Back in my day we had "duck and cover" drills for earthquakes and/or nuclear warfare. The teachers were informed, but the students were not but were trained what to do.
These days in Los Angeles, drills for all kinds of things are a common place occurrence and lockdowns are frequent. Sad to say there are frequent gun fights right across from schools.
Also the incidences of students (grammar school level) bringing unsecured fire arms from home are increasing. I think that level might be a good scenario for a second gen story also.
