Charter school guide
Charter schools vs public schools
The question contains a mistake worth clearing up first: charter schools are public schools. The real comparison is between a charter school and a traditional district school — and there the differences are concrete.

Side by side
| Charter school | District school | |
|---|---|---|
| Who can attend | Anyone who applies, statewide or district-wide; lottery if oversubscribed | Students assigned by home address |
| Tuition | Free | Free |
| Governance | Non-profit board under a fixed-term charter with an authorizer | Elected school board and district administration |
| If results are poor | The authorizer can decline renewal and close the school | The district is required to improve it; closure is rare |
| Rules | Exempt from parts of the state education code and district bargaining agreements | Full state code and district agreements apply |
| Funding | Per-pupil public funding; facilities usually paid from the same pot | Per-pupil funding plus district facilities and capital budgets |
| Transport | Sometimes; many charters run no buses | Usually provided within the attendance zone |
| Typical size | Median 362 students in this directory | Commonly larger, especially at high-school level |
Admission is the difference families feel first
A district school takes your child because of where you live. A charter school takes your child because you applied and, if the school was oversubscribed, because a lottery drew your number. That single difference drives most of the others: application windows, waitlists, and the fact that a charter place is never guaranteed by moving house. The process is set out in the lottery and waitlist guide.
Accountability runs in opposite directions
A district school answers to an elected board, and a failing one is usually restructured rather than closed. A charter school answers to its authorizer under a contract with an expiry date. Renewal is a genuine decision, and charters do get closed for weak results, weak finances or weak governance.
For a family, this cuts both ways. The threat of closure is a real quality mechanism, and it is also a real risk: a school that loses its charter mid-way through your child’s education means an unplanned move. Asking when the current charter term ends is a fair question to put to any school you are considering.
Size, staffing and the things people assume
Charter schools are typically smaller: half of the 8,068 schools in this directory enrol fewer than 362 students. The median charter reports 16.9 students per teacher — but that is a staffing ratio, not a class size, and it counts every teacher on the payroll including specialists. Do not use it as a proxy for how many children sit in the room.
Two assumptions worth dropping. Charter schools do not select on academic ability — that is a magnet school, which is a district school with an entrance requirement. And charter schools are not private schools: no tuition, no religious instruction, no discretionary admissions. If you are weighing “free” options, both charter and district schools are free.
How to actually decide
- 1. Name two or three specific schools, including your assigned district school. Categories cannot be compared; schools can.
- 2. Check the grade span. A K–8 charter means another admissions round before ninth grade.
- 3. Work out the commute for the real school run, in traffic, with no bus.
- 4. Ask each school the same three questions: teacher turnover, how special-education services are delivered, and when the charter comes up for renewal.
- 5. Apply to more than one. A waitlist is not a place.
Frequently asked questions
What is the main difference between a charter school and a public school?
A charter school is a public school. The difference is not public versus private, it is who runs it and under what rules: a charter school operates under a fixed-term contract with an authorizer instead of under a district’s standard governance, and it admits students by application rather than by home address.
Which is better, a charter school or a district school?
Neither, as a category. Research finds wide variation inside both types, with results depending far more on the individual school than on its label. Compare two named schools, not two categories.
Do charter schools take money from district schools?
Funding generally follows the student, so a district loses per-pupil revenue when a student transfers, while keeping some fixed costs. Whether that constitutes harm is a genuine policy dispute, not a settled fact, and the answer varies with each state’s funding formula.
Do charter schools have to accept students with disabilities?
Yes. Charter schools are public schools and must serve students with disabilities and English learners. What varies is how services are delivered — in-house or purchased from the district — so ask each school directly.
Are charter school teachers certified?
Certification rules vary by state. Some states require the same certification as district schools; others allow flexibility for a share of staff. Ask the school what proportion of its teachers hold state certification and what its annual turnover is.
