Cal. Health and Safety Code § 1596.656

(a) A person 18 years of age or older, who provides child care or child care supervision in an ancillary day care center, as defined in Section 1596.60, shall be registered pursuant to Sections 1596.603 and 1596.605. Nothing in this chapter shall be construed to prevent a person under 18 years of age from being employed in an ancillary day care center. (b) Notwithstanding any provision of law to the contrary, if a person 18 years of age or older is denied trustline registration by the department pursuant to Section 1596.605 or 1596.607, or if the department revokes a person’s trustline registration pursuant to Section 1596.608, that person shall be ineligible for employment in a position providing child care or child care supervision in an ancillary day care center. (c) If an existing employee providing child care or child care supervision in an ancillary day care center, or a prospective employee seeking employment in a position that provides child care or child care supervision in an ancillary day care center, submits an application to the department to become a registered trustline child care provider, that existing or prospective employee shall be deemed to be in compliance with the requirements of this section and permitted to work in a position providing child care or child care supervision pending the department’s review of his or her trustline application. The existing or prospective employee shall become ineligible for employment providing child care or child care supervision in an ancillary day care center if the department denies his or her trustline application and any right to appeal the department’s denial has been exhausted or has expired. (d) This section shall become operative on January 1, 2011.
