California law requires high schools outside of rural areas to start classes no earlier than 8:30 AM. No such law exists in Oregon, but human biology does not recognize state lines; teens can still be very sleepy early in the morning.
So Grants Pass High School has already decided to embrace the 8:30 start time for the next school year, giving students another 40 minutes to get awake and get to class. The major instigator is a student, Anika LaFrance-Hernandez, who researched the same studies California used to justify later start times.
We get the story of the process of changing from Anika and GPHS Principal Ryan Thompson.
