Existing law requires the State Board of Education to adopt at least 5 basic instructional materials in specified subject areas, including, among others, social science, for use in kindergarten and grades 1 to 8, inclusive, as specified. Existing law establishes the Instructional Quality Commission, as specified, and requires the commission to, among other things, develop criteria for evaluating instructional materials. This bill would require the commission, when the state board adopts new instructional materials for history-social science on or after January 1, 2025, to consider providing for inclusion, in its evaluation criteria, content on the case of Mendez v. Westminster School District of Orange County. This bill would incorporate additional changes to Section 51226.3 of the Education Code proposed by AB 1821 to be operative only if this bill and AB 1821 are enacted and this bill is enacted last.
