What Is a Charter School?
A charter school is a public school that operates as a school of choice under a charter with a public chartering agency. Charter schools are tuition-free and cannot be affiliated with a religious institution. They are exempt from significant state and local regulations but still follow public school regulations, per the US Department of Education NCSRC.
Albert Shanker introduced the concept in 1988. Minnesota passed the first charter law in 1991, and the first school opened in St. Paul in 1992. National Alliance data shows 46 states passed charter legislation, with 45 states plus DC, Guam, and Puerto Rico hosting active programs. About 62 percent operate as single-site schools. Enrollment rose 12 percent over five years.
How Do Charter Schools Work?
Charter schools operate under a written contract with a public chartering agency, such as a school district, university, or state board. This charter defines the school’s mission, academic goals, and accountability requirements. The authorizing agency monitors results and can revoke the contract if performance targets are not met.
- Tuition-free education for all enrolled students
- Public oversight through an authorizing agency
- Independent governance over budget, staffing, and curriculum
Public charter schools manage their own budgets, hire their own staff, and design curricula independently. This flexibility lets school governance adapt quickly to community needs. The federal National Center for Education Statistics tracks enrollment and performance data for these publicly funded institutions across the country.
When demand exceeds available seats, an admissions lottery determines which students can enroll. This random selection process keeps access open and fair for all families. By law, these schools cannot charge tuition, affiliate with religious institutions, or require entrance exams for admission.
Where Did Charter Schools Come From?
The concept emerged in 1988 when labor leader Albert Shanker proposed a new kind of public school that would operate with greater autonomy. He envisioned these institutions as a school of choice, free from many traditional district rules while still serving public students and remaining accountable to a public authorizing agency.
Minnesota passed the nation’s first charter law in 1991. The following year, the first charter school opened in St. Paul, giving families a publicly funded alternative to their assigned district campus. Congress then created the federal Charter School Program in 1994.

Since then, the movement has expanded steadily across the country. According to NCES, 46 states have passed charter legislation, and enrollment increased 12 percent over five years. About 62 percent of these schools remain single-site operations.
Today, 45 states plus DC, Guam, and Puerto Rico host operating charter campuses serving local communities. The model continues to attract families seeking alternatives within the public system, offering flexible programs and varied instructional approaches to learning.
Charter School vs Public School
When weighing charter school vs public school options, families look at funding, governance, admissions, and oversight. Both serve students as tuition-free public schools, but they differ in structure, flexibility, and how they are held accountable.
| Category | Charter | Traditional Public |
|---|---|---|
| Funding | About 75 cents per dollar a district receives | Full district funding |
| Admissions | School of choice; admissions lottery if oversubscribed | Assigned by attendance zone |
| Governance | Independent board under a charter | Elected or appointed school board |
| Rules | Exempt from many state and local rules | Full state and local regulations |
| Religious affiliation | Cannot be religiously affiliated | Cannot be religiously affiliated |
Charter schools operate under contracts with a public authorizing agency, which sets performance goals and reviews results. If demand exceeds available seats, a random lottery decides who enrolls. Both models remain tuition-free and serve the public.
The main difference lies in school governance and regulatory flexibility. These public charters gain freedom from many regulations in exchange for accountability to their authorizer. Traditional public schools follow standard district policies without a charter contract.
What Do Outcomes and Criticisms Show?
A 2023 CREDO study reported average gains of 16 additional days of learning in reading and 6 additional days in math for charter students. These results represent averages and vary across states and student groups.
Critics point to funding gaps, mixed results across campuses, and concerns about transparency. Supporters highlight school choice, innovation, and local accountability. When weighing charter school vs public school options, families should compare specific campuses rather than rely on national averages alone.
- Pros
- Tuition-free public schools of choice
- Greater flexibility in curriculum and governance
- Accountable to an authorizing agency
- Concerns
- Receive about 75 cents per dollar of district funding
- Results vary widely across campuses
- May close if charter terms are not met
What is the point of going to a charter school?
Charter schools offer families a tuition-free school of choice with flexible programming that may fit student needs.
What is the downside of charter schools?
Funding is lower than district schools, results vary by campus, and oversubscribed schools use a lottery.
Is a charter school the same as public?
Yes. Public charter schools are public schools that follow public regulations but operate under a charter contract.
