Louisiana Carpentry Exam: Complete Study Guide (2026)

You've put in the hours on the job site. Now it's time to make it official. Passing the Louisiana carpentry exam is the key step to getting your carpentry contractor license through the Louisiana State Licensing Board for Contractors (LSLBC) — and with the right preparation, it's very achievable. This guide covers everything you need to know: exam format, topic breakdowns, sample questions, approved study materials, and proven strategies to pass on your first attempt.

Exam Overview

The Louisiana carpentry contractor exam consists of 60 scored questions and gives you 120 minutes (2 hours) to complete them. That works out to two full minutes per question — manageable if you come prepared.

To pass, you need to answer at least 42 of those 60 questions correctly, which equals a 70% passing score.

This is an open-book exam, which is great news. You're allowed to bring approved reference materials into the test room. That said, open-book doesn't mean easy — the questions are specific enough that flipping randomly through a textbook won't cut it. You need to know your references well before you walk in.

Topics Covered on the Louisiana Carpentry Contractor Exam

Here's how the 60 exam questions break down by topic:

Rough Carpentry and Formwork — 27 Questions (Most Important)

This is nearly half the exam, so treat it as your top priority. Expect questions on platform-frame and balloon-frame construction, floor framing components (sill plates, girders, joists, subfloor), wall framing members (studs, plates, headers, cripples, trimmer studs), sheathing and bracing, and all rafter types — common, hip, valley, and jack.

Finish Carpentry — 14 Questions

The second-largest section covers door installation and hardware, window and door trim (casings, reveals, extension jambs), molding installation (crown, base, chair rail), wall treatments, and stair trim including balusters, newel posts, and skirt boards.

Drywall — 7 Questions

Know your gypsum panel types and sizes, fastener spacing, the five finish levels (Level 0 through Level 5), joint taping procedures, and corner bead installation.

Safety — 6 Questions

OSHA requirements are tested here: fall protection trigger heights, personal fall arrest systems, guardrail specs, scaffold safety, and ladder duty ratings and setup angles.

Windows and Doors — 3 Questions

Window types, door core construction, rough opening sizing, hardware installation, and weatherstripping.

Siding — 2 Questions

Siding materials, moisture protection (building paper, housewrap, flashing), and installation methods for wood bevel, wood shingle, and vinyl siding.

Insulation — 1 Question

R-values, insulation types and forms, vapor retarders, and ventilation requirements.

Sample Questions

Here's a taste of what the LSLBC carpentry license test looks like. These questions are representative of the real exam format. Try to work through each one — then check yourself against our practice exam.

Question 1 — Safety
OSHA trench access required within:
- A) 15 ft
- B) 20 ft
- C) 25 ft
- D) 30 ft

This tests your knowledge of OSHA trench excavation rules — a specific code requirement you'll want tabbed in your CFR reference.

Question 2 — Rough Carpentry and Formwork
Anchor bolts used to fasten a sill plate to a concrete foundation wall must extend at least ______ into the concrete.
- A) 5 inches
- B) 6 inches
- C) 7 inches
- D) 9 inches

A classic foundation detail question. The answer is buried in the code — know exactly where to find it.

Question 3 — Finish Carpentry
When a stairway has two handrails, what is the minimum clear width required between them?
- A) 20
- B) 36
- C) 25
- D) 31-1/2

Stair geometry is a frequent finish carpentry topic. These numbers come straight from the IBC.

Question 4 — Rough Carpentry and Formwork
What is the minimum bearing length required for the ends of wood girders on masonry walls?
- A) 3½ inches
- B) 4 inches
- C) 6 inches
- D) 2 inches

Another structural detail that trips up test-takers who haven't flagged this section of their references.

Question 5 — Finish Carpentry
What size finish nails are used to fasten door casing to the wall framing, and what size are used to fasten the thinner edge of the casing to the jamb?
- A) 10d nails into framing; 8d nails into the jamb
- B) 8d or 10d nails into framing; 6d nails into the jamb
- C) 6d or 7d nails into framing; 3d, 4d, or 5d nails into the jamb
- D) 4d nails into framing; 2d or 3d nails into the jamb

This question rewards carpenters who know the finishing details cold — and penalizes guessing.

What Types of Questions to Expect

Here's a breakdown by topic of the skills tested — and how many practice questions we have to help you sharpen them:

• Safety (50 practice questions): OSHA trigger heights for fall protection, personal fall arrest system components, guardrail construction specs, scaffold platform requirements, and ladder setup angles. Expect specific numbers — heights, distances, weight ratings.
• Insulation (6 practice questions): R-value identification by material and thickness, vapor retarder perm ratings, and net free area ventilation calculations for attics and crawl spaces.
• Windows and Doors (20 practice questions): Operating styles, rough opening sizing for windows and doors, hinge and lockset installation, and weatherstripping details.
• Rough Carpentry and Formwork (176 practice questions): This is the engine of the exam. Questions cover framing calculations, member identification, bearing lengths, anchor bolt embedment, rafter types and cuts, sheathing requirements, and bracing methods. Expect a mix of code lookups and applied geometry.
• Finish Carpentry (91 practice questions): Door hand identification, casing nail sizes, molding joinery (coped vs. mitered joints), stair balustrade assembly, and clearance dimensions from the IBC.
• Drywall (46 practice questions): Panel type selection by application, fastener spacing for screws vs. nails, finish level requirements for different surfaces, and taping sequence.
• Siding (13 practice questions): Material identification, weather-resistive barrier requirements, exposure and coursing calculations, and vinyl siding fastening rules.

Across all topics, we offer 402 practice questions in our full question pool — drawn from the same subject areas as the real exam.

Required Study Materials

Because the Louisiana carpentry exam is open book, your references are tools — invest in them and learn them well.

Required by the exam bulletin:

• OSHA 29 CFR 1926 — The federal OSHA construction standards. Every safety question traces back here. Tab the fall protection, scaffolding, and ladder sections.

• Finish Carpenter's Manual — Covers door and window trim, moldings, stairs, and wall treatments in detail.
• IBC 2021 — The International Building Code, 2021 edition. Required for stair dimensions, structural minimums, and more. Note: only the 2021 edition is permitted for the IBC — not newer editions.

Bring your own copies on exam day. You are responsible for having all required references with you at the testing center.

Study Tips for the Louisiana Carpentry Practice Exam

Master your references before you walk in. On an open-book exam, the winners aren't the smartest people in the room — they're the fastest at finding answers. Buy the required books, then highlight, tab, and index them until you can land on any topic in seconds. That speed is what separates a pass from a fail.

Practice under a real clock. Two hours sounds like plenty until exam-day nerves slow you down. Use timed practice sessions to build your pacing. The goal is to move steadily without burning too long on a single question. Our full practice exam mirrors the real format — 60 questions, 120 minutes — so by test day, it feels routine.

Use elimination on tough questions. Rule out the options you know are wrong before choosing. Narrowing to two choices sharply improves your odds even when you're unsure.

Start free, then go deep. Our free practice exam gives you 10 questions with no account or payment required — a quick way to gauge where you stand. When you're ready for serious prep, the full paid exam matches the real test's length, timing, and topic breakdown, and gives you a score breakdown by topic so you can spot weak areas fast.

Focus your study time where the exam does. Rough Carpentry and Formwork is 45% of the test. Finish Carpentry is another 23%. Master those two sections first.
