Although poor interventions produce poor results, most school psychologists lack objective tools to assess intervention fidelity. This workshop will help participants evaluate the degree to which interventions are implemented at the student/classroom level, and systemic capacity to train, support, and deliver academic and behavioral interventions with high fidelity. The procedures in this workshop come from a meta-analysis of treatment fidelity research and from two large-scale evaluations of intervention processes: Chicago's school-based problem-solving model and North Carolina's problem-solving pilot program. Participants will have hands-on practice applying research-based intervention fidelity tools to actual cases and live observations.
