In a show of support for science and child health, California Governor Gavin Newsom has signed Senate Bill 328 (SB 328) into law. The bill, introduced by Senator Anthony Portantino, was passed by the state legislature and sent to Governor Newsom for approval. Under this new law, California’s middle schools can start required classes no earlier than 8:00 a.m. and high schools no earlier than 8:30 a.m. Specific scheduling within those parameters is left to local school districts, with allowances made for some rural communities. The guidelines go into effect in the 2022 school year for most districts.
