Rochester, MN (KROC-AM News) - The Rochester School District is considering tightening security at the high schools before the start of the next school year.

During his most recent appearance on KROC-AM's Rochester Today Show, Superintendent Michael Munoz was asked if any changes to school security were being considered in light of the tragic school shootings this year in Florida and Texas. His response indicated significant changes were being proposed for John Marshall, Century and Mayo High Schools.

A few years ago, the elementary and middle schools in Rochester were targeted for major security upgrades, with the addition of security cameras and call boxes at the main entrances that allowed the buildings to be locked during the school day. Visitors must "buzz in" and go through a low-level security screening before they're allowed past the school's main office.

Superintendent Munoz says the installation of similar systems at the high schools is being studied. The high schools currently have a staff stationed at the main entrance to greet visitors, but students can exit and enter through a number of points in each building, which is a common occurrence during the lunch hours. The parents of high school and middle school students are being surveyed this summer to gauge whether there is support for instituting the tighter security measures, or if the preference is for less restrictive strategies.
