We had four high schools in our city that used the school buses.
One started at 7, two started around 7:30ish, the fourth started around 8:30.
I was in the 8:30 school. We didn't like it because we didn't get out until 3:30, so all of the other high schools had been out for over an hour at that point. It was a point of rivalry contention between schools.
I've only seen it the other way around, though. Elementary starts first around 7:30 am, middle school at 8 and high school 8:30.
Good God! 7.30!
9am start here for more or less everything, give or take 10 minutes (Ireland).
My preschooler is 9.30.
