Understand that the Oklahoma state constitution protects parents' right to home-school their children. The wording allows for "other means" of schooling outside of public or private school instruction. This wording was specifically placed in the constitution with the intent to protect a parent's right to home-school his child. There are no parental-education requirements whatsoever to teach your own child in your own home.
Because of the wording of the Oklahoma state constitution, there is no paperwork required at all to start home-schooling a child. You don't have notify a person or agency, and you do not have to maintain records of your child's home schooling.
The compulsory school attendance age in Oklahoma begins at age of 5, so you should teach kindergarten if you home-school.
No testing requirements exist for home-schooled children in Oklahoma. The courts have ruled that any such monitoring is not lawful according to Oklahoma's laws.
This state works on the assumption that parents have the right to make all educational decisions for their child. There are no official curriculum requirements, although the courts have indicated that a comparable education should be taking place at home as the one that is offered in a public school. Suggested subjects would include science, social studies, math and language arts.
If any child's education comes under question, the burden of proving that the provided education is not sufficient is placed upon the state. If a parent is found to be teaching the basic subjects for about 180 days a year, then there is nothing more that will be asked of that particular home school. However, home schooling cannot be used as an excuse to allow a child to be truant.
