In December of 2024, the California Department of Education (CDE) released Management Bulletin (MB) 23-10, which provides guidance to California State Preschool Program (CSPP) contractors of the requirements to phase in implementation of the Classroom Assessment Scoring System (CLASS®) and the CLASS® Environment Tool. In order to strengthen teacher-child interactions and support quality improvement, this MB also preserves certain environmental requirements for CSPP, that were formerly included in the ERS and not included in either CLASS, CLASS Environment, or licensing/license-exempt regulations.

To support the implementation of 23-10 and the CLASS tool, CDE announced the ASPIRE (Achieving Success in Positive Interactions, Relationships, and Environments) program in April of 2024.
