So it looks like your schedule is changing if you have highschool age kids. High schools will start an hour later next year, beginning the day at 8:30 a.m. and ending at 3:25 p.m.
The school board conducted a vote...it was 6-0 in favor of a new schedule.
Elementary schools will run from 7:40 a.m. to 1:55 p.m., and middle schools from 9:25 a.m. to 4:20 p.m. There are some exceptions. Check this link.
