ExploreAbout this exam
The Missouri Peace Officer License is the state credential a person must hold to work as a peace officer in Missouri. The program that issues it, Peace Officer Standards and Training (POST), sits inside the Missouri Department of Public Safety and operates under Chapter 590, RSMo. POST describes its own duties as licensing peace officers, enforcing continuing law enforcement education (CLEE) requirements, and investigating officers so that licenses can be disciplined. The same office also licenses basic training centers and basic training instructors and approves law enforcement training curricula, and it staffs the POST Commission.
Eligibility requirements are listed plainly by POST: the applicant must be 21 years of age, be a U.S. citizen, hold a valid high school diploma or its equivalent, be a graduate of a Basic Law Enforcement Training Center, have passed the Missouri Peace Officer License Exam, and have no criminal history as outlined in sections 590.080.1 and 590.100.1, RSMo. Out-of-state, federal and military applicants, and officers whose license has expired, apply through the Veteran Peace Officer Application in the POST Forms section.
The licensing exam samples the academy curriculum: criminal law and procedure, patrol and community relations, investigations and evidence, traffic and crash work, use of force and firearms, emergency driving, report writing, ethics, and first aid and wellness. Build your study plan from your training center's objectives, Chapter 590 and the POST administrative rules, then layer on the current CLEE material.
What you'll study
About MO POST preparation
Who actually needs a Missouri peace officer license?
Anyone who will exercise peace officer authority in Missouri. POST frames the license as the regulatory gate: it licenses peace officers, tracks their continuing education, and investigates them for discipline. Basic training centers, basic training instructors and continuing education providers are licensed separately through the same program, so a training credential is not an officer license.
What are the eligibility requirements to be licensed?
POST lists six: be 21 years of age, be a United States citizen, hold a valid high school diploma or its equivalent, be a graduate of a Basic Law Enforcement Training Center, have passed the Missouri Peace Officer License Exam, and have no criminal history as outlined in sections 590.080.1 and 590.100.1, RSMo. All six apply together, not as alternatives.
What does the Missouri Peace Officer License Exam cover?
Expect the exam to follow the basic training curriculum: criminal law and procedure, patrol operations and community relations, investigations and evidence, traffic enforcement and crash investigation, use of force and defensive tactics, firearms, emergency vehicle operations, report writing, ethics, and first aid and officer wellness. Use your training center's learning objectives as the outline of what is testable.
How many questions are on the exam, how long is it, and what score do I need to pass?
We cannot state those figures, because the POST pages we reviewed do not publish a question count, time limit, or passing score for the Missouri Peace Officer License Exam. Treat any specific number you see elsewhere as unverified. Confirm the current test blueprint and cut score directly with POST or your basic training center before you plan your timing.
What does the license cost, and where do I register for the exam?
No fee, registration portal, or scheduling process appears on the POST licensing or program pages we reviewed, so we do not publish a number. Candidates normally get exam scheduling instructions through their licensed Basic Law Enforcement Training Center. For authoritative answers, contact the POST Program in Jefferson City at (573) 751-3409 or [email protected].
I was licensed in another state, or I served in the military. Do I start over at an academy?
Not necessarily. POST directs out-of-state applicants, federal and military applicants, and officers whose Missouri license has expired to apply through the Veteran Peace Officer Application, which is posted in the POST Forms section. Work through that form first; POST decides what training or testing you still need rather than assuming a full academy repeat.
What happens after I am licensed - is there continuing education?
Yes. POST is responsible for ensuring compliance with continuing law enforcement education (CLEE) requirements, and the program publishes annual CLEE training and reporting requirements plus a POST CLEE Tracking System for officers. Failing to complete and report CLEE exposure is a licensing risk, so track your hours in the state system rather than relying on local records.
Which parts of the exam should I study first, and where do candidates lose points?
Start with the legal block, because criminal law and procedure questions reward precise element-by-element recall and punish vague familiarity. Then drill report writing and traffic crash investigation, which reward structured, sequential thinking. Leave firearms and defensive tactics terminology for last but do not skip them; they are vocabulary-heavy and easy to secure with short review sessions.
What if my license lapses or POST files a complaint against me?
POST runs a defined disciplinary process and publishes a complaint form, a quarterly update of revoked and surrendered licenses, and investigator contacts. A lapsed license is handled through the Veteran Peace Officer Application rather than a fresh application. If a complaint is filed, respond through the POST disciplinary process and keep your own documentation.
