School Reunion and Intruder Prevention Newsletter: How Families Help Keep Buildings Secure

Most school security incidents do not begin with a forced entry. They begin with a propped door, a tailgater who slipped through behind a parent who held the door, or an unauthorized individual who walked in during a busy arrival period and was never challenged. Families who understand these realities can be the school's most effective security partners.

The Tailgating Problem

Tailgating happens when an unauthorized person uses an authorized visitor's momentum through a secured door to enter without checking in. Most people who hold a door open for the person behind them are being polite. They do not know that the polite thing to do in a secured school entry is to let the door close and let the next person check in independently.

The newsletter should name this directly: if you are entering the school and someone is behind you, let the door close. This is not unfriendly. It is part of how the school keeps every child inside safe.

The Propped Door Problem

Propped doors appear at every school, usually because someone needed both hands, expected to return in a moment, or simply wanted to let in fresh air. Every propped exterior door is an open entry point for anyone who passes by. The same security investment that went into the visitor management system at the front desk is bypassed entirely by a rock holding a side exit open.

Families who see a propped door should close it and notify a staff member. Students who prop doors should know it is a policy violation. This is a simple behavioral change with real security impact.

What to Do When You See Someone Who Does Not Belong

Give families and community members a specific protocol. If you are in the building and see an adult you do not recognize who does not appear to have a visitor badge, tell the nearest staff member or contact the main office. Do not approach the individual yourself. Give a description and location.

If you are outside the building and see someone attempting to enter through a non-main-office door, or sees someone who just entered a non-main-office door without a badge, contact the main office by phone immediately. The school can investigate without creating a confrontation.

During High-Traffic Moments

School arrival, dismissal, and events such as science fairs and parent nights are the highest-risk moments for unauthorized entry because legitimate traffic is heaviest. The newsletter should acknowledge this and ask families to be more attentive during these windows, not less.

A parent arriving at the school concert who notices a door propped near the gymnasium is in a perfect position to close it and alert staff before the event begins.

Community Culture and Security

Building security depends on community culture as much as on cameras and door locks. A community where families understand why these behaviors matter and practice them consistently is significantly more secure than one with the best equipment and no shared understanding of why it matters.
