Education in Maine
Maine educates roughly 170,000 public K–12 students across about 260 School Administrative Units (SAUs) — a large number of mostly small, geographically dispersed units (regional school units, municipal school departments, and unions) reflecting Maine's rural population. Public education is overseen by the Maine Department of Education and the State Board.
Maine has one of the country's most distinctive choice mechanisms: town tuitioning, dating to 1873, which was reshaped by the 2022 U.S. Supreme Court case Carson v. Makin (which originated in Maine). Maine also mandates gifted programs, has one of the nation's strictest immunization laws, sets graduation requirements locally, and is expanding public pre-K. This guide walks through it all — for the student, the family, the school, and the educator — and points to the official source throughout.
Who must attend school
Maine requires children ages 6 to 17 to attend school (attendance may end earlier, at 15, under certain conditions). Attendance can be met through a public school, a private school approved for equivalent instruction, or a home instruction program.

Pre-K in Maine
Maine funds Public Preschool for 4-year-olds through participating SAUs and has been steadily expanding access toward broader availability (though it is not yet fully universal). For young children with disabilities, Maine's Child Development Services (CDS) provides early-intervention (birth–2) and preschool special education (ages 3–5). Maine also offers Head Start and child-care assistance.
Because public pre-K availability depends on your SAU, families should check their district's offering and enroll early. See our Kindergarten Readiness and Early Childhood toolkits.
SAUs & charters
Maine's largest districts include Portland, Lewiston, Bangor, and South Portland, but most SAUs are small — Maine has long grappled with school consolidation given its declining, dispersed student population. Maine has a small charter-school sector (capped by law at around 10 charters, overseen by the Maine Charter School Commission), plus the statewide, residential Maine School of Science and Mathematics.
Public-school choice also runs through superintendents' agreements and paying tuition to attend another SAU (with the receiving board's consent). Find Maine public and charter schools in our schools directory.
Private & independent schools in Maine
Maine's independent-school sector has an unusual feature tied to town tuitioning: several historic "town academies" are independent schools that serve as the de facto public high school for their region, accepting publicly tuitioned students:
- Town academiesIndependent (nonprofit, board-governed) schools such as Thornton Academy, Fryeburg Academy, Lincoln Academy, and Maine Central Institute — many enrolling large numbers of tuitioned students
- Independent day & boarding schoolsSchools such as Waynflete (Portland), Berwick Academy, and Kents Hill School
- Catholic & religious schoolsDiocese of Portland schools (such as the Jesuit Cheverus High School), plus other faith-based options
- Specialty schoolsMontessori and schools for specific learning needs
Maine approves independent schools that wish to receive public tuition, and accreditation is otherwise voluntary — often through the New England Association of Schools and Colleges (NEASC). Following Carson v. Makin (2022, a case that originated in Maine), religious schools may also receive town tuition. Families should ask about a school's accreditation, curriculum, and outcomes directly.
Town tuitioning & Carson v. Makin
Maine's signature choice program is town tuitioning, created in 1873 — one of only a few such systems in the country (with Vermont and New Hampshire). Because some SAUs do not operate their own public school at a given grade level, they pay tuition for their resident students to attend an approved school of the family's choice — a public school in another town, or an approved private school (in-state or out-of-state). Roughly 4,000+ students are tuitioned this way.
In 2022, the U.S. Supreme Court decided Carson v. Makin — a case originating in Maine — holding that the state cannot exclude religious ("sectarian") schools from town tuitioning simply because they are religious. As a result, public tuition funds can now flow to religiously affiliated approved schools as well (Maine added certain nondiscrimination requirements in response).
Homeschooling in Maine
Maine sits in the middle ground of homeschool regulation — more than the lightest states, less than New York or Pennsylvania. There are two pathways, and most families use home instruction:
- Notify within 10 daysFile a notice of intent to provide home instruction with your local SAU and the Maine DOE within 10 days of starting
- Continuation letterSend an annual continuation letter (by September 1 each year)
- Teach required subjectsIncluding Maine studies among the required areas
- Annual assessmentComplete a yearly assessment — a standardized test, a certified-teacher review, a local advisory-board review, or a portfolio
The alternative is operating as an equivalent private school (REPS), used less often. Maine homeschool parents set their own curriculum and (for home instruction) their own graduation approach. See our Homeschooling toolkit, and review the notice and assessment rules with the Maine DOE.
The MEA & the SAT
Maine public schools use the Maine Educational Assessment (MEA) — testing in grades 3–8 and grade 11, aligned to the Maine Learning Results — plus a science assessment. Maine also administers the SAT to high school juniors (grade 11) as its college- and career-readiness measure, at no cost to students. Maine does not require a statewide graduation exam.
Homeschooled students are not part of state testing (home-instruction families may use a standardized test to satisfy their annual assessment). See the Maine DOE assessment pages for current details.
Earning a Maine high school diploma
In keeping with its strong local-control tradition, Maine sets graduation requirements at the local level — each SAU establishes its own credit and course requirements (within required content areas such as English, mathematics, science, social studies including American history and government, fine arts, health/physical education, and Maine studies). Maine does not impose a statewide graduation exam, and while the state once mandated proficiency-based diplomas, that requirement was made optional.
- Local requirementsEach SAU sets specific credits/courses
- Required content areasIncluding Maine studies
- Proficiency-based optionalSAUs may (but need not) use proficiency-based diplomas
- No statewide examNo single test required to graduate
Special education & gifted
Maine 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 full procedural safeguards (mediation and due process). For the youngest children, Maine's statewide Child Development Services (CDS) system delivers early intervention and preschool special education.
Maine also requires gifted and talented programs: each SAU must provide a G/T program serving academically and artistically gifted students — a stronger commitment than many states. See our Special Education and Gifted & Talented toolkits, and verify with the Maine DOE.
How Maine reports school performance
Maine does not assign A–F letter grades or star ratings. Instead, it publishes school and district data through the Maine School Report Card and its federal (ESSA) accountability framework — reporting measures such as proficiency and growth on the MEA, graduation rates, English-learner progress, and school climate/opportunity indicators.
Because Maine emphasizes a data report rather than a single grade, families should read the Report Card alongside a school visit (see our Choosing the Right School toolkit). Explore Maine's school data through the Maine DOE, and find schools in our directory.
Immunizations & school entry
Maine has one of the nation's strictest school immunization laws. In 2021 (LD 798), Maine eliminated both the religious and philosophical exemptions, leaving only a medical exemption for most students. Required vaccines follow the state schedule, with additional requirements at certain grades.
Confirm current requirements with the Maine Center for Disease Control & Prevention and your school unit before enrolling.
State aid & the Alfond Grant
Maine's primary need-based program is the Maine State Grant, administered by the Finance Authority of Maine (FAME), for eligible Maine students at in-state (and some out-of-state) colleges. Maine has also invested in free community college for recent high school graduating classes. A distinctive Maine benefit is the Harold Alfond College Challenge — which automatically provides a $500 college-savings grant for every baby born a Maine resident, to seed future college saving.
Students apply by filing the FAFSA by Maine's deadline (typically May 1) and meeting program requirements. Use our Net Price, SAI Estimator, and Award Letter tools to plan costs, and see programs at FAME.
Colleges & universities in Maine
Maine's public higher education includes the University of Maine System — seven universities anchored by the flagship University of Maine (Orono) and including the University of Southern Maine — the Maine Community College System (seven colleges), and the specialized Maine Maritime Academy. Together they offer degrees from certificates through doctorates, with transfer pathways.
Maine is also home to well-known private colleges (Bowdoin, Bates, and Colby among them). Explore Maine's colleges and universities in our directory.
Becoming a teacher in Maine
Maine certifies teachers through the Maine Department of Education, and candidates must pass the required Praxis examinations after completing an approved preparation program. Maine issues certificates that advance over a career and offers alternative and conditional routes to help fill hard-to-staff and rural positions.
Maine also provides reciprocity for many out-of-state educators. See our Teacher Certification, Praxis, and Job & Interview Tips for Educators toolkits, and the Maine DOE certification pages for specifics.
