The Charter Schools Office supports The School District of Philadelphia’s Board of Education in its role as an authorizer of brick and mortar charter schools operating in Philadelphia.

An authorizer is responsible for reviewing, evaluating and approving new charters, establishing performance goals for existing charter schools, regularly reviewing and evaluating charter school performance, conducting comprehensive renewal reviews, and sharing information about charter schools and their performance with the public.

Three principles guide our work:

  • Accountability   Improving the School District’s capacity to establish and maintain high standards for its charter schools by measuring charter performance against clear standards and implementing consequences when standards are not met.
  • Autonomy   Preserving charter school independence by focusing on accountability for student outcomes rather than methods, as it relates to curriculum, hiring, and other areas.
  • Equity   Protecting the right of students and families to equal access and fair treatment in Philadelphia’s charter schools.

The School of District of Philadelphia received an evaluation for its work as a charter authorizer by the National Association of Charter School Authorizers (NACSA). The CSO continues to be focused on driving the quality of our own work to support all charter sector stakeholders. The NACSA evaluation is available here.
