​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.

A consensus letter has been forwarded to Members of the California Legislature and Governor Gavin Newsom, urging the passage of Senate Bill 328 (SB 328), a bill that would set healthier limits on how early in the day state middle and high schools can start classes.
 
Because of changes in the sleep cycle that occur during puberty, health experts recommend that middle and high schools start no earlier than 8:30 a.m. The bill, introduced by Senator Anthony Portantino, is co-sponsored by the nonprofit Start School Later and the California State PTA and has widespread support from a host of health, safety, and education groups including the American Academy of Pediatrics California, the California Medical Association, the California Police Chiefs Association, the American Academy of Sleep Medicine, the California Psychiatric Association, the National Sleep Foundation, and myriad hospitals and universities. 

Schools in at least 22 states to delay bell times this year.

[Updated 8/17/19] -- School districts in at least 22 states plan to delay morning bells this year according to the national non-profit Start School Later (SSL). Topping the list are 5 districts in Ohio, 5 in Pennsylvania, and 4 in Massachusetts and Colorado.
 
“Every year, we see more districts moving bell times back to more reasonable hours in response to the research," observes SSL's Executive Director Terra Ziporyn Snider, PhD. “Health professionals have been telling us for years that teenagers cannot get healthy sleep when they have to wake at 5 or 6 a.m. for class. It’s gratifying to see so many communities prioritizing student health and safety by turning these recommendations into school policy.”

Governor vetoes school start time bill supported by leading medical groups.
 
California Governor Jerry Brown vetoed Senate Bill 328, legislation that would have restricted middle and high schools from starting before 8:30 a.m. – a recommendation that has been made by the American Academy of Pediatrics, the Centers for Disease Control, and the American Medical Association. The bill, introduced by Senator Anthony Portantino, was sponsored by the nonprofit Start School Later and supported by a host of health, safety, and education groups including the California State PTA, the California Police Chiefs Association, the California Federation of Teachers, and myriad state hospitals and universities. 

​​Schools in at least 20 states to delay bell times this year
 
School districts in at least 20 states will be ringing the first bell later this year according to the national non-profit organization Start School Later. These districts include nine in Pennsylvania and seven in Massachusetts. ​

​Southern Maine    April 11, 2016 
In an historic collaboration, separate school boards in Southern Maine voted simultaneously to adopt later school day start times. Next school year, Biddeford, Dayton, and Saco, along with Thornton Academy, will be the first districts in the state to require compliance with CDC recommendations that middle and high school start no earlier than 8:30 a.m.
