And research supposedly shows that teenagers need to sleep later in the morning, so would imply later start and finish.

Hot tip: it won’t.

Has anyone asked the teachers or the kids?

Please stop broadcasting the mistruth that schools operate from 9-3. I’ve taught for 30 years. I arrive on campus at 7:15, lessons start at 8:20, classes finish at 3:20, meetings and co-curric activities go til late. Then I take work home! 9-3????? #breakfast
