What units do you need to teach private preschool in California state?

To teach preschool privately in California, you don't need specific "units" in the sense of college course units. Instead, you need to meet specific licensing requirements set by the California Department of Education (CDE), which focuses on qualifications and training, not necessarily a specific number of college credits.

The requirements depend on the type of preschool program you want to operate:

* Family Child Care Homes: These smaller programs usually require a minimum number of hours of training from a state-approved provider. The exact number of hours varies and may depend on the number of children cared for. They also require background checks and health screenings.

* Preschools (larger programs): These require a director with specific qualifications, which often include a higher level of education and experience than family child care homes. The director will need to meet specific requirements, and teachers may also need specific training and qualifications, though the specifics again vary depending on the program size and age group served.

In short: There's no set number of "units" or college credits. You need to meet the specific licensing requirements outlined by the California Department of Education, which emphasize training, experience, and background checks relevant to child care. Contact the California Department of Education or your local licensing agency to get the precise and up-to-date requirements for your specific situation.
