John Banzhaf has a short list of simple things a school can do to make themselves a Harder Target.
From the article:

The Banzhaf Security List:

Install classroom doors that can be locked from the inside.
Mark each room with an easy-to-find identification and make up-to-date floor plans easily available for first responders.
Provide all administrators and campus police officers with master keys.
Get police door-opening tools such as the Halligan carried by firefighters.
Install magnetic door-open sensors so administrators can see which doors are open or properly closed in schools.
Make it easy to text via cellphone in an emergency.
Distribute kits to help quickly stop the type of bleeding left by standard AR-15 rounds.
On school apps, make sure it’s easy to find ways to contact police and officials in an active shooting case.
Install one-way peepholes in office and other doors.
Make a limited availability of guns and post signs stating, “Warning, some professors are armed.”
Supply nonlethal weapons, such as bear spray or poles.

When seconds count the cops are minutes away.
Unless you are in Uvalde, in which case they are hours away.
