Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

Generally it's the same. However, you would think the ISD police would train at the different campuses to get a feel for each school. Uvlade isn't that big, I'm sure the local PD could take time to train there too. In light of all the school shootings that occur in this country, you would think this would be common place.
The only different strategies that I taught was active shooter vs barricaded suspect.
The active shooter drill is the same everywhere. I'm a civilian employed at Keesler AFB. We have the drill at least
once per year. Our instructor is a retired Chief Petty officer. He said Military and Civilian training are the
same. Run first hide 2nd and fight as a last resort.
