Colorado district may push back high school start times
The district says parents, students and staff members who responded to a survey last year overwhelmingly supported moving the start time to 8:15 a.m. for high school and 8:50 a.m. for middle school.
National studies show high school schedules typically force teenagers to forgo sleep and to wake up during deep sleep, while research indicates elementary school students have more willingness to learn at an earlier time.
