Philly's public high schools will start later next year in effort to help students in class

The decision to move to a 9 a.m. first bell was based on research that shows teens perform better when they get more sleep

Most public high schools in Philadelphia will switch start times to 9 a.m. starting this fall, in an effort to help students be more alert and ready to learn in class by getting more sleep.

Parents learned about the change in a letter sent out on Thursday, which also said the move will allow for safer travel and less time spent on buses. The adjustment is the latest phase in the district's ongoing strategy to implement a simplified three-tiered schedule across its 217 schools.

In the run-up to the 2021 school year, the district attempted to reduce its 28 start times to three – 7:30 a.m., 8:15 a.m. and 9 a.m. As a result, most of the high schools began at 7:30 a.m. 

All schools with high school grades will be impacted by the change, including those with middle school grades. However, pre-K programs housed in high schools will maintain any current schedules.

All but four of the district's high school's will be shifting to the new start time, said district spokesperson Monica Lewis. That includes Widener Memorial School, Parkway Center City Middle College, the Pennypack House School and the Juvenile Justice Services Center.

All of the district's elementary and middle schools are currently starting at one of the tiered times and will maintain those same schedules next year, Lewis said.

These changes were made in part to help the district cope with the nationwide bus driver shortage and to allow for more frequent sanitization of school vehicles due to the pandemic, the letter says.

The new start times will remain in place through the 2022-2023 school year, but Lewis said it's possible more changes will be made after that.

The district's start times for high schoolers are now aligned with pediatric research that shows teenagers tend to perform better if they can sleep in later. Teens need between eight and 10 hours of sleep per night, but they usually don't get tired until around 11 p.m., Dr. Thanuja Hamilton, a certified sleep medicine specialist in South Jersey, told PhillyVoice.

In order to get to school at 7:30 a.m., many high schoolers in Philadelphia and elsewhere would need to wake up at 6 a.m. or earlier, which would leave them with seven hours of sleep or less.

"Boom, they're automatically sleep-deprived," Hamilton said.

That status quo reduces creativity, alertness and focus, while heightening tardiness, depression and anxiety, she said.

This is why the American Academy of Pediatrics began recommending that middle and high schoolers start no earlier than 8:30 a.m in 2014. The Centers for Disease Control and Prevention followed suit a year later.

Although Lewis said the schedule changes are set in stone for the upcoming school year, the district will hold four virtual community forums later this month. Parents and other stakeholders will be able to provide feedback about the changes and discuss what type of support they might need to make the adjustment.

Participants must RSVP to the events, which will happen at 1 and 7 p.m. on Tuesday, March 22 and again at 11 a.m. and 6 p.m. on Monday, March 28.
