Public schools, independently run
A charter school is a tuition-free public school run by an independent nonprofit under a performance contract (a “charter”) with a public authorizer. In exchange for freedom from some district rules, it is held to academic, financial and operational targets and is reviewed on a cycle, usually every five years. The federal Charter Schools Program is the main startup funder.
Charters are a large sector: federal data (NCES Digest 2022) counts 7,847 public charter schools among 99,239 public schools. But the law is uneven, the Education Commission of the States reports 46 states plus DC have charter laws; North Dakota's 2025 law is the newest, and Nebraska, South Dakota and Vermont have none. (Counts differ slightly by source because of how Kentucky's struck-down law is treated, check the current state status.)
Finding your authorizer
The National Association of Charter School Authorizers notes that nearly 90% of authorizers are local school districts, and in six states districts are the only option. Other states add independent chartering boards (the DC Public Charter School Board, Colorado Charter School Institute, Indiana Charter School Board, and commissions in Alabama, Tennessee and Georgia), state education agencies or boards, universities (SUNY, Central Michigan), and even city governments and nonprofits. Your first task is identifying which authorizer you can apply to, and that decides your deadlines and rubric.
Charter-friendly vs. not
The National Alliance for Public Charter Schools ranks state laws each year. Its 13th edition put these at the top and bottom:
This matters because the same application is far more likely to be approved, and far better funded, in a state with multiple authorizers and strong startup support.
What a charter petition contains
A charter application (or petition) is a detailed proposal. Expect to cover:
- Educational program and theory of action
- Evidence of community need and enrollment demand
- Governance structure and founding-board bios
- A multi-year budget and cash-flow plan
- A facilities plan
- Staffing, special-education and English-learner plans
- Enrollment, lottery and discipline policies
- Measurable performance goals
Most authorizers add a capacity interview with the founding board and a public hearing. Nearly all states require a founding board of about five to seven members as part of the petition.
Real timelines and deadlines
Plan on roughly 18 to 36 months from forming the team to opening day: 6–12 months to build the team and write the application, 4–9 months for authorizer review, then a 12–18 month pre-opening year (the federal planning grant funds up to 18 months). A few concrete state deadlines:
Appeals and funding
Denial is not always the end. Many states let you appeal a district's no to a state board or commission, Alabama (to the Public Charter School Commission within 30 days), Colorado (to the State Board within 30 days), Tennessee (to the Public Charter School Commission, which can become your authorizer), West Virginia (to the state board within 30 days), and Florida (to the Charter School Appeal Commission). In some states your only route is to reapply.
On money: the main startup source is a federal CSP subgrant, applied for through your state, with ceilings that run roughly $315K to $1.9M per school (California's max is $1.9M over 36 months; Georgia's up to $1.5M; Tennessee's $750K). FY2024 state-entity awards totaled about $377 million nationally. State per-pupil funding begins only once students enroll, and facilities funding is usually thinner than for district schools.

Frequently asked questions
- How much does it cost to start a charter school? Roughly $0.3M to $2M or more before opening. The federal Charter Schools Program provides startup subgrants from about $315,000 to $1.9 million per school depending on the state; state per-pupil funding then begins at enrollment.
- How long does it take to open a charter school? Commonly 18 months to 3 years from forming a founding team to opening, depending on your state's authorization timeline, facilities and funding.
- Who approves a charter school? A public authorizer. Nearly 90% are local school districts; many states also allow independent charter boards, the state education agency, universities, and in a few cases cities or nonprofits.
- Can a private school become a charter school? Only by ceasing to operate as a private entity, obtaining a charter from a qualified authorizer, and reopening as a public school that meets all state requirements.
- What if the district denies my application? Many states allow an appeal to a state board or independent commission, often within 30 days. Rules vary by state, and in some states reapplying is the only option.
