Missouri Contractor License Exam Guide (2026)

How Missouri licenses contractors

Missouri has no statewide GC license; jurisdictions such as St. Louis City/County, Kansas City, Independence, Springfield, and Columbia issue Class A/B/C licenses. Most require ICC National Standard exams or equivalent credentials.

Central U.S. contractors face EF4 tornado threats, 90°F humidity, Ozark karst sinkholes, and riverine floods. Local exams emphasize storm shelters, floodproof foundations, and structural steel bracing in Seismic Design Category C.

Missouri contractor license types

St. Louis and Kansas City require $500,000 liability insurance, $500,000 property damage, and $20,000 surety bond. CE requirements vary: Kansas City requires 8 hours annually.

A focused 4-week study plan for the Missouri exam

Because central U, this four-week outline targets what Missouri field inspectors and your licensing board exam items actually test—not generic national prep.

1. Week 1 — Map the exam. Pull your current candidate bulletin, list every reference, and confirm the modules you have to pass. Start a one-page error log. Spend extra time on: ICC code content: IBC/IRC structural, egress, and mechanical provisions.
2. Week 2 — Code book navigation. Drill open-book lookups (or memorisation drills if your module is closed-book) until you can find any answer in under 60 seconds. Anchor practice around: Tornado safe room (ICC 500) anchorage details.
3. Week 3 — Business & Law. Cities embed business-law content into their licensing requirements—expect questions on contracts, insurance, bonds, taxes, and safety when taking ICC or local law exams. Layer in scenario-based questions on contracts, lien notice, payroll, and insurance.
4. Week 4 — Full simulations. Pearson VUE offers ICC exams in Kansas City, St. Louis, Springfield, Columbia, and nationwide. Run two full-length timed simulations. Review every miss with a one-sentence rule statement.
