Education in Arizona
Arizona educates roughly 1.1 million public K–12 students across about 200 school districts — plus one of the largest charter-school sectors in the nation, where roughly one in five public-school students attend a charter. Public education is overseen by the Arizona Department of Education (ADE), the elected Superintendent of Public Instruction, and the State Board of Education.
Arizona is a national epicenter of school choice: it pioneered charter schools in the 1990s and, in 2022, became the first state with a truly universal ESA (Empowerment Scholarship Account) program. Combined with broad open enrollment and a very homeschool-friendly framework, Arizona offers families an unusually wide menu of options. This guide walks through all of it — for the student, the family, the school, and the educator — and points to the official source throughout.
Who must attend school
In Arizona, children must attend school from age 6 to age 16. Attendance can be met through a public district school, a charter school, a private school, or homeschooling (below). Arizona also allows families, when homeschooling, to delay formal instruction until age 8 by noting it on the homeschool affidavit.
- Start age6 years old
- End of compulsory age16
- OptionsDistrict, charter, private, or homeschool
- Delay optionHomeschoolers may delay instruction to age 8
Pre-K in Arizona
Arizona does not offer a universal state prekindergarten program; publicly funded early education is targeted and varies by community. A key player is First Things First — a statewide early-childhood agency (funded largely by a tobacco tax) that supports quality early learning, preschool scholarships in some areas, and family programs. Head Start serves eligible children, alongside private preschools and child care.
Availability and cost vary widely, so families should check local options early. Notably, preschool-age children with an IEP or 504 plan may qualify for ESA funding (below). See our Kindergarten Readiness and Early Childhood toolkits.
Districts, charters & open enrollment
Arizona's public system combines about 200 school districts with a very large charter-school sector — Arizona has more charter students per capita than almost any state. The largest districts are concentrated in metro Phoenix and Tucson — Mesa, Chandler, Gilbert, Deer Valley, Tucson Unified, and others.
Arizona also has broad open enrollment: families may apply to attend almost any public district or charter school with available space, in or out of their home area — one of the more expansive public-choice frameworks in the country. Charters are authorized primarily by the Arizona State Board for Charter Schools. Find Arizona public and charter schools in our schools directory.
Private & independent schools in Arizona
Arizona has a large and fast-growing private-school sector — expanded further by its universal ESA and tax-credit scholarships — spanning several kinds of schools:
- Catholic & parochial schoolsDiocese of Phoenix and Diocese of Tucson schools (such as Brophy College Preparatory, Xavier College Preparatory, and Salpointe Catholic)
- Independent schoolsNonprofit, board-governed schools such as Phoenix Country Day School, All Saints' Episcopal, and Green Fields
- Other religious & Christian schoolsA wide range of Christian and faith-based options
- Microschools & specialty schoolsArizona has a booming microschool sector (many funded through ESAs), plus Montessori and Waldorf programs
Arizona does not license or accredit private schools, so accreditation is voluntary — many independent schools are accredited through the Independent Schools Association of the Southwest (ISAS) or Cognia. Because Arizona's ESA and tax-credit programs fund private-school tuition, participating schools take on some requirements. Families should ask about a school's accreditation, curriculum, and outcomes directly.
The universal ESA & tax-credit scholarships
Arizona's landmark program is the Empowerment Scholarship Account (ESA) — the nation's first universal education savings account. Since September 2022, essentially every Arizona K–12 student qualifies (no lottery, no waitlist, and no income test for the universal category), and the program has grown to well over 100,000 participants. Key facts:
- Funding amountMost students receive ~90% of the state per-pupil base — typically $7,000–$8,000/year (less for kindergarten; more for disabilities)
- Administered by ADEFunds are managed through ClassWallet
- Broad approved usesPrivate-school tuition, curriculum, tutoring, therapies, and more
- Trade-offsESA students generally can't also attend public/charter school or receive an STO scholarship, and must file quarterly expense reports
Arizona also has long-standing tax-credit scholarships through School Tuition Organizations (STOs) — funded by individual and corporate tax credits — for private-school tuition. Together with charters and open enrollment, these make Arizona one of the most choice-rich states in the nation.
Homeschooling in Arizona
Arizona is consistently ranked among the most homeschool-friendly states, with refreshingly minimal requirements. To homeschool traditionally, you:
- File one affidavitA notarized affidavit of intent with your county school superintendent within 30 days of starting (with proof of the child's birth) — a one-time filing, not an annual renewal
- Teach five subjectsReading, grammar, mathematics, science, and social studies
- No testing or oversightNo standardized testing, minimum hours/days, curriculum approval, record submission, or parent qualifications
- Sports accessHomeschoolers may join public-school sports & activities (Arizona's "Tim Tebow" law)
An important distinction: the ESA path is separate from traditional homeschooling. ESA participants are legally classified as receiving "nonpublic instruction" (they sign an ESA contract rather than file a homeschool affidavit) and must follow ESA rules — using ClassWallet and documenting expenses — in exchange for the funding. Families choose one path or the other. See our Homeschooling toolkit, and confirm details with the ADE.
AASA, AzSCI & the ACT
Arizona public schools use AASA (Arizona's Academic Standards Assessment) — the statewide summative test in English language arts and mathematics in grades 3–8 (AASA replaced the earlier AzMERIT/AzM2 assessments). Science is assessed through AzSCI at designated grades, and Arizona uses the ACT as its statewide high school assessment.
Homeschooled and ESA students are generally not part of statewide testing (traditional homeschoolers face no testing requirement). See the ADE assessment pages for current details.
Earning an Arizona high school diploma
The Arizona State Board sets 22 credits as the minimum for a high school diploma (Ariz. Admin. Code R7-2-302), generally including 4 English, 4 mathematics (through Algebra II or an approved equivalent), 3 science, 3 history and social science (including Arizona history, world history/geography, government, and economics), and electives. Districts and charters may add requirements.
Arizona also has a distinctive civics test requirement: students must pass a test identical to the civics portion of the U.S. naturalization exam. Beginning with the class of 2026, the passing score rose to 70 out of 100 (it was 60 through 2025).
- Minimum credits22 credits statewide
- Civics testNow 70/100 to pass (class of 2026 onward)
- Personal CurriculumSome math requirements may be modified via a Personal Curriculum
- Local additionsDistricts/charters may require more
Special education & gifted
Arizona serves students with disabilities under the federal IDEA, providing eligible students a free appropriate public education through an IEP in the least restrictive environment, with oversight from ADE's Exceptional Student Services (ESS) and full procedural safeguards (mediation, state complaint, and due process). Students with disabilities also receive enhanced ESA funding if they choose that path.
Notably, Arizona mandates gifted education: state law (A.R.S. § 15-779) requires school districts to identify and provide appropriate services (a scope and sequence) for gifted students. See our Special Education and Gifted & Talented toolkits, and verify with ADE Exceptional Student Services.
Arizona A–F school letter grades
Arizona assigns public schools an annual A–F letter grade (A.R.S. § 15-241), giving families an at-a-glance signal based on measures such as student proficiency, academic growth, graduation rate, college and career readiness, and English-learner progress. Because growth counts heavily, the grade reflects more than raw test scores.
A letter grade is a helpful starting point, not the whole story — visit schools and look deeper (see our Choosing the Right School toolkit). Explore Arizona school letter grades and report cards through the ADE, and find schools in our directory.
Immunizations & school entry
To enroll in an Arizona school, students must show proof of required immunizations per the schedule set by the Arizona Department of Health Services, or a valid exemption. Requirements follow the state schedule, with additional doses required at certain grades (including 7th grade).
Arizona allows medical exemptions and — more broadly than many states — a personal-belief (personal exemption) for immunizations, via the state exemption form. Confirm current requirements with the Arizona Department of Health Services and your school district before enrolling.
The Arizona Promise Program & state aid
Arizona's signature state college-aid program is the Arizona Promise Program — a "last-dollar" grant that covers tuition and mandatory fees at Arizona's three public universities (ASU, UA, and NAU) for eligible Pell-eligible Arizona resident students who enroll full-time straight out of an Arizona high school. Arizona also offers the Arizona Teachers Academy (tuition support for future teachers who commit to teaching in Arizona).
Students apply by filing the FAFSA and enrolling at a participating institution. Arizona's public universities and community colleges also offer many institutional scholarships. Use our Net Price, SAI Estimator, and Award Letter tools to plan costs, and see current programs via the Arizona Board of Regents.
Colleges & universities in Arizona
Arizona's public universities — Arizona State University (ASU), the University of Arizona (UA), and Northern Arizona University (NAU) — are governed by the Arizona Board of Regents (ABOR); ASU is among the largest universities in the country. On the two-year side, the Maricopa Community Colleges (ten colleges across metro Phoenix) form one of the nation's largest community-college systems, joined by Pima, Central Arizona, and other districts, all offering associate degrees and strong transfer pathways.
Arizona also has private and tribal colleges. Explore Arizona's colleges and universities in our directory.
Becoming a teacher in Arizona
Arizona certifies teachers through the ADE, and candidates take the National Evaluation Series (NES) exams (which replaced Arizona's former AEPA tests) for their subject and, as applicable, professional knowledge — not the Praxis. Arizona is known for offering flexible and alternative pathways into teaching, including routes for subject-matter experts and career changers, alongside traditional preparation programs.
Arizona issues standard and specialized certificates, requires ongoing renewal, and offers reciprocity for many out-of-state educators. See our Teacher Certification, Praxis, and Job & Interview Tips for Educators toolkits, and the ADE Certification pages for specifics.
