This review of evidence gathered from formal evaluations of reconciliation programs is part of a larger effort undertaken by CDA in partnership with the Peacebuilding Evaluation Consortium (PEC). As part of this consortium effort, the Alliance for Peacebuilding (AfP) has published a review of theories of changes and indicators in use by violence reduction programs, and CDA has developed this synthesis of available evidence and reported outcomes from evaluations of reconciliation programming. Overall, PEC sub-sector reviews are not intended to draw definitive conclusions on program effectiveness, but instead to launch a process of substantive learning that can be continued by PEC members and other peacebuilding organizations and researchers. Our syntheses of existing evidence identify gaps in current knowledge that may require additional research efforts, beyond project- and program-level evaluations.
