Cal. Ed. Code § 48222
Children who are being instructed in a private full-time day school by persons capable of teaching shall be exempted. Such school shall, except under the circumstances described in Section 30, be taught in the English language and shall offer instruction in the several branches of study required to be taught in the public schools of the state. The attendance of the pupils shall be kept by private school authorities in a register, and the record of attendance shall indicate clearly every absence of the pupil from school for a half day or more during each day that school is maintained during the year.
Exemptions under this section shall be valid only after verification by the attendance supervisor of the district, or other person designated by the board of education, that the private school has complied with the provisions of Section 33190 requiring the annual filing by the owner or other head of a private school of an affidavit or statement of prescribed information with the Superintendent of Public Instruction. The verification required by this section shall not be construed as an evaluation, recognition, approval, or endorsement of any private school or course.
