It's hard to believe summer's almost over. But the first day of class for students on Seattle Public Schools campuses is less than three weeks away, on Sept. 7.

With the new school year upon them, school officials are scrambling to remind parents of new school start and end times in the 2016-2017 school year. The district sent out reminder letters in six different languages at the beginning of August. 

In November 2015, the Seattle School Board voted to start the school days of its high schools, most of its middle schools and a handful of K-8 schools at 8:45 a.m., in response to research on the health benefits of giving adolescents more time to sleep. Many elementary schools will begin earlier under the new schedule.

"Research has shown that teenagers benefit from later start times resulting in more sleep, better health, reduced discipline and improved truancy rates," Assistant Superintendent Pegi McEvoy wrote parents.

In North Seattle, three-dozen campuses will be affected by the bell time changes.

Along with all other Seattle high schools, Ballard, Ingraham, Nathan Hale and Roosevelt will all begin the school day at 8:45 a.m. and end it at 3:15 p.m. All North Seattle middle schools, including, Eckstein, Hamilton International, Jane Addams and Whitman, will adopt the same schedule.

Madrona K-8 will begin the school day at 7:55 a.m and end it at 2:25 p.m. Leschi and McGilvra elementary schools will begin the day at 7:55 a.m. and end it at 2:05 p.m.

All K-8 schools on the north end, with the exception of Broadview-Thomson, will also adopt the high schools schedule. Broadview-Thomson will begin the school day at 7:55 a.m. and end it at 2:25 p.m.

Most elementary schools are adopting a 7:55 a.m. to 2:05 p.m. schedule. However, some will operate differently.

Loyal Heights Elementary School will begin the day at 8:45 a.m. and end it at 2:55 p.m.

Meanwhile, Adams, Laurelhurst, North Beach and View Ridge will all operate on a 9:35 a.m. to 3:45 p.m. school day.

A full list of new school bell times can be found at a dedicated web page on the Seattle Public Schools website. The district has also compiled information on after-school and care programs here.
