subgroup were 15.8 percentage-points more likely than never-accountable elementary schools to report moving students with disabilities from self-contained settings to regular classrooms over the previous five years. Middle schools accountable for the SWD subgroup were 16.7 percentage-points more likely than never-accountable middle schools to report moving students with disabilities from self-contained settings to regular classrooms over the previous five years.
