Seattle Public Schools will introduce new "bell times" across their entire system when the new school year starts on Sept. 7. The district has sent letters to parents announcing the changes which can be as much as 45 minutes later than they were in earlier years.
Bell time revisions for local schools can be found below and the complete list here: http://bit.ly/1XYIVGV
From the letter sent to parents by Pegi McEvoy, Assistant Superintendent Operations:
"Research has shown that teenagers benefit from later start times resulting in more sleep, better health, reduced discipline and improved truancy rates. During the district’s community engagement process, most feedback from the community supported earlier start times for our younger students. Additionally, research has shown no negative impacts on elementary students when school begins earlier.
