Decide to home school your child in Oklahoma. Oklahoma statutes state that children older than 5 but under 18 must attend a public or private school unless some other form of education is provided by the parents. According to the Home School Legal Defense Association, "other form of education" is interpreted to include home school.
Provide your children with 180 days per year of educational instruction comparable to what the public school system offers. The number of instructional days is part of the home school law. Oklahoma State Standards for each grade level are available from the Oklahoma Department of Education.
Join a state or local home school support group. This is not required, but it will help you to have other home school families to socialize with. Many home school support groups offer classes and co-ops for their members.
