Harlem Children's Zone (HCZ) Promise Academy Charter Schools. What Works Clearinghouse Intervention Report

This intervention report presents findings from a systematic review of the "Harlem Children's Zone (HCZ) Promise Academy Charter Schools" conducted using the What Works Clearinghouse (WWC) Procedures and Standards Handbook (version 3.0) and the Charter Schools review protocol (version 3.0). No studies of the "HCZ Promise Academy Charter Schools" that fall within the scope of the Charter Schools review protocol meet WWC group design standards. Because no studies meet WWC group design standards at this time, the WWC is unable to draw any conclusions based on research about the effectiveness or ineffectiveness of the "HCZ Promise Academy Charter Schools" on elementary, middle, and high school students. Research that meets WWC design standards is needed to determine the effectiveness or ineffectiveness of this intervention.
