Atascocita Middle School has a staggered bell schedule and it seems to be working well. One grade at a time changes classes. It avoids overcrowding in the halls, as well as prevents the bigger kids from picking on the younger kids. I wonder why AHS doesn't implement this. From the looks of that picture, that's got to be a fire code viloation to have that many people in the halls at one time.

Correction: 7th & 8th share a bell schedule. 6th has their own bell schedule.
