(WHAS11) -- The Newtown tragedy has led many schools across the country to rethink their security.
Manual High School in Louisville started making a big change that will help them quickly identify students.
A school wide effort is underway to make sure every student has an ID that can be worn and is visible.
"One thing we can do better is quickly identify our students in the hall. We have 1900 amazing students," Principal Larry Wooldridge said.

"There are also students that walk to UofL everyday through or by our campus. We have 1200 students that walk from Manual building to YPAS building so we need to know who our students are at the drop of a hat," Wooldridge said.
Officials are hole punching ID's and issuing lanyards so they can be worn around their necks or on their belts. An extra measure to make the students and their parents feel a little safer.
"They can put it on their belt. It just needs to be visible so if we see a group of students walking down the hall, we can quickly identify that they are supposed to be in the building or if this person is not supposed to be in the building ," Wooldridge said.
