Public schools are funded by the government, free to attend, and open to every child in a district. Private schools charge tuition and set their own admission criteria. Charter schools are publicly funded but operate independently with more flexibility than traditional public schools. Each type has different rules around enrollment, oversight, and curriculum.
The One Thing That Shapes Everything Else: Funding
How a school gets its money determines almost everything else about how it runs — who can attend, who sets the rules, and what the school is required to offer your child.
Public schools are paid for through a combination of local property taxes, state funds, and federal dollars. Because taxpayers fund them, they are accountable to elected school boards and must follow state education law. That accountability is the reason they cannot turn a child away based on where they live within the district.
Private schools operate on tuition, donations, and sometimes endowments. Because they do not take public money (with some state-specific exceptions around voucher programs), they answer to their own governing boards rather than to a public authority. That independence lets them set their own admission standards and design their own curriculum.
Charter schools sit in between. They receive public funding — typically per-pupil dollars from the state — but they operate under a contract, called a charter, granted by an authorizer. That authorizer might be a school district, a university, or a state agency, depending on where you live. The charter gives the school flexibility to operate differently from a traditional public school in exchange for agreeing to meet specific performance goals.
Who Can Enroll
Traditional Public Schools
Your neighborhood public school must accept your child. Assignment is almost always based on your home address, though some districts allow transfers within the system. There is no application, no interview, and no tuition.
Charter Schools
Charter schools are public schools, so they cannot charge tuition and cannot use academic performance or family background to screen applicants. When more families apply than there are seats, most charter schools are required by law to hold a lottery. Sibling preferences and geographic preferences are common, but the rules vary by state and by individual school.
One practical note: charter schools often have their own enrollment windows and lottery deadlines that do not match the traditional public school calendar. If you are considering a charter school, find out its specific timeline early.
Private Schools
Private schools set their own admissions criteria. Some are highly selective and require applications, testing, and interviews. Others are less competitive and admit most families who apply and can pay. Admission decisions rest entirely with the school, and there is no public appeals process the way there might be in a district enrollment dispute.
Financial aid is available at many private schools, but the amount, eligibility criteria, and process differ from school to school. That ground is covered separately in this pillar.
Who Is in Charge
For traditional public schools, governance runs through an elected school board that answers to voters. The superintendent reports to that board. State education agencies set graduation requirements, curriculum standards, and testing rules that every public school in the state must follow.
For charter schools, the day-to-day governing authority is usually a nonprofit board that runs the school. Above that board is the authorizer, which reviews the school's performance and can renew, put on probation, or close the school if it fails to meet the terms of its charter. Charter schools must follow most of the same state laws that apply to traditional public schools — including special education requirements — but they often have more latitude on things like schedule, staffing, and instructional approach.
For private schools, a board of trustees or directors governs the institution. Accreditation bodies provide a layer of external review, but there is no government body that oversees the curriculum or holds the school accountable for student outcomes the way a state agency does for public schools.
Teachers and Staff
In most traditional public schools, teachers are required to hold a state teaching license. Many are represented by a union, and their pay and working conditions are governed by a collective bargaining agreement.
Charter schools vary. Some states require charter school teachers to hold the same licenses as their public school counterparts. Others give charter schools more flexibility to hire differently credentialed staff. Whether charter school teachers are unionized depends on the individual school and state law.
Private schools set their own requirements. Some prioritize subject-matter expertise over formal licensure, especially at the secondary level. Others require or prefer state licensure. There is no uniform rule.
What Schools Are Required to Offer
This is where the differences become most practical for families who have a child with specific learning needs.
Every traditional public school and every charter school must follow the Individuals with Disabilities Education Act. That means if your child is eligible for special education services, the school is legally required to evaluate, plan, and provide those services at no cost to you. The same federal obligation applies to both types of public school.
Private schools operate differently. A private school that does not accept federal funding is not bound by IDEA in the same way. Your child may still have rights under Section 504 and the Americans with Disabilities Act if the school receives any federal assistance, but the full range of services available in a public school may not be available in every private setting. If your child has an IEP or receives special education services, this is one of the most important questions to ask before you consider a private school. The article on special education placement options in this pillar covers that in more detail.
Accountability and Transparency
Because public schools and charter schools receive government funds, they are subject to public records laws. You can typically request budget information, board meeting minutes, and aggregate student performance data. State report cards for public and charter schools are published online in every state.
Private schools are not subject to the same transparency requirements. They may choose to share outcome data with prospective families, but they are not required to.
The Question of Fit
None of these structures is inherently better than the others. The right school for your child depends on what your child needs, what is available in your area, and what trade-offs your family can work with.
A few questions worth asking about any school you are seriously considering:
- How does the school handle a child who is struggling academically?
- What is the process if a conflict arises between a family and the school?
- What does the school's accountability look like — who do they answer to, and how do you reach that authority if you need to?
- What are the actual enrollment steps and deadlines?
Those questions will surface more useful information than any label will.
Key takeaways
- Public schools are government-funded and open to every child in the district; charter schools are also publicly funded but governed independently; private schools run on tuition and set their own rules.
- Charter schools cannot charge tuition or use selective academic admission, but they often have separate enrollment windows and lottery systems.
- Both traditional public schools and charter schools must follow federal special education law; private schools have more limited obligations in this area.
- Private schools answer to their own boards rather than to public authorities, which affects both flexibility and accountability.
- The right type of school depends on your child’s specific needs, what is available locally, and the enrollment requirements you are willing to navigate.
Common questions
Is a charter school a public school?
Yes. Charter schools are publicly funded and tuition-free. They cannot exclude students based on academic performance or family background. What makes them different from traditional public schools is that they operate under a contract with an authorizing body, which gives them more flexibility in how they run.
Can a public school turn my child away?
A traditional public school in your district generally cannot refuse to enroll your child. There are circumstances where districts make transfer decisions, but your child has a right to a public education. If you run into a barrier, the district’s enrollment office and your state education agency are the places to start.
Do charter schools have to provide special education services?
Yes. Charter schools receive public funds and must comply with federal special education law, including the obligation to evaluate eligible students and provide services at no cost to the family. The specific services available can vary, so it is worth asking any charter school directly how they deliver those services.
How is a charter school different from a magnet school?
Both are public and tuition-free, but a magnet school is operated directly by the school district, while a charter school is operated by an independent organization under a charter agreement. Magnet schools are covered separately in this pillar.
What happens if a charter school closes?
Charter schools can be closed by their authorizer if they fail to meet performance goals. When that happens, students are typically reassigned to other public schools. The process and timing vary by state, so it is worth understanding your local district’s policies if you are considering a charter school.
Does a private school have to honor my child’s IEP?
A private school that does not receive federal funds is not automatically bound by IDEA, so it is not required to implement an IEP the way a public school is. Your child may have some protections under other laws. Ask the school directly and speak with your public school district, which retains some obligations even when a child attends private school.
