Hennessey Public Schools had a big change during the summer. The schools now have bulletproof windows and doors to better protect students. Not only that, but the doors are locked at all times and only unlock during passing periods or when the door is unlocked by an app. To let someone know that you are outside, simply press the button by the door and it will send a notification threw an app. Once you are recognized, the door will unlock and lock behind you. You are also able to talk to the person administering the app. This ensures that no one walks in the schools unnoticed.
