You know, it's pretty rare that politicians actually listen to the science, but California pulled it off with school start times. According to CalMatters Housing, back in 2018, Governor Jerry Brown vetoed a bill that would have pushed back when middle and high schools started their day, citing local control concerns. But when Gavin Newsom took office and faced the same proposal a year later, he signed it into law, creating a requirement that most middle schools start no earlier than eight in the morning and high schools at eight thirty.
The pushback from opponents had been significant over the years. According to the reporting, school officials and parents worried about the domino effects on everything from sports to work schedules, particularly for families already dealing with tough circumstances. But the research community had been pretty clear that students weren't getting enough sleep when schools started too early, and that was affecting their health and their ability to learn.
Well, it turns out the science won. According to CalMatters, a study published recently by the National Bureau of Economic Research looked at what happened between 2022, when the law took effect, and 2025. The researchers found that students are sleeping more, reporting fewer mental health problems, and performing better on math and English tests. What's especially interesting is that these improvements showed up across all student groups, but were particularly noticeable for boys and Latino students.
What I'm seeing locally here in the Bay Area is that while the transition had its challenges, we're in a region that tends to embrace these kinds of evidence-based changes. For families thinking about where to send their kids to school or considering moves between districts, this is one more factor pointing toward real, measurable benefits that extend beyond just the logistics of getting kids to campus. It's a reminder that sometimes the harder choice upfront pays off for everyone.
