Why Queen Creek, San Tan Valley and Maricopa lead Arizona's ESA growth, and what it means for families there

If you want to see where Arizona's Empowerment Scholarship Account is changing how families school their children, skip central Phoenix and drive southeast on the Loop 202 until the farm fields give way to rooftops. Queen Creek, San Tan Valley and, a little farther south across the county line, the city of Maricopa are where the program has grown faster than anywhere else in the state. This post looks at what the numbers show, why the growth is concentrated there, and what it means for a family in one of those subdivisions deciding what to do for next school year.

What the data shows

When ADE's enrollment counter passed 100,000 students in January 2026, ABC15 broke the growth down by ZIP code. Four of the five ZIP codes adding the most ESA students were in Queen Creek and San Tan Valley. Queen Creek Unified also appeared on the list of districts with the highest share of students leaving for the ESA, alongside Dysart Unified in the West Valley, Alhambra Elementary in west Phoenix, Kingman Unified and Amphitheater Unified in Tucson.

A follow-up in March 2026, after cumulative ESA spending passed $1 billion, ranked annual growth: Queen Creek first, with three ZIP codes in the state's top 10, then the city of Maricopa, Buckeye, Goodyear and Surprise. Every one of those places is on the outer ring of the Phoenix metro. The same report found that families in ZIP codes with six-figure median incomes make up 24 percent of Arizona's children but 32 percent of ESA enrollment.

The statewide total has kept climbing. ADE's counter read 107,859 ESA students for the 2026-27 year on October 5, 2026, up from 99,709 in the April-June 2026 quarter, and ADE notes that about 7,000 renewal-eligible students had not yet submitted their paperwork. The Joint Legislative Budget Committee's baseline projected 113,602 for the full fiscal year.

Why the southeast Valley?

None of the sources above gives a single cause, so treat what follows as context rather than a verdict. Three features of the far East Valley line up with the numbers.

Young families and new houses. Queen Creek, San Tan Valley and Maricopa filled up with young families over the last decade, and new rooftops arrived faster than new school buildings of any kind.
The microschool habit. The Prenda microschool network was started by a Mesa father and still describes itself as based in Mesa. Acton Academy has an East Valley campus in Queen Creek. A microschool needs a room, a guide and a few families, which makes it the fastest option to appear in a new neighborhood.
Spending beyond tuition. ABC15's March report found that in one quarter just over half of ESA spending went to tuition and textbooks and nearly 40 percent to homeschool products and services. In places with few private campuses, families are more likely to build their own program with curriculum, tutoring and part-time studios.

It is also worth noting what changed in who applies. ABC15 reported that four in ten new ESA students had not previously been publicly funded, down from eight in ten when universal eligibility started. In other words, most new accounts now go to children leaving district or charter schools. ADE's own fourth-quarter report for fiscal 2026 put the share of new universal students in grades 1-12 who came from public school at 59.5 percent.

What a Queen Creek or San Tan Valley family should actually do

The numbers describe your neighbors. Your decision is narrower: which school, and which way to pay. A few practical points for families on the southeast edge.

Know your amount. ADE's most recent chart, an estimate for 2025-26, shows $4,718 to $6,205 for kindergarten and $7,105 to $10,540 for grades 1-12, with much higher amounts for most disability categories. The 2026-27 chart had not been posted as of this writing, so treat any precise 2026-27 figure you hear at a school open house as unofficial. Our guide to the ESA for Phoenix-area families explains how the range is set.

Ask how a microschool bills. Many programs in this part of the Valley are paid as tutoring or teaching services rather than as a school. Either can be fine, but ClassWallet wants a detailed invoice, and receipts from payment apps are not enough. Ask before the first quarter, not after. Our East Valley microschool guide lists the questions to ask.

Do not stack an STO scholarship on top. Some Gilbert and Queen Creek Christian schools have families who have relied on STO scholarships for years. An ESA parent signs a contract each year agreeing not to accept an STO scholarship for that child in the same year. If you have a large STO award at a higher-tuition school, compare the two before you switch, using our ESA vs. STO calculator.

Time the application. ESA applications are open all year. An application completed after March 31 is enrolled on or after July 1, and a new account takes about three weeks to fund once the contract is signed. For an August start, aim for winter.

Look beyond your ZIP code. The private campuses nearest Queen Creek and San Tan Valley are mostly in Gilbert, Chandler and Mesa. Our directory groups them under Gilbert, Queen Creek and San Tan Valley and Mesa and Apache Junction, and Pinal County schools have their own page.

The policy backdrop

Families in fast-growth areas sometimes ask whether the program will still be there next year. Two 2026 ballot efforts that would have changed it did not reach the November ballot: the Arizona Supreme Court left the income-cap initiative short of valid signatures and blocked a separate legislative measure on military families' funds, both on August 18, 2026. The AZTO STO has told families it expects no ballot measures and no legislative changes to the ESA for 2026-27. The program's long-term shape is a political question we will not predict, but nothing in the current calendar changes how you apply this school year.

Growth also brings scrutiny. AZPM reported in July 2026 that ADE automatically approves reimbursement requests under $2,000 because of staffing limits. That is not permission to buy something that is not allowed. Keep receipts and invoices, and check the handbook before an unusual purchase.

The southeast Valley did not become the ESA's center of gravity by accident, and the choices there will only multiply as more microschools and campuses open. Start with the amount, the school's billing, and the one-path-per-child rule, and the rest gets simpler.
