How to Become a Police Officer in Missouri

Missouri is the “Show Me State” and residents here are proud of their midwestern heritage. With rural farmland, thriving suburbs and the cultural metropolises of Kansas City and St. Louis, Missouri has something for everyone. That includes anyone interested in a career in law enforcement. There are 12,810 cops and sheriff’s deputies employed here with plenty of opportunities for new recruits.1

The Missouri Department of Safety’s Peace Officer Standards and Training, or POST, is responsible for setting the minimum requirements for working in law enforcement in the state. It also sets the examination that all hopeful cops and deputies must pass.

Missouri Sheriff Deputy Requirements

Each Missouri county sets its own hiring process for sheriff’s deputies. The minimum requirements for working as a deputy are those set by POST, but each sheriff’s office can include further requirements, testing, and hiring procedures.

Jackson County

Jackson County is home to the state’s largest city, Kansas City, and the Jackson County Sheriff’s Office offers opportunities for young recruits hoping to work in law enforcement. Patrol deputies have the chance to work with the K-9 Unit, the Motorcycle Unit, the ATV Unit, or the Emergency Response Tactical Team. When hiring, the office gives priority to individuals who are already POST-certified for working in a Class A county.

Cole County

The capital of Missouri, Jefferson City, is also the county seat of Cole County, where the sheriff’s office sets strict standards for recruiting deputies. In addition to POST licensing, new recruits must:

  • Have completed 60 college credit hours, served three years in the military, or worked three years as a POST-licensed peace officer
  • Not have visible tattoos
  • Have a clean driving record
  • Have no felony convictions or arrests
  • Pass an extensive background check, including a polygraph test

Police Departments in Missouri

For those hopeful future cops, Missouri offers a variety of local police departments. From small, rural departments to the big cities, Missouri has plenty of opportunities for new cops. To become an officer in any of the state’s local departments, a new recruit must meet the POST standards and pass the exam to become licensed. Once this has been achieved an individual must then meet the requirements of the local department, be offered employment, and complete a course at a training academy.

Kansas City

Kansas City is Missouri’s largest city and it sits on the border with Kansas, right next to that state’s Kansas City. The population is around 460,000 and the city is most famous for its legendary barbecue. Recruits to the Kansas City Police Department must first meet the POST standards and pass the exam and a physical abilities test. The recruits must then:

  • Undergo a background check
  • Pass a polygraph test
  • Go on an officer ride-along
  • Pass an oral interview
  • Pass a physical and psychological examination

Once a candidate has successfully completed each stage of the hiring process, he or she is placed in a pool of eligible candidates. Only when the recruit has been offered employment from this pool will he or she then attend and complete a training academy program.
