The primary objective of this study is to assess the effectiveness of later high school start times for improving student educational, health and well-being outcomes. Specific objectives are the following.
- In considering equity, to explore possible differential effects of later school start times among subgroups of students by (where possible to ascertain) age, grade, gender, ethnicity and socioeconomic status.
- In considering equity, to explore possible differential effects of later school start times among subtypes of schools, such as comparing larger versus smaller schools, rural or urban schools, schools with students who walk to school versus those who take the bus or have mixed transportation, public or private schools, or schools in different geographic locations and climatic conditions.
- To identify and explore any adverse or unforeseen effects of later school start times.
- To explore the process of implementing later school start times to identify successful features as well as aspects of context and delivery that might lead to positive or adverse effects.
- To identify and explore the effects of later school start times on the broader school community (including teachers and other school staff, the school neighborhood and the students' families).
This is a protocol.
