Cal. Ed. Code § 1259
The Director of Corrections may establish and maintain classes for inmates of institutions or facilities under the jurisdiction of the Department of Corrections by entering into an agreement with the county superintendent of schools of a county in which the institution or facility is located, or of a county contiguous to such county, with the approval of the county board of education, under which the county shall maintain classes for such inmates.
Any agreement entered into between the county superintendent of schools and the Director of Corrections, pursuant to this section shall require the Department of Corrections to reimburse the county for the cost to the county of maintaining such classes. "Cost" as used herein includes contributions required to be made by the county superintendent to the State Teachers' Retirement System, but such cost shall not include an amount in excess of the amount expended by the superintendent for salaries of the teachers for such classes, increased by one-fifth. Salaries of such teachers for the purposes of this section shall not exceed the salaries as set by the county superintendent for teachers in other classes for adults maintained by the county.
Attendance or average daily attendance in classes established pursuant to this section shall not be reported to the State Department of Education or the Board of Governors of the California Community Colleges for apportionment and no apportionment from the State School Fund shall be made on account of average daily attendance in such classes.
No county superintendent of schools shall provide for the academic education of adult inmates of state institutions or facilities under the jurisdiction of the Department of Corrections except in accordance with this section.
