ESA or Catholic Education Arizona? How Diocese of Phoenix families make the one-or-the-other choice

Every spring, parish school offices across the Valley field the same question from parents at the registration table: should we take the ESA this year, or stay with our Catholic Education Arizona scholarship? The Diocese of Phoenix gives a clear rule on the first part of that question and leaves the second part to each family. Here is what the diocese, its STO and the state actually say, and how to think through the choice for a child at a parish K-8 or a Catholic high school.

The rule the diocese repeats

The Catholic Schools Office's frequently asked questions page tells families they must choose either an STO scholarship or the ESA for a given child in a single academic year. That is not a diocesan policy layered on top of state law; it comes straight from the ESA contract. Under A.R.S. 15-2402, an ESA parent agrees not to accept a scholarship from a School Tuition Organization concurrently with the account in the same year the agreement is signed. ADE lists taking an STO scholarship while receiving ESA funds as prohibited and names it in the handbook as a likely cause of termination.

Two details soften the edges. First, the rule is per child: a family with a seventh-grader at a parish school and a sophomore at Bourgade or Seton can put one child on the ESA and keep the other on STO awards. Second, leaving the ESA is itself one of the conditions that qualifies a student for switcher and low-income corporate STO scholarships, so a family that tries the ESA and changes its mind is not shut out of the STO pool later.

Why many parish K-8 families take the ESA

The diocese has said plainly that most of its elementary school tuition rates are below the yearly ESA allocation. It cited the roughly $7,000 figure from 2023-24, which is now out of date; ADE's latest chart, an estimate for 2025-26, puts grades 1-12 at $7,105 to $10,540 for a student without a disability, and kindergarten at $4,718 to $6,205. ADE had not posted a 2026-27 chart when we checked.

When the account covers tuition, the money left over stays in the account and can be spent on approved items such as required textbooks, uniforms bought through the school, tutoring and testing. Parish schools also typically discount tuition for registered, active parishioners, and tuition is set by each pastor or school, so the gap or surplus depends heavily on which parish you belong to. Ask the school office for both the parishioner and non-parishioner rate before you compare.

Why some high-school families stay with STO awards

The calculation changes at the high-school level. When a Catholic high school's tuition sits above the top of the ESA range, a family weighing the account against an established STO award is comparing a capped state amount with whatever their STO scholarships, school aid and parishioner rates add up to. There is no general answer. A family whose relatives give heavily to an STO, or whose child already holds multi-year STO awards, may come out ahead on the STO path; a family starting fresh may find the ESA larger and more predictable.

The money involved on the STO side is significant. In fiscal 2025, Arizona STOs received $233.3 million and paid $203.9 million in scholarships statewide, according to the Department of Revenue. Brophy College Preparatory received $2.5 million in original-credit STO money that year, second only to Gilbert Christian Schools among all Arizona schools.

How Catholic Education Arizona fits in

Catholic Education Arizona, the diocese's STO since 1998, describes itself as having raised more than $408 million and awarded more than 165,000 scholarships, with 38 partner schools. The diocese says more than 13,000 donors give it over $20 million a year. It runs a General Scholarship Fund and also lets donors direct gifts to a particular school, which is why parish schools ask families each spring to recruit grandparents, aunts and uncles as donors.

Applications go through FACTS with a $31 per-family fee. For 2026-27, round one ran from February 1 to April 15, 2026 and round two from April 15 to August 21; applications after that are funded as money allows. A similar calendar for 2027-28 is likely but had not been announced. CEA is not the only option: many diocesan schools also appear on IBE, APSTO, School Choice Arizona and APESF lists, and families can apply to several STOs for the same child.

For donors, the tax-year 2026 limits are $787 single or $1,570 married filing jointly under the original credit, and $784 or $1,561 under the switcher credit, which a donor can use only after giving the full original amount. Gifts made through April 15, 2027 can be claimed on the 2026 return.

A short checklist for the registration table

Get the real tuition. Parishioner rate, non-parishioner rate, registration and book fees.
Ask about billing. Is the school a ClassWallet vendor, and will it bill each quarter to line up with ESA deposits in July, October, January and April?
Check your STO history. What did your child receive last year, from which STOs, and are any awards held as multi-year scholarships?
Decide per child. Write down which path each child is on for the coming year so nobody accepts an STO award by mistake while an ESA contract is active.
Mind the dates. An ESA application completed after March 31 starts on or after July 1. CEA's first round has closed in mid-April.
