All it takes is one side door left unlocked or opened by a kid on the inside.

I suppose they could alarm the doors and that "hardened" school had a
bunch of surveillance, monitored from the office, with a link to the
cops. If the door alarm goes off in the office, they could look at the
monitor and know right away if this was a shooter or just a kid
sneaking out for a smoke.
You could harden a school pretty cheaply (in school board bucks) by
installing a bunch more cameras, a decent alarm/communication system
that indicated where the shooter was (display in each classroom) and
toughen up the classroom doors. If the shooter is trapped in the hall
with no one to shoot and being watched all the time. it would not be
that hard for the cops to hunt him down and kill him.
