“…We documented substantial differences in the participation of youth with severe disabilities and youth with EBD across almost half of the 20 activities, suggesting that disabilityrelated support needs may represent one salient factor limiting the participation of certain youth. Participation in general education, vocational education, extracurricular and other transition-related activities historically has been especially limited for adolescents with severe disabilities, perhaps more so than any other disability category (Kleinert, Miracle, & Sheppard-Jones, 2007;Williamson, McLeskey, Hoppey, & Rentz, 2006). Indeed, special educators who serve these youth often identify an array of issues that influence their decisions to limit or promote involvement in school and community activities, such as the nature of students' instructional needs, challenging behaviors, and availability of needed supports (Brozovic, Stafford, Alberto, & Taber, 2000;Trainor, Carter, Owens, & Swedeen, 2008).…”
