This state policy guide looks at partnerships between charter schools and community, faith-based, and for-profit organizations as one way for these schools to access essential goods and services. Each type of partnership poses specific challenges and opportunities, and, based on a review of charter school legislation and interviews with state charter school administrators, the guide explores ways in which state laws and policies address partnership development. Community involvement is included as one intention of the charter school law in 13 states. Fifteen states require evidence of community involvement or support in the charter school application, and 5 states encourage community involvement on the charter school board. State laws and policies are more restrictive around partnerships between charter schools and faith-based organizations: 15 states prohibit faith-based organizations from applying to open a charter school, 26 states include broad restrictions against the involvement of faith-based organizations with charter schools, and 3 states allow partnerships with faith-based organizations solely for facility use. For-profit involvement is restricted in some cases and allowed in others: Laws in 16 states prohibit for-profit organizations from applying to open a charter school; in two states, charter schools must report any involvement with for-profit entities. Thirteen states allow partnerships with for-profit organizations for facilities, 17 states allow partnerships for services, and three states allow for-profit organizations to apply to open a charter school. The guide outlines the pros and cons of each policy option with illustrative examples from existing state law and practice. It raises issues that state policymakers may want to consider related to charter school partnerships and aims to help them identify approaches to partnerships that best meet the needs of charter schools in their states.
