Cal. Educ. Code § 44837

Governing boards of school districts shall not employ or retain in employment any person in public school service who has been determined to be a sexual psychopath under the provisions of Article 1 (commencing with Section 6300), Chapter 2, Part 2, Division 6 of the Welfare and Institutions Code or under similar provisions of law of any other state. If, however, such determination is reversed and the person is determined not to be a sexual psychopath in a new proceeding or the proceeding to determine whether he is a sexual psychopath is dismissed, this section does not prohibit his employment thereafter.
