Home instruction must be provided for 'the full term the schools of the district are in session' under 70 O.S.

Oklahoma is the least-regulated homeschool state and the only one with a constitutional homeschool guarantee (Okla. Const. Art. XIII, Sec. 4: the Legislature shall provide for compulsory attendance 'unless other means of education are provided'). Compulsory school age is 5-18 (70 O.S. Sec. 10-105). Parents satisfy the law by providing 'other means of education' in good faith for the full school term (~180 days). There is NO notification, NO required subject list enforced, NO required testing/assessment, NO required recordkeeping, NO teacher-qualification requirement, and NO state oversight or tracking of homeschoolers. Home-educated students are not subject to the state's public-school graduation-credit requirements; parents issue their own diplomas.

No notification, registration, or approval is required. Oklahoma does not require parents to notify the state, school district, or any authority before or while homeschooling. There is no form to file. (HSLDA: 'No notice'; CRHE: 'no oversight'.) Oklahoma is the only state with a constitutional guarantee of the right to homeschool (Okla. Const. Art. XIII, Sec. 4), and the compulsory-attendance statute (70 O.S. Sec. 10-105) explicitly permits 'other means of education.'

No recordkeeping required by law. Oklahoma does not require home educators to retain academic records or submit proof of child identity (CRHE). Maintaining records (attendance, work samples, a transcript) is strongly recommended as a best practice for future enrollment, but it is not legally mandated.

  • None mandated by statute. Oklahoma law does not require home educators to teach any specific subjects (CRHE confirms 'does not require home educators to teach any specific subjects, including core subjects like math and reading'). Note: 70 O.S. Sec. 11-103.6 requires reading instruction generally, and case law references instruction 'equivalent in fact' to public school, but no enumerated subject list is enforced for homeschoolers.

Is homeschooling legal in Oklahoma?
Yes. Oklahoma is the least-regulated homeschool state and the only one with a constitutional homeschool guarantee (Okla.
Do I have to notify anyone to homeschool in Oklahoma?
No. Oklahoma does not require parents to file a notice to begin homeschooling. No notification, registration, or approval is required. Oklahoma does not require parents to notify the state, school district, or any authority before or while homeschooling. There is no form to file. (HSLDA: 'No notice'; CRHE: 'no oversight'.) Oklahoma is the only state with a constitutional guarantee of the right to homeschool (Okla. Const. Art. XIII, Sec. 4), and the compulsory-attendance statute (70 O.S. Sec. 10-105) explicitly permits 'other means of education.'
Is standardized testing required for homeschoolers in Oklahoma?
No annual test is mandated for homeschoolers in Oklahoma. The state test (OSTP (Oklahoma School Testing Program) — ELA, Mathematics, and Science in grades 3-8; high school CCRA assessments plus a Grade 11 U.S. History test) is not required for home-educated students.
What subjects are required for homeschooling in Oklahoma?
Oklahoma requires instruction in: None mandated by statute. Oklahoma law does not require home educators to teach any specific subjects (CRHE confirms 'does not require home educators to teach any specific subjects, including core subjects like math and reading'). Note: 70 O.S. Sec. 11-103.6 requires reading instruction generally, and case law references instruction 'equivalent in fact' to public school, but no enumerated subject list is enforced for homeschoolers..
Does Oklahoma have its own learning standards?
Math: Oklahoma Academic Standards for Mathematics (OAS-M), 2022 revision (originally adopted 2016, replacing Common Core which Oklahoma repealed in 2014). ELA: Oklahoma Academic Standards for English Language Arts (OAS-ELA), 2021 revision (revision of the 2016 OAS-ELA which replaced Common Core). Science: Oklahoma Academic Standards for Science (OAS-S), 2020 revision. NGSS-informed and three-dimensional in structure, but Oklahoma-specific (not a verbatim adoption of NGSS); a further 2026 revision is in progress.. Social studies: Oklahoma Academic Standards for Social Studies (OAS), 2019 revision. State-specific; loosely informed by the national C3 Framework but Oklahoma-authored. (A new 2025 revision has been adopted and is being phased in.).
