high school #1 i attended - we were allowed to leave campus no matter what the grade, we were however only allowed to stay within the great hall areas and not allowed in the hallways what so ever as classes were still going on
grade 9&11 would have the same lunch break and grade 10&12 would share have the same this was to ensure there was a good enough age range in the cafe at all times and it did work fairly well, if you had a spare or study period you were only allowed in the cafe, or in the library and no sitting in the hall
- start time - 9:15 ended at 3:15 i believe (best time to start and end) lunch was about an 1 hour 15 minutes - 1 hour 30 minutes with 4 classes
High school #2 i attended closed campus nobody allowed on or off whatsoever and everybody had the same lunch period (it was dreadful) lunch was 40 minutes with 6 classes
- start time - 8:12-3ish monday, tuesday and friday wednesday we started at 9
and finally high school #3 we had 3 lunch periods (so depending on what classes you had you may or may not have had lunch with friends) we were allowed to leave for lunch but were not allowed to roam the halls and were confined to the cafe, great hall, library, or any open classroom with a teacher present.
- start time - 8:30-2:30 - lunch was about an hour with 4 classes
