This thesis seeks to answer the question: School start times: Is later better for high school students? Research for this study focuses primarily on high school start times in the United States from 1988 to 2017. Factors include changes at puberty including melanin production, circadian rhythms and homeostatic systems. High school start times of 7:30 a.m. or earlier make it difficult for students to acquire 8.5 to 9 hours of sleep on school nights. Beyond teen biology, there are community factors to consider such as part-time jobs, athletic practices, child care, and school bus schedules. In summary, there is no one clear answer to the question of a later start time being better for high school students.
