In the case of attendance upon private school, exemption from the requirements of attendance upon compulsory continuation education 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.
