SOUTH BEND, Ind. (AP) — Indiana leaves it up to each public university to come up with plans on how to prepare for dealing with a gunman on campus.

A review by The Associated Press of practices in more than three dozen states eight years after the Virginia Tech massacre prompted tighter campus security measures found that practices range from mandatory active shooter training to little guidance.

Schools in Indiana generally give students and staff advice on what to do in those situations.

All of Indiana’s public universities have emergency alert systems that send text and email messages to students and staff.

All the four-year universities except the University of Southern Indiana have armed police officers, while USI has unarmed public safety officers. Ivy Tech Community College, with 32 campuses, has unarmed security officers.
