Best practices for securing classroom doors at your K-12 school

To help prevent school shootings, your K-12 school may examine the security of its classrooms and doors. Follow the considerations and practices below to help your school best secure its doors in a potential active shooter situation.

Offer an Interior Locking Option

Doors that lock from inside are most effective in securing a classroom, according to a 2015 report by the Sandy Hook Advisory Commission. Exterior locking doors may put teachers or others in the path of an active shooter by requiring them to go into the hallway to lock the door. In the February 2018 shootings at Marjory Stoneman Douglas High School, teachers were injured or killed while trying to lock their classroom doors from the outside.

Even if doors have interior locks, they should be accessible from the outside to administrators and emergency personnel. Provide these individuals with keys or an exterior access method.

Consult Experts About Barricades

Barricades can effectively secure classroom doors, but most don’t comply with state and local fire codes. From rubber doorstops to an industrial grade security device designed specifically for a school door, the complexity and cost of barricades are wide-ranging. Consult with an attorney and security expert before buying these devices.

Secure Doors That Have Windows

For doors with windows, provide a covering to obstruct a shooter’s view into a classroom. Temporary coverings are preferable because permanent classroom privacy may increase the risk of sexual molestation, which occurs more often than shootings.

Review the placement of windows on or near doors because active shooters might fire through glass to gain entry. Consider making glass doors and windows shatter- and bullet-resistant. If possible, install classroom doors made of bulletproof materials.

Comply With Codes and Requirements

Identify and comply with applicable building and fire codes, life safety codes, laws, regulations, and other requirements. Use the National Association of State Fire Marshals’ (NASFM) checklist of best practices for classroom door security. It’s based on building codes, life safety codes, fire codes, and federal laws.

Engage Internal and External Security Experts

When securing doors, seek guidance from staff members with security and liability expertise.

Also consider contacting an outside security expert to review your approach to securing doors and your school’s overall physical security. A fresh perspective can identify gaps.

Document Your Process

Once your school decides how it will secure doors, consult with counsel about the best way to document your school’s thought process. That documentation can be important in showing your school acted reasonably if a related claim arises.
