(1) Existing law requires a pupil to complete designated coursework while in grades 9 to 12, inclusive, in order to receive a diploma of graduation from high school. These graduation requirements include, among others, the completion of 3 years of courses in English and 3 years of courses in social studies, including one-year courses in United States history and geography and world history, culture, and geography, a one-semester course in American government and civics, and a one-semester course in economics. Existing law requires the Instructional Quality Commission to develop, and the State Board of Education to adopt, modify, or revise, a model curriculum in ethnic studies. Existing law also encourages each school district and charter school that maintains any of grades 9 to 12, inclusive, and that does not otherwise offer a standards-based ethnic studies curriculum to offer, beginning in the school year following the adoption of the model curriculum, a course of study in ethnic studies based on the model curriculum. This bill would add the completion of a one-semester course in ethnic studies, meeting specified requirements, to the graduation requirements commencing with pupils graduating in the 2029–30 school year, including for pupils enrolled in a charter school. The bill would expressly authorize local educational agencies, including charter schools, to require a full-year course in ethnic studies at their discretion. The bill would require local educational agencies, including charter schools, to offer an ethnic studies course commencing with the 2025–26 school year, as specified. The bill would authorize, subject to the course offerings of a local educational agency, including a charter school, a pupil to satisfy the ethnic studies course requirement by completing either (A) a course based on the model curriculum in ethnic studies developed by the commission, (B) an existing ethnic studies course, (C) an ethnic studies course taught as part of a course that has been approved as meeting the A–G requirements of the University of California and the California State University, or (D) a locally developed ethnic studies course approved by the governing board of the school district or the governing body of the charter school. The bill would prohibit a course that does not use ethnic studies content as the primary content through which the subject is taught from being used to satisfy the ethnic studies course requirement. The bill would require a pupil who completes a course described above to also accrue credit for coursework in the subject that the course is offered, including, if applicable, credit towards satisfying a course required for a diploma of graduation from high school. These provisions would become operative only upon an appropriation of funds by the Legislature for these purposes in the annual Budget Act or another statute. Because the bill would add new duties to local educational agencies, it would constitute a state-mandated local program. (2) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.
