California preschool: Credential & training requirements
Director / Operator requirements
Private preschools operating under a California childcare center license require a director meeting California Department of Social Services’s qualification standards under Title 22, Division 12 (Health and Safety Code). Requirements typically include ECE coursework, administrative experience, and background clearance. Some states require a specific director credential or permit for programs serving preschool-age children.
Teacher / Caregiver requirements
Preschool lead teachers in California must meet minimum education requirements set by California Department of Social Services. Most states require at minimum a CDA credential or equivalent ECE college coursework for preschool teachers. Contact California Department of Social Services for the current teacher qualification standard, as requirements may differ between privately licensed and state-funded programs.
Annual training requirements
All preschool staff at California-licensed programs must complete continuing education hours annually. CPR and pediatric first aid are required for all direct-care staff. State-funded programs may have additional professional development requirements tied to their funding contract.
