Louisiana Contractor License Exam Prep

Louisiana contractors are licensed by the Louisiana State Licensing Board for Contractors. Most classifications sit a trade paper plus Law & Business. Need only the business paper? It is sold standalone. If you buy a Louisiana classification that sits that exam, that paper is 75% off where we offer it.

Confirm question count, time, open-book rules, and passing score on the live board bulletin before you sit. We do not publish a single Q-count for every classification on this page, and we do not guarantee a passing result.

How to get licensed in Louisiana

Louisiana licenses through the State Licensing Board for Contractors (LSLBC). The first thing to establish is not your trade but the value of the job — Louisiana sets a different dollar trigger for each kind of work, and they are far apart.

  1. Find your dollar threshold before anything else. A commercial licence is required for commercial construction projects of $50,000 or more; one dollar or more for hazardous materials; and in excess of $10,000 for plumbing, electrical or mechanical work. A residential licence is required when the cost of the undertaking is $50,000 or more. Project value includes labour, materials, rentals, and direct and indirect expenses.
  2. Smaller residential work needs registration, not a licence. Home improvement contractors must register with the Board when total project value is $7,500 or more but less than $50,000. Contractors already holding a valid building construction or residential construction licence with the Board are exempt from that registration.
  3. The net worth requirement is $10,000 — and it can be bridged. The applicant’s assets must include a net worth of at least ten thousand dollars. An applicant without it may instead furnish the Board a bond, letter of credit or other acceptable security in the amount of the requirement plus any negative net worth; doing so is deemed to satisfy the net worth requirement for all purposes.
  4. File a financial statement current to within twelve months — once. Commercial, residential and mould remediation applicants must furnish the Board a financial statement current to within twelve months. No financial statement is required for a licence renewal.
  5. Carry the required insurance. Residential contractors must submit certificates evidencing workers’ compensation coverage under Title 23 of the Louisiana Revised Statutes and general liability insurance of at least $50,000 at both application and renewal. Mould remediation applicants and licensees must show $50,000 general liability plus workers’ compensation.
  6. Designate a qualifying party. An applicant for commercial, residential or mould remediation licensure must designate a qualifying party — a natural person who is the contractor’s legal representative for the purpose of complying with the chapter, including meeting the examination requirement.

Sources: Louisiana State Licensing Board for Contractors, its licensing checklist, and the Board’s Contractors Licensing Law and Rules and Regulations (revised 1 August 2024), from which the thresholds, net worth, financial statement and qualifying party requirements above are taken. Contractor Pathway is an independent exam-preparation provider and is not affiliated with the LSLBC.

Choose your Louisiana classification

Each course includes a comprehensive study guide — often 10,000 words or more — worked calculations, code-section breakdowns, common exam traps, a glossary, and a 30/60/90-day study plan — plus four full-length practice exams matched to the topic weightings of the Louisiana test.

Louisiana contractor licensing — FAQ

Who licenses contractors in Louisiana?

The Louisiana State Licensing Board for Contractors (LSLBC). As of August 2025, all LSLBC trade and business/law examinations are administered by PSI, with scheduling and payment handled directly through PSI.

What exams does Louisiana require?

A Business and Law exam (50 questions, about 2.5 hours, open book) covering licensing statutes, lien law, tax withholding, contract clauses, and OSHA – plus a trade exam for your classification. The passing score is around 70%.

Can the NASCLA exam be used in Louisiana?

Yes – for commercial building, the NASCLA Accredited Examination for Commercial General Building Contractors may substitute for the state trade exam. You must still pass Louisiana’s Business and Law exam separately, and a NASCLA pass can simplify licensing in other states that accept it.

Are the Louisiana exams open book?

The Business and Law exam is open book, so fast, well-indexed reference navigation is the decisive skill. Confirm the current content outlines and reference lists on PSI’s Louisiana contractor page before you test.

How long should I study for the Louisiana exam?

Most candidates do well on a 30-, 60-, or 90-day plan depending on experience, which is why we offer access at all three terms ($99 / $129 / $169). Each guide includes a day-by-day study plan.
