Timeline for Implementation

California Assembly Bill 130 (which modifies EC Section 48000) outlines the required average ratio of adults to children in the transitional kindergarten classroom. Each classroom must be taught by a teacher who holds a credential issued by the state Commission on Teacher Credentialing (see Ed Code 44065 and 44256 for additional information). Starting in the 2022-23 school year, the average ratio in the classroom is one adult per every 12 students. In 2023-24, the average ratio is one adult per every 10 students contingent upon an appropriation of funds for this purpose. Additionally, school districts and charter schools must maintain an average transitional kindergarten class enrollment of not more than 24 pupils per classroom for each school site.
