What are your options?

Private school affidavit

Parents or Legal Guardians choosing to homeschool entirely on their own should fill out a private school affidavit. Parents are not required to report to their school district. However, keeping in mind that the school district has responsibility for checking on school-age children not attending school, you might avoid confusion by informing the district that you intend to home school or privately educate your children. In addition, many public schools will require that you provide proof of filing an affidavit prior to withdrawing your child from their public school. (CA Dept. of Ed.)

Independent Study

Independent study is a different way of learning. In independent study, a student is guided by a teacher but usually does not take classes with other students every day. The student works independently. (CA Dept. of Ed)

Charter Schools

There are many public charter schools that offer more flexibility for students and parents and some that cater to those who are focusing on home-based instruction. (CA Dept. of Ed.)
