The Charter Schools Program (CSP) is the nation's only source of dedicated federal funding to support the creation, expansion, and replication of public charter schools. At its fiscal year 2022 funding level of $440 million, the CSP amounts to less than 1% of federal spending on K-12 education but has a significant impact on the communities that charter schools serve. This annual report explores the impact of the CSP on communities around the country and makes the case for increased funding for the program. In the report, we explain the charter school model, offer a brief history of the CSP, profile inspiring grantees, and address persistent misconceptions. Charter schools are a vital part of the public school ecosystem, and by advocating for the CSP, we can help more students have access to a public school that meets their unique needs.
