Louisiana Contractor License Exam Guide (2026)

How Louisiana licenses contractors

The LSLBC licenses Commercial, Residential, and Specialty contractors statewide. PSI (test-takers.psiexams.com/laslbc) administers the Business & Law and trade exams, including the NASCLA exam accepted for Commercial Building.

Louisiana’s bayous bring hydrostatic pressure, uplift, and black mold. Exams drill FEMA P-55 floodproofing, ASCE 7 wind maps, corrosion mitigation, and storm-hardened electrical/standby systems for 105°F heat index days.

A focused 4-week study plan for the Louisiana exam

Because Louisiana’s bayous bring hydrostatic pressure, uplift, and black mold, this four-week outline targets what Louisiana 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: FEMA coastal construction manual and ICC 500 shelter requirements.
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: ASCE 7 wind pressures for Exposure D along the Gulf.
3. Week 3 — Business & Law. Louisiana’s Business & Law module is 50 questions/2.5 hours and covers licensing statutes, lien law, tax withholding, contract clauses, and OSHA requirements. It’s open book but reference navigation must be fast. Layer in scenario-based questions on contracts, lien notice, payroll, and insurance.
4. Week 4 — Full simulations. PSI offers exams in Baton Rouge, Bossier City, Harahan, Lake Charles, Shreveport, and remote proctoring slots. Run two full-length timed simulations. Review every miss with a one-sentence rule statement.
