This document synthesizes the findings from the evaluations of four statewide programs designed to provide support for underperforming schools and districts in California as part of the state accountability system: (1) Immediate Intervention/Underperforming Schools Program (II/USP); (2) High Priority Schools Grant (HPSG) Program; (3) School Assistance and Intervention Teams (SAIT); and (4) District Assistance and Invention Teams (DAIT). This overview outlines the cross-cutting findings and recommendations from the evaluation studies of these programs. In addition, this document includes two charts. The first provides programmatic details for each effort, including timeline, school or district selection criteria, state funding for implementation, and additional technical support provided. The second chart summarizes the evaluations of each program, including study design and findings related to student performance outcomes as well as implementation.
