The governing board of a school district or private school may enter into such an agreement regardless of whether the institution or facility at which the classes are to be established and maintained is within or without the boundaries of the school district.

Salaries of such teachers for the purposes of this section shall not exceed the salaries as set by the governing board for teachers in other classes for adults maintained by the district, or private schools. (c) Attendance or average daily attendance in classes established pursuant to this section or in classes in trade and industrial education or vocational training for adult inmates of institutions or facilities under the jurisdiction of the Department of Corrections and Rehabilitation shall not be reported to the State Department of Education for apportionment and no apportionment from the State School Fund shall be made on account of average daily attendance in such classes. (d) No school district or private school shall provide for the academic education of adult inmates of state institutions or facilities under the jurisdiction of the Department of Corrections and Rehabilitation except in accordance with this section.
