Two states — California and Florida — have passed laws that require high schools to start no earlier than 8:30 a.m. But simply telling a teenager to get to bed earlier doesn’t always work, as any parent can attest: They need to be convinced.

That’s why Mansfield City Schools, a district of 3,000 students in north-central Ohio, is staging what it calls “a sleep intervention.”The district’s high school is piloting the new curriculum, “Sleep to Be a Better You,” hoping to improve academic success and reduce chronic absences, when a student misses more than 10% of the school year. The rate of students missing that much class has decreased from 44% in 2021 but is still high at 32%, says Kari Cawrse, the district’s attendance coordinator. Surveys of parents and students highlighted widespread problems with sleep, and an intractable cycle of kids going to bed late, oversleeping, missing the school bus and staying home.

The students in Davis’ classroom shared insights into why it’s hard to get a good night’s sleep. An in-class survey of the 90 students across Davis’ five classes found over 60% use their phone as an alarm clock. Over 50% go to sleep while looking at their phones. Experts have urged parents for years to get phones out of the bedroom at night, but national surveys show most teens keep their mobile phones within reach — andDuring the six-part course, students are asked to keep daily sleep logs for six weeks and rate their mood and energy levels.
