No high school or unified school district shall report for state apportionments average daily attendance in classes: (1) if the district receives full compensation for such class from any public or private agency, individual or group of individuals, except fees authorized by Section 52612; or (2) if such classes are not located in facilities clearly identified in such a manner, and established by appropriate procedures, to insure that attendance in such classes is open to the general public, except those authorized pursuant to Section 52570 and those in state hospitals. The State Board of Education may adopt such regulations as may be necessary to enforce this section.
