The Fair Education Act adds lesbian, gay, bisexual and transgender Americans, as well as people with disabilities, to existing state law that requires that the contributions of women and minorities be taught in California social science classes. It also prohibits materials that reflect adversely on people because of race, gender or other characteristics.

The law officially took effect Jan. 1. But the California Department of Education hasn’t laid out a companion curriculum, and state officials say they are leaving it up to school districts to determine how to comply.
