Paying for Private School in Arizona (2026-27 Guide)

Arizona families pay for private school with three sources: an Empowerment Scholarship Account (ESA) funded by the state, scholarships from School Tuition Organizations (STOs) funded by donors who get a state tax credit, and financial aid from the school itself. School aid can sit alongside either of the first two, but an ESA and an STO scholarship cannot be used for the same student in the same year. Which route fits depends on where your child is in school now, your income and your timing.

The three sources at a glance

Each has its own page: ESA, tax-credit scholarships and school financial aid.

How they combine, and where they conflict

ESA and STO scholarships do not mix in the same year. When a parent signs the ESA contract, they agree to "not accept a scholarship from a school tuition organization pursuant to title 43 concurrently with an Arizona empowerment scholarship account for the qualified student in the same year" (A.R.S. 15-2402(B)(3)). ADE's support page says receiving an STO scholarship while on an ESA "is a contract violation and can result in termination". A student moving from an STO scholarship to an ESA must repay the STO before signing the contract, and the Department of Revenue's STO manual says all STO money paid to the school for that contract year must be returned regardless of when the ESA contract was signed. One STO says different sources may be used in separate quarters; another says an ESA student is not eligible for any award in the same school year. Treat it as one or the other for the school year, and get anything else in writing from the STO and the school.

ESA and school aid. The ESA contract's conditions concern public-school enrollment and STO scholarships; they do not mention a school's own aid. Each school decides how it treats ESA money when it calculates need, so ask before you apply for aid.

STO scholarships and school aid. These are commonly held together. Ask the school whether it expects families to apply to STOs first and how it adjusts its aid when an STO award arrives.

Public school enrollment. An ESA requires withdrawal from the district or charter school when the contract is signed, and STOs may not award scholarships to students who are enrolled in a district or charter school at the same time. Neither source pays for public school.

A worked example

Suppose your family arrives in Arizona in summer with a child entering grade 9, and you choose a private high school charging about $14,500 a year, close to the 2026-27 Arizona private high school average of $14,464 reported by Private School Review (as of October 2026).

On the ESA route, you apply through the ADE portal and, once the contract is signed, the money arrives in four quarterly deposits to a ClassWallet account from which you pay the school. The 2025-26 chart put a grade-9 award without a disability between $7,105 and $10,540, and the most common award that year was $7,247. If your child's award is $7,247, roughly half the tuition is left for you to cover, and you cannot accept an STO scholarship that year. The school's own aid, if it offers any, may reduce the rest.

On the STO route, your child meets a "switcher" condition because the family moved from out of state. If your household income for a family of four is at or below $110,034 (the 2025-26 table), the corporate low-income program can award up to $8,300 for grades 9 to 12, and individual-credit STOs can add awards on top, each as their donations allow. You add the school's aid to that. You do not sign an ESA contract that year. If your income is above the table, the STO route rests on the individual-credit programs alone, and the amounts depend on what donors gave and how each STO allocates.

The honest comparison is not "which pays more" but "which is certain". The ESA amount is set by formula and arrives on a schedule. STO awards are discretionary and can be larger or smaller than an ESA, and the school's aid office usually knows which way they tend to go for its families.

Which route fits your situation

If your child is in an Arizona public school now: both doors are open. A student who attended public school for at least 90 days of the prior year is switcher-eligible for STOs; an ESA requires withdrawing from the public school when you sign. Compare the ESA amount for your child's grade with what the school's aid office says STOs typically award its students.
If your child is already in private school, here or in another state: any K-12 private-school student can receive the basic STO scholarship, and moving from out of state is a switcher condition. An ESA is also available. Pick one for the year.
If you want to homeschool: the ESA is the relevant source, since its funds may be used for home education expenses; STO scholarships pay private-school tuition only. ESA students do not file the county homeschool affidavit; the Maricopa County School Superintendent's office asks families not to file one for a child who has received an ESA. See homeschool.
If your child has a disability: the ESA pays more, by category, from $7,247 up to $47,725 in 2025-26, and the corporate STO program for students with disabilities or a foster-care history is also open. See IEP and 504 plans.
If you are arriving mid-year: ESA applications are accepted year-round and processed within 30 days; a new ClassWallet account takes about three weeks to set up and fund. STO timing varies by organisation; some award several times a year. See mid-year enrollment.
If you are considering boarding school: an ESA covers tuition and fees, not room and board, and the amounts are a fraction of a boarding bill. See boarding schools.

Sources and where to verify

Frequently asked questions

Can I use an ESA and a tax-credit scholarship at the same time?

No. The ESA contract requires you not to accept an STO scholarship for the same student in the same year (A.R.S. 15-2402(B)(3)), and ADE treats it as a contract violation. If you move from an STO scholarship to an ESA, the STO money for that contract year has to be repaid first.

How much does an Arizona ESA pay?

For 2025-26, ADE's chart listed $7,105 to $10,540 for a student in grades 1 to 12 without a disability and $4,718 to $6,205 for kindergarten; disability categories ran from $7,247 up to $47,725. ADE had not published a 2026-27 chart as of 11 October 2026.

Does an ESA cover full private school tuition?

Sometimes, at lower-cost schools. Private School Review's 2026-27 average Arizona private school tuition is $11,237, so a typical ESA award covers most of an average elementary tuition and less of a high school's. The rest comes from STO scholarships (in a non-ESA year), school aid, or your own payment.

Can a school give me financial aid if I have an ESA?

The ESA rules do not forbid it; the school decides. Ask the aid office how it counts ESA funds when it calculates need.

We just moved from another state. Do we qualify for switcher scholarships?

Yes, moving from out of state is one of the switcher conditions in A.R.S. 43-1603, which also opens the corporate low-income program if your income is at or below the table. See tax-credit scholarships.

What if we cannot decide before school starts?

Enroll first and sort out funding in the weeks after. ESA applications are processed within 30 days year-round, and several STOs award more than once a year, so a child who starts in August can still be funded for the year. Just do not sign an ESA contract and accept an STO award for the same year.
