School districts across the country constantly evaluate their safety procedures and resources to make sure their campuses are safe for every student who walks through their doors.
Tuesday's incident at a Georgia elementary school, where an armed man snuck into a controlled access door, served as another reminder that schools must constantly stay on alert.
The situation ended without any children harmed and the suspect arrested.
"I think any time as a parent you hear about a school shooting, you're going to be concerned, but (parents) should also be very confident in the precautions and preparation we take in the Northeast school district," said Northeast Independent School District spokesperson Aubrey Mika Chancellor.
The district, like others across the area, has surveillance cameras on all campuses and controlled access along with the RAPTOR ID system, which checks the drivers license of every visitor.
In addition to many of their safety systems, NEISD is one of the few districts to employ a risk management department.
"Year-round, they're conducting safety audits, they're looking at potential problems and what may need to be corrected," said Chancellor.
Smaller districts, like Southside ISD, which has schools in rural settings, share the same concerns and often the same security systems.
"The dynamics can be a little different, but as far as security, we have to follow procedures," said Jorge Topete, Southside ISD spokesperson. "We meet with other districts and we actually bounce off ideas from each other, experiences that they've had. We work with all of the resources we have available."
Most districts have dedicated district police officers at all middle schools and high schools with other officers on constant patrol near every elementary school.
Northside ISD spokesperson Pascual Gonzalez said this year, the district began a community policing force with seven police officers split among the 73 elementary schools.
The officers are given a certain number of campuses to become familiar with staff and parents to better prepare themselves in case of an emergency.
