Exam Requirements

Provider: PSI

Cost: $60–$100

Topics covered: Missouri Code, Trade knowledge

Most state contractor exams test two main areas: Business & Law (contracts, lien law, workers' comp, licensing regulations) and Trade Knowledge (construction practices, building codes, safety). Prepare for both sections — even experienced contractors struggle with the Business & Law portion without dedicated study.

Study Resources

  • PSI Candidate Handbook (available on PSI website — free, covers exactly what's on the exam)
  • ICC Study Guides for code-based exams
  • Contractor's Business & Law Study Guide by Craftsman Book Company
  • Online prep courses from Contractor Exam Prep and similar providers

Insurance & Bonding Requirements

Required locally

Beyond what Missouri requires, consider these coverage types for complete protection:

  • General Liability: Protects against third-party bodily injury and property damage claims
  • Workers' Compensation: Required if you have employees; protects against job-site injury claims
  • Commercial Auto: Your personal auto policy won't cover your work truck
  • Inland Marine (Tools & Equipment): Covers tool theft from job site or vehicle

Important Notes for Missouri

Missouri has no state general contractor license. Electrical and plumbing are state-licensed. Cities like St. Louis and Kansas City have their own contractor licensing systems.
