Education in Illinois
Illinois educates roughly 1.9 million public K–12 students across a remarkably large number of districts — about 850, including many small elementary-only and high-school-only districts, plus Chicago Public Schools, the nation's fourth-largest district. The system is overseen by the Illinois State Board of Education (ISBE) and a State Superintendent.
A few things distinguish Illinois. It was the first state to require FAFSA completion to graduate. It currently has limited private-school choice — its tax-credit scholarship program expired at the end of 2023. It has one of the country's most flexible homeschool frameworks (homeschools are legally private schools), and it's expanding toward universal preschool. 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
Illinois requires children ages 6 to 17 to attend school — a child who is 6 by September 1 is of compulsory age, and the requirement ends at 17 (or upon high school graduation). Attendance can be met through a public school, a private or parochial school, or homeschooling (which Illinois treats as a private school).

Preschool for All & Smart Start
Illinois funds Preschool for All (PFA) — state-funded preschool for 3- and 4-year-olds, prioritized for children who are at-risk or from lower-income families. Through the Smart Start Illinois initiative, the state is expanding toward preschool access for every 3- and 4-year-old whose family wants it, adding thousands of new seats, and has created a new Illinois Department of Early Childhood to coordinate early-learning programs.
Illinois also offers Head Start and the Child Care Assistance Program for eligible families. Availability is growing but not yet fully universal, so families should apply early. See our Kindergarten Readiness and Early Childhood toolkits.
Districts & charters
Illinois's ~850 districts are unusually varied — some serve only elementary grades, some only high school, and some are unit (K–12) districts. By far the largest is Chicago Public Schools (CPS), followed by suburban districts around Chicago and downstate systems in Rockford, Aurora, Springfield, and elsewhere. Illinois has a charter-school sector concentrated in Chicago; statewide, charter growth is relatively limited.
Within CPS, families have extensive choice through magnet schools, selective-enrollment high schools, and other options (via the GoCPS application). Elsewhere, options are more limited. Find Illinois public and charter schools in our schools directory.
Private & independent schools in Illinois
Illinois has a large private-school sector, concentrated in the Chicago area, spanning:
- Catholic & parochial schoolsThe Archdiocese of Chicago runs one of the country's largest Catholic school systems, alongside downstate dioceses — with schools such as Loyola Academy, St. Ignatius, and Fenwick
- Independent schoolsNonprofit, board-governed schools such as the University of Chicago Laboratory Schools, the Latin School of Chicago, Francis W. Parker School, and North Shore Country Day
- Other religious schoolsA strong Lutheran (LCMS) network, plus Jewish, Christian, and other faith-based schools
- Specialty schoolsMontessori, Waldorf, and schools for specific learning needs
Illinois regulates private schools only lightly (state recognition is optional), and accreditation is voluntary — many independent schools belong to the Chicago-based Independent Schools Association of the Central States (ISACS) or the Lake Michigan Association of Independent Schools, or are accredited through Cognia. Note that Illinois's Invest in Kids tax-credit scholarship expired at the end of 2023, so private schools are again funded by tuition and their own financial aid. Families should ask about a school's accreditation, curriculum, and outcomes directly.
How choice works in Illinois
Illinois currently offers relatively limited school choice, especially on the private side. Its tax-credit scholarship program, the Invest in Kids Act, expired at the end of 2023 and was not renewed — so there is no statewide private-school voucher, ESA, or scholarship program at this time. Public options include:
- Charter schoolsAvailable mainly in Chicago; a limited statewide sector
- Magnet & selective schoolsExtensive within Chicago (GoCPS); fewer elsewhere
- Limited open enrollmentIllinois has no broad statewide inter-district open enrollment
- HomeschoolingA very flexible option (below)
Illinois does offer a modest $750 education-expense tax credit for K–12 costs (see Homeschooling). See our School Types toolkit for how these options compare.
Homeschooling in Illinois
Illinois is one of the most homeschool-friendly states in the country. Under Illinois law (105 ILCS 5/26-1) and the landmark 1950 case People v. Levisen, homeschools are legally private schools — which means minimal requirements and broad autonomy:
- No registrationNo notification, registration, or approval to begin
- No testingNo standardized testing or state evaluation required
- No hour/day minimumsNo statutory number of days or hours (public schools' ~176–180 days is a common benchmark, not a legal floor)
- Teach the branchesCover the required subjects — including language arts, math, science, social science, fine arts, and health — in English
Illinois homeschool families set their own curriculum, schedule, and graduation requirements and issue their own diplomas. Illinois also offers a modest $750 K–12 education-expense tax credit (for eligible costs like lab/book-rental fees and tuition, via Schedule ICR). Note that access to public-school sports is not guaranteed statewide and varies by district. See our Homeschooling toolkit, and review 105 ILCS 5/26-1 via the ISBE.
IAR, ISA & the SAT
Illinois public schools use the Illinois Assessment of Readiness (IAR) in English language arts and mathematics in grades 3–8, the Illinois Science Assessment (ISA) in grades 5, 8, and 11, and the SAT in grade 11 (Illinois uses the SAT as its high school accountability test, offered free during the school day). Kindergartners are assessed with the KIDS (Kindergarten Individual Development Survey).
Homeschooled students do not take the IAR (it's for enrolled public-school students), though college-bound homeschoolers can register for the SAT or ACT independently. See the ISBE assessment pages for current details.
Earning an Illinois high school diploma
Illinois sets statewide minimum course requirements for graduation but leaves districts to set specific credit totals, so exactly what it takes to graduate varies by district. The state minimums generally include 4 years of English/language arts, 3 of mathematics, 2 of science, 2 of social studies (including U.S. history and civics), and additional courses in areas such as writing, the arts or a world language, and consumer education. A distinctive Illinois requirement: seniors (and their families) must complete the FAFSA (or a nonparticipation waiver) — Illinois was the first state to make this a graduation requirement.
- State minimums + local creditsDistricts set the specific totals
- FAFSA requirementComplete the FAFSA or opt out — a first-in-the-nation rule
- CivicsA required civics course
- No exit examNo single test is required to graduate
Special education & gifted
Illinois 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 ISBE and full procedural safeguards (mediation and due process). In Chicago and larger districts, special-education services are extensive; families statewide have the same federal rights.
On gifted education, Illinois has an Accelerated Placement Act requiring districts to adopt acceleration policies (for early entrance, subject or grade acceleration), but Illinois does not robustly fund or mandate gifted programs statewide — so dedicated gifted programming varies widely by district. See our Special Education and Gifted & Talented toolkits, and verify with the ISBE.
Illinois school designations & report card
Rather than assigning A–F letter grades, Illinois assigns each school a summative designation — historically Exemplary, Commendable, Targeted, or Comprehensive — based on multiple measures (achievement and growth, graduation and attendance, English-learner progress, and more), all published in the detailed Illinois Report Card. (Illinois has been updating this accountability framework, so the labels and criteria are evolving.)
The Report Card is a rich starting point, not the whole story — visit schools and look deeper (see our Choosing the Right School toolkit). Explore the Illinois Report Card, and find schools in our directory.
Immunizations & school entry
To enroll in an Illinois school, students must show proof of required immunizations per the schedule set by the Illinois Department of Public Health, along with health examinations (and, at certain grades, eye and dental exams). Additional requirements apply at certain grades (including 6th- and 12th-grade entry).
Illinois allows medical exemptions and religious exemptions (via a signed Certificate of Religious Exemption) — it does not offer a broad personal-belief/philosophical exemption. Confirm current requirements with the Illinois Department of Public Health and your school district before enrolling.
The MAP grant & state aid
Illinois's largest state financial-aid program is the Monetary Award Program (MAP) grant — need-based grants for eligible Illinois students attending in-state colleges and universities. Illinois also offers AIM HIGH (merit-based grants awarded through public universities) and other programs. These are administered by the Illinois Student Assistance Commission (ISAC).
Students apply by filing the FAFSA (or the Alternative Application for Illinois Financial Aid) — and because MAP funds are limited, applying early matters. Use our Net Price, SAI Estimator, and Award Letter tools to plan costs, and see programs at isac.org.
Colleges & universities in Illinois
Illinois has twelve public universities, anchored by the University of Illinois System — the flagship University of Illinois Urbana-Champaign, the University of Illinois Chicago (UIC), and the University of Illinois Springfield (UIS) — along with Illinois State, Northern Illinois, Southern Illinois, and others. The Illinois Community College System comprises 48 community colleges, offering associate degrees, workforce training, and strong transfer pathways.
Illinois is also home to many private institutions (Northwestern, the University of Chicago, DePaul, Loyola, and more). Explore Illinois's colleges and universities in our directory.
Becoming a teacher in Illinois
Illinois licenses teachers through the ISBE, issuing the Professional Educator License (PEL). Unlike Praxis states, Illinois uses the Illinois Licensure Testing System (ILTS) — Illinois-specific content-area tests — after an approved preparation program (Illinois recently made the edTPA teaching performance assessment optional). Candidates apply through the ELIS online system.
Illinois offers alternative-licensure routes for career changers and reciprocity for many out-of-state educators. See our Teacher Certification, Praxis, and Job & Interview Tips for Educators toolkits, and the ISBE licensure pages for specifics.
