Most of the elementary schools in our county start at 8, with middle school at 8:15 and high school at 7:45.
But, my kids are up & out the door at 6:30 due to DH's & my work schedules. DD2 goes to daycare for before & after school care and DS & DD1 stay at their grandmother's along with our niece since they're in middle school.
As for sleep, bedtime routines start at 7 for the youngest, and the other two come upstairs at 7:30 for Bible time and then they do their half hour of reading and baths, etc, so they're in bed by 9:30 at the latest. Which works since I'm in bed between 9 & 10.
For early dismissals, the daycare has extra staff on those days for the school kids and the other two either go to Grandma's or I pick them up if she's unable to.
