This study examined the impact of CIRCLES on students¡¯ self-determination and participation in individualized education program (IEP) meetings. Forty-four schools located in the Southeast United States were assigned randomly into either the CIRCLES or business-as-usual (BAU) conditions, and 877 high school students with disabilities were included in the analyses. Two-level hierarchical linear models, with students at Level 1 and schools at Level 2, examined the effectiveness of CIRCLES. Results indicated students in the CIRCLES condition had higher levels of self-determination (Hedges¡¯s g = .06¨C.38) and greater IEP participation (Hedges¡¯s g = .77).
