The district has put out the bus arrival/departure times for next year. It doesn't say preliminary or draft at the top but I don't think this has been signed off on yet. I believe the final decision will come in early May.
Note: the bell times will be somewhat variable as the listed times are for BUSES, not bell times. The schedule says that "morning start times are generally 15 minutes after bus arrival. Afternoon end times are generally 5-10 minutes prior to the bus departure.)
I don't see a lot of change at the high school level (although it seems that Cleveland has a slightly longer day than other schools starting at the same time.) I note that West Seattle used to start at 8:10 am and it appears they will start around 7:50 am.
All of the K-8s start around 9:10 am with middle schools starting around 7:50 am (except for Jane Addams at 8:20 am and Denny with a TBD designation). The outliers are Pinehurst which ends 10 minutes earlier than the other K-8s and Aki Kurose which gets out nearly an hour later than the other middle schools (but starts at the same time).
It looks like elementaries start either around 8:30 am or 9:00 am. There are a few outliers (Hawthorne and West Seattle but they already operate on a longer day/longer year schedule).
I'm a little confused because I thought they going to go towards later start times for high school and middle school. Maybe that's next year?
