One school in Central Illinois is still making changes. The Charleston School District has spent hundreds of thousands of dollars beefing up security.
They're putting in cameras and new entrances to the schools. The district is also in the process of adding an app with important information teachers will be able to use in a crisis. They say everything they've done is to help save time in case of an emergency.
"Newtown really brought it to the forefront. This is the first time we've ever seen a mass shooting of elementary children," says Charleston Schools Superintendent Jim Littleford.
The district plans to apply for a safety grant next year to help pay for some of the new changes.
