How the funding fits
$7,105–$10,540
Every Arizona K-12 student can open an Empowerment Scholarship Account. For the grades International School of Arizona serves, ADE's latest chart gives $4,718–$6,205 (K) and $7,105–$10,540 (grades 1-12); that chart is labeled 2025-26 (ADE estimate; the 2026-27 chart isn't posted yet), and the exact figure depends on grade and the funding formula for the school the child would otherwise attend. The account can pay tuition at a qualified private school that is set up as a ClassWallet vendor. The state keeps no list of schools that take ESA payments, so ask International School of Arizona directly.
Takes STO scholarships from: APESF, APSTO, IBE (per each STO's published school list, Oct 2026). Each STO decides its own awards, so apply to every one on this list that fits; appearing on a list is not a promise of money. Remember that a child on an ESA contract cannot take an STO scholarship that same year, so this is a choice, not an extra.
Independent schools in the Phoenix area usually run their own need-based aid with a winter deadline, separate from any ESA or STO funding.
