Cal. Gov. Code § 22016
For the purposes of this part, persons employed by a county superintendent of schools and whose salaries are paid from the county school service fund are county employees, except that in any county where it has been determined by the board that the office of the county superintendent of schools is a separate public agency, in which case such persons are employees of the county superintendent of schools. The cost of any elections and the employer's contribution for such employees under this part are proper charges against the county school service fund and such contribution shall be requisitioned and paid to the state as provided in Section 22550.5 of this code.
This section does not constitute a change in, but is declaratory of, preexisting law and all action heretofore taken by a county board of supervisors for coverage under the federal system of employees of the county superintendent of schools whose salaries are paid from the county school service fund, in accordance with state and federal law, is hereby ratified, confirmed and validated.
