Cal. Bus. & Prof. Code § 4531
The course of instruction of an approved school shall consist of not less than the number of hours or semester units of instruction required for the other program administered by the board. The subjects of instruction shall include the principles of the care of the mentally disabled and the developmentally disabled. Clinical inpatient experience shall be an integral part of that prescribed or equivalent course of study and training. The experience shall be obtained in a state hospital, except where the board finds that the requirement is not feasible due either to the distance of a state hospital from the school or the unavailability, as determined by the State Department of Developmental Services or the State Department of State Hospitals, of state hospital clinical training placements.
