Replication of successful charter schools is a promising strategy to rapidly increase the number of new high-quality charter schools available to children. Replication strategies also hold significant potential for district reform agendas and, specifically, efforts to identify school operators to turn around persistently low-performing schools. This guide, written by Lauren Morando Rhim for the National Association of Charter School Authorizers (NACSA), outlines the critical considerations and makes recommendations to state policymakers who want not only to permit but to explicitly and vigorously promote replication of successful charter schools. Recommendations include clearly defining success worth replicating, removing or avoiding charter caps, allowing charter boards to govern multiple schools, and streamlining application procedures for potential replicators while maintaining rigor.
