Sleep deprivation in teenagers is linked to mental health struggles, worse grades, traffic accidents, and more. That's why states including California and Florida have mandated later start times. Individual districts across the country have made the same change.

The Uvalde school district has picked its new superintendent after a year without a permanent leader, as a large Florida district and a half dozen others also filled vacancies at the top.

"There were no traditions or routines yet," Principal Ahna Davis says of Cabot Freshman Academy. "We got to create the school that we wanted. Ten years later, it is still a fantastic school!"

Superintendent Peter Hannigan's series of video interviews with students and other activities was "renewed" for a second season after a five-episode run last school year. "Being visible as a superintendent is one of my top priorities," says the Chicago-area district leader.
