360° State Trooper:

A mission to systematically train and mentor professional and highly effective Illinois State Troopers. The initiative, following the “Lifecycle of the 360° State Trooper” model, focuses on Troopers as they are hired and continues throughout the first five years with strategically placed training and mentorship opportunities to ensure these Troopers are trained at a consistent level. Ultimately, this concept will build safer, more confident, more proficient State Troopers that are better able to communicate with the public, recognize suspicious activities, and maximize public safety. These meticulously trained Troopers will enhance the missions of the Division of Patrol as well as branch out to other Divisions within the Department to serve them well.


The mission of the Division of Patrol is to promote public safety by enforcing the law, focused on traffic safety and the interdiction of crime.
