Louisiana Carpentry Licensing Exam — Practice Test Guide

What This Practice Exam Covers

The Louisiana Carpentry licensing exam consists of 60 questions answered in 120 minutes, with a 70% passing score (42 correct answers). Questions are drawn from seven topic areas covering safety regulations, rough framing, finish work, drywall, insulation, siding, and windows and doors.

This site offers two practice options:

• Free practice exam: 10 questions per attempt, drawn from a limited pool. You can retake it as many times as you want to get comfortable with the question format and difficulty level. It costs nothing and requires no account.
• Full practice exam (paid): 60 questions with a 120-minute timer — an exact mirror of the real exam experience. Questions are pulled from a pool of 402+ items, so every attempt delivers a unique set. No two attempts will be identical, which means repeated sessions expose you to new material each time. Questions reflect the exact topic distribution specified by the official test provider.

Start with the free exam to get your bearings, then use the full exam for serious, timed preparation.

What You'll Be Tested On

Safety — 6 Items

Safety is a rule-and-number topic. The exam asks you to recall specific thresholds, not general concepts. You must know the 6-foot trigger height for fall protection in residential and general construction, and what happens at that threshold. Personal fall arrest systems require knowledge of components (body harness, lanyard, anchor), deceleration distances, and maximum arresting force — the exam will test specifications, not just vocabulary. Guardrail systems require you to know top rail height (42 inches in general industry contexts), load capacity (200 lbs), and midrail placement. Scaffold safety covers maximum load ratings, platform plank requirements, access rules, and when fall protection is required on scaffolding (per 29 CFR 1926, §1926.451(g)(1)). Ladder safety questions target duty ratings (Type I, II, III), the 4:1 pitch rule, extension distances above a landing, and prohibited uses. Stairway requirements address riser height limits, minimum tread depth, handrail graspability, and stairrail height — specific numbers you can memorize cold.

Insulation — 1 Item

One question covers a broad subtopic range, so you cannot predict exactly where it lands. Know the R-value system — what R means, and approximate R-values for common insulation types (fiberglass batt, rigid foam, spray foam). Understand the forms of insulation: batts/blankets, loose-fill, rigid board, spray-foam. Know where insulation goes in the building envelope (walls, floors, ceilings, attics, foundations), including which surfaces get priority. Review vapor retarder function, perm ratings, and which side of the assembly the retarder goes on in a hot-humid climate like Louisiana. Crawl-space and attic net free area ventilation calculations and radiant heat barriers (emissivity vs. reflectivity) are also fair game per Carpentry And Building Construction, Section 31.1.

Windows and Doors — 3 Items

Three items spread across six subtopics means you need breadth. Know window operating types (double-hung, casement, awning, hopper, sliding) and their features. For door construction, distinguish solid-core from hollow-core and know when each is specified. Rough opening sizing is calculation-based — the RO is typically the door/window unit size plus clearance for shimming and framing. Know door hardware installation sequence: hinge placement, lockset boring, strike plate mortising. Weatherstripping types and their energy efficiency purpose appear in context questions. Egress window requirements are heavily testable: minimum net clear opening area (5.7 sq ft for most, 5.0 sq ft at grade), minimum clear opening height (24 in.), minimum clear opening width (20 in.), and maximum sill height (44 in. above floor).

Rough Carpentry and Formwork — 27 Items

This is nearly half the exam. Expect detailed, technical questions throughout. Platform-frame vs. balloon-frame construction differences are foundational — know which members run continuously in each system. Floor framing requires you to identify and understand sill plates, girders, posts, floor joists, bridging, and subfloor panel installation and nailing patterns per Carpentry and Building Construction, Section 15.2. Wall framing tests your ability to identify every member by name and function — king stud, trimmer stud, cripple stud, rough sill, double top plate — and calculate rough opening dimensions for headers. Wall sheathing covers structural vs. non-structural panels, diagonal bracing, and let-in bracing. Roof framing requires rafter layout math using unit rise, unit run, and the Pythagorean relationship; you must distinguish common, hip, valley, and jack rafters and know how each is laid out per Carpentry and Building Construction, Chapters 17 and 18. Roof truss handling draws from BCSI-B1 and B2: safe installation sequence, temporary lateral restraint, diagonal bracing requirements before sheathing is applied — expect true/false and scenario questions here.

Finish Carpentry — 14 Items

Second-heaviest topic. Door installation covers prehung door setting, shimming, hinge placement, and determining door hand (per the Finish Carpenter's Manual, Chapter 7). Casing and trim questions test reveal dimensions, back-cut angles, and the sequence for installing stool-and-apron window trim vs. picture-frame casing. Molding installation requires knowledge of coped vs. mitered joints — when to use each — and how crown molding spring angles affect cutting math. Wall treatments include tongue-and-groove wainscot layout and sheet paneling installation. Stair trim-out is heavily detailed: skirtboard installation sequence, tread/riser installation order, newel post anchoring, baluster spacing, and dovetail vs. pin-top baluster methods per Carpentry & Building Construction, Chapter 25. Finish flooring covers moisture content requirements for wood strip flooring, subfloor flatness tolerances, nail/staple fastening patterns, and the difference between strip, plank, and parquet installation methods.

Drywall — 7 Items

Know panel types (standard, moisture-resistant, fire-rated Type X, Type C) and when each is required. Fastener types matter: Type-S screws for steel framing, Type-W screws for wood framing (Carpentry And Building Construction, Chapter 32, Drywall Fasteners section). Know spacing rules — fasteners too close to panel edges cause cracking. Levels of finish (Level 0 through Level 5) are testable by definition: Level 0 is no finishing, Level 5 adds a skim coat over all surfaces. Joint treatment covers embedding tape in the first coat, feathering subsequent coats, and the difference between drying-type and setting-type compounds. Corner bead types (metal, vinyl, paper-faced) and their applications are tested. Fire-rated assemblies require knowing that Type X panels use treated gypsum core and are required for specific rated wall assemblies.

Siding — 2 Items

Know the main siding material types and how each is installed differently. Moisture protection is a common question area: building paper vs. housewrap function, flashing sequencing at openings, and drainage plane principles per Carpentry And Building Construction, Chapter 23. Wood bevel siding installation involves making a story pole, calculating exposure, and proper nailing (nail above the top of the course below, not through it). Wood shingle siding grading and double-coursing methods differ from bevel siding. Vinyl siding requires loose fastening to allow thermal expansion. Fiber cement is nailed differently from wood and requires specific clearances from grade.

Worked Sample Questions

Question 1 — Rough Carpentry and Formwork

Floor trusses should be braced as they are being installed to increase worker safety and to prevent the trusses from being damaged by sideways movement before the subfloor is laid.

A. TRUE ✓
B. FALSE

Correct Answer: TRUE

Floor trusses have almost no lateral resistance until the subfloor ties them together. Without temporary bracing during installation, sideways loads — from workers, wind, or simply leaning — can rack or topple them. Bracing each truss as it goes in is a sequencing requirement, not just a best practice. The truss fabricator provides specific bracing diagrams to follow. (Source: Carpentry and Building Construction, Section 15.1, Page 400)

Question 2 — Finish Carpentry

You are a carpenter installing a basement stairway where the lower end rests on a concrete floor. Since you cannot toenail into concrete, what component should you use to anchor the bottoms of the stringers?

• A. A metal saddle bracket bolted to the wall
• B. Lag bolts driven through the stringers into the concrete
• C. A kick plate fastened to the concrete ✓
• D. Concrete adhesive applied directly to the stringer ends

Correct Answer: C

A kick plate is a short piece of framing lumber that is screwed or nailed directly to the concrete slab. Once the kick plate is secured, the stringers can be toenailed into it — solving the problem of connecting wood framing to a concrete surface without an embedded anchor. Saddle brackets and adhesive are not the specified method; lag bolts into concrete require anchors and do not address the toenailing issue. (Source: Carpentry & Building Construction, Chapter 25 — Stairways)

Question 3 — Drywall

Which type of drywall screw is designed specifically for steel framing and features narrow threads?

• A. Phillips bugle-head screws
• B. Annular-ring screws
• C. Type-S screws ✓
• D. Type-W screws

Correct Answer: C

Type-S screws have narrow, closely spaced threads engineered to self-drill through light-gauge steel framing without pre-drilling. Type-W screws have coarser, wider threads designed to grip wood fibers aggressively. Mixing them up — using Type-W in steel — results in poor penetration and fastener failure. Neither type requires a pilot hole in normal drywall applications. (Source: Carpentry And Building Construction, Chapter 32, Drywall Fasteners section)

How to Read Your Score

The passing score on the real Louisiana Carpentry exam is 70% — 42 out of 60 questions correct.

Treat your first practice attempt as a diagnostic, not a verdict. A score in the 50s on your first full practice run is normal and tells you which of the seven topic areas need targeted review — not that you are unready overall. Use the topic-by-topic breakdown after each attempt to find your weak areas.

Here is a practical readiness benchmark:

• Below 65%: Significant gaps remain. Focus study on your two or three lowest-scoring topics before retesting.
• 65–72%: You are close, but scoring near the line on practice means you will likely be near the line on exam day — and pressure reduces performance. Keep drilling.
• 75% and above, consistently across multiple attempts: You are in a strong position. Use final sessions to eliminate any remaining weak subtopics.

Because the full practice exam draws from 402+ questions, each retake surfaces new items. This matters most for Rough Carpentry and Formwork (27 items on the real exam) — you need broad mastery of that topic, not familiarity with a fixed question set.

Where Candidates Lose Points

Misremembering specific numbers in Safety. The exam does not reward almost-right answers. Candidates confuse the guardrail top rail height (42 in.) with the stairrail height, or mix up the 4:1 ladder pitch rule with the 3:1 that applies elsewhere. Write these numbers down and drill them separately.

Rough Carpentry calculation errors. With 27 items, math mistakes compound. Rafter length calculations using unit rise and unit run, header sizing from span tables, and joist span limits are all tested. A missed step — forgetting to add the ridge board half-thickness to a rafter run, for example — costs a point even when the method is right.

Confusing truss bracing stages. BCSI documents distinguish temporary lateral restraint (installed during erection) from permanent diagonal bracing (installed before sheathing). Exam questions test whether you know which applies at which stage.

Finish Carpentry sequencing errors. Stair trim-out questions are detailed and procedural. Candidates who know the parts but not the installation order — especially tread/riser sequence and newel post anchoring — lose points on what should be straightforward questions.

Drywall screw and compound mix-ups. Confusing Type-S and Type-W screws, or mixing up setting-type compounds (which harden chemically) with drying-type compounds (which shrink as they dry), are among the most common single-point losses in the Drywall section.

Running short on time. 120 minutes for 60 questions is 2 minutes per question. The heavy Rough Carpentry section contains calculation items that can eat 4–5 minutes each. Practice pacing during timed full-exam runs before test day.
