The Mississippi Carpentry licensing exam consists of 60 questions answered in 120 minutes, with a passing score of 70% (42 correct answers). The exam tests seven topic areas, from OSHA safety regulations through finish carpentry and drywall installation.

This practice test is available in two formats. The free practice exam gives you 10 questions per attempt drawn from a limited pool. You can retake it as many times as you like — it costs nothing and gives you a genuine feel for question style, difficulty level, and topic emphasis before you commit to anything.

The full practice exam mirrors the real test exactly: 60 questions, 120-minute time limit, scored to the same 70% threshold. Questions are drawn from a pool of 584 items, so no two attempts are identical. Every question is built from the official exam topic blueprint provided by the test provider, making it the most efficient way to identify gaps and measure real readiness.

Start with the free exam, use your score to locate weak spots, then move to the full exam for targeted, timed practice.

7 topics

Safety 6 Items

Safety carries six questions, making it a meaningful slice of your score. Expect questions drawn directly from 29 CFR 1926, the OSHA construction safety standard. You need to know employer and employee responsibilities under 29 CFR 1926.20 and 1926.21, including the requirement that employees be trained to recognize and avoid unsafe conditions (29 CFR 1926.21(b)(2)). Fall protection questions are specific: the standard trigger heights, acceptable fall protection systems, and guardrail specifications under 29 CFR 1926.501 and 1926.502. Fire prevention questions test extinguisher classifications and placement rules (29 CFR 1926.150). PPE questions ask you to select the correct equipment for a described hazard — not just name it, but match it to the exposure. Electrical grounding, noise exposure limits under 29 CFR 1926.52, and scaffold fall protection under 29 CFR 1926.451 also appear. Know the numbers: heights, decibel limits, bolt diameters, spacing maximums.

Insulation 1 Item

One question means it will likely test something precise and testable. Focus on R-value basics — what R-value measures, how it relates to insulation effectiveness, and how different insulation types compare. Know the four main forms: batts, loose-fill, rigid board, and spray-foam. Understand vapor retarders — what they are, where they go relative to the warm side of the wall, and the difference between Classes I, II, and III. Crawl-space and attic ventilation requirements and radiant-heat barriers with their emissivity ratings also appear in the question pool.

Windows and Doors 3 Items

Three questions cover window and door components, installation, and code. For windows, you need to know operating types (casement, double-hung, awning, hopper, sliding), component terminology (jamb, sill, head, stool, apron, rough opening), and egress requirements including minimum net clear opening dimensions and maximum sill height. Energy terms — U-factor, Solar Heat Gain Coefficient (SHGC), Low-E glazing — appear regularly. Rough opening sizing (frame dimension plus clearance) is a calculation you should be able to do. For doors, know the difference between fire-rated door assemblies, pre-hung installation sequence, and pocket door framing. IBC Section 2406.4.2 governs hazardous locations requiring safety glazing.

Rough Carpentry and Formwork 27 Items

This is the heaviest topic by far — 27 of 60 questions, nearly half the exam. Mastery here is non-negotiable for passing.

Floor framing: Know posts, girders (including built-up girder construction), sill plates, floor joists, and subfloor panels. Anchor bolt requirements — ½-inch minimum diameter, 7-inch embedment, 6-foot maximum spacing — come directly from IBC Section 2308.3.1.

Wall framing: Know every member by name: king stud, trimmer stud, cripple stud, header, double top plate. Header sizing for openings, and how to calculate rough opening dimensions. Refer to IBC Table 2308.4.1.1(2) for header spans.

Roof framing: Common rafter layout using the framing square, unit rise, unit run, total run, rafter length. Ridge board sizing and ceiling joist connections. Rafter notch (bird's-mouth) geometry.

Foundation and formwork: Concrete and masonry foundation wall requirements, footing dimensions, and formwork construction per IBC Sections 1905–1907 and 1907.1.

Roof trusses: This is its own sub-exam. The BCSI guidelines (BCSI-B1 through B5) govern handling, installation tolerances, temporary and permanent bracing, bottom chord lateral restraint, and damage repair procedures. Expect specific questions about spacing of temporary lateral bracing, what constitutes reportable truss damage, and who must approve repairs.

Finish Carpentry 14 Items

Fourteen questions make this the second-heaviest topic. Stair building dominates: know every part (stringer, riser, tread, nosing, newel post, baluster, handrail, skirtboard) and the code limits — maximum riser height, minimum tread depth, minimum headroom, handrail height and graspability. The riser-tread rule of thumb appears regularly. Know both cut-stringer and cleat-stringer construction sequences step by step, including how to lay out a stringer with a framing square and stair gauges.

Molding and trim covers profile types, coping vs. mitering inside corners, and the block-and-plinth door casing installation sequence. Door rosettes and their purpose in casing layout also appear (Carpentry & Building Construction, Section 26.2).

Drywall 7 Items

Seven questions cover drywall panels, fasteners, finishing, and estimating. Know panel types cold: standard, Type X fire-code (5/8-inch, 45-minute rating), Type C, moisture-resistant (MR/green board), and where each is required. Fastener questions test Type-W vs. Type-S screw applications, proper dimple depth, and spacing (field vs. edge). Joint compound questions distinguish setting-type (chemical cure, cannot be re-wet) from drying-type (water evaporation, sandable). Know the three-coat taping sequence for flat joints and inside/outside corners. Estimating questions require you to calculate panel count from room square footage, then derive fastener quantities and joint tape length. Corner bead, bullnose bead, and J-trim installation and purpose are tested.

Siding 2 Items

Two questions, but they are specific. Wood bevel siding layout requires you to understand story pole construction, exposure calculation, and coursing. Shingle siding coursing styles — single, double, ribbon, and decorative — each have distinct characteristics. Vinyl siding fastening requires knowledge of nail slot center placement, expansion gap requirements, and J-channel use. Fiber cement handling includes silica dust exposure controls and approved cutting methods. Moisture prevention — building paper, housewrap, flashing, and drainage plane continuity — ties directly to the exam's siding subtopics.

3 questions

Question 1 — Rough Carpentry and Formwork

In conventional light-frame construction, foundation plates or sills shall be bolted to the foundation with steel bolts having a minimum diameter of what size?

  • A. 3/4 inch
  • B. 1/2 inch
  • C. 3/8 inch
  • D. 5/8 inch

Correct Answer: B — 1/2 inch

Per IBC Section 2308.3.1, sill plates must be anchored with bolts of at least ½-inch diameter, embedded not less than 7 inches into concrete or masonry, and spaced no more than 6 feet on center. The exam often presents all four options as plausible-sounding bolt sizes. The trap is confusing this with post-base anchor bolt specs or carriage bolt sizes used elsewhere in framing. Commit the three numbers — ½ inch, 7 inches, 6 feet — as a set.


Question 2 — Finish Carpentry

You are a finish carpenter installing a block and plinth door casing. In what order should the components be installed?

  • A. Side casings first, then corner blocks, then plinths, then head casing
  • B. Head casing first, then plinths, then side casings, then corner blocks
  • C. Plinths first, then side casings, then head casing, then corner blocks
  • D. Corner blocks first, then side casings, then plinths, then head casing

Correct Answer: C — Plinths first, then side casings, then head casing, then corner blocks

The sequence follows the logic of the assembly: plinths sit on the finish floor and establish the base reference, so they go first. Side casings are then cut to run from plinth to the corner block position. The head casing bridges the two side reveals. Corner blocks fill the square where head and side casings meet — they go last because they cover the joint. Installing in any other order creates alignment problems that cannot be corrected without removal. Source: Finish Carpenter's Manual (1993), Door Trim chapter, Block and Plinth Door Casing section.


Question 3 — Drywall

What is the primary purpose of installing corner bead on outside drywall corners?

  • A. To serve as a vapor retarder at wall intersections
  • B. To provide structural support for the framing members at corners
  • C. To reinforce and protect the corner while providing a smooth edge for finishing
  • D. To eliminate the need for joint compound at outside corners

Correct Answer: C — To reinforce and protect the corner while providing a smooth edge for finishing

Outside drywall corners are the most vulnerable point in any finished wall — they take impact and are difficult to finish cleanly by hand. Corner bead (vinyl or metal) solves both problems: it reinforces the fragile gypsum edge against damage and gives the finisher a straight, consistent guide edge for feathering joint compound. It does not eliminate compound — multiple coats are still applied over it. Source: Carpentry And Building Construction, Chapter 32, Trim Accessories section.

The passing threshold is 70%, which means 42 correct answers out of 60. On the full practice exam, treat your first attempt as a diagnostic, not a verdict. Reading under time pressure is a different skill than studying at your own pace.

What matters is your topic-by-topic breakdown. A low score on Rough Carpentry and Formwork (27 items) has far more impact on your total than a weak result in Insulation (1 item) or Siding (2 items). Prioritize accordingly.

A practice score in the low 70s usually means you are close but not ready — one bad topic cluster on exam day could drop you below the line. Aim for consistent 80%+ performance across multiple attempts before scheduling the real exam. A score in the 60s means two or three topic areas need focused review, not just additional practice attempts. Use the explanations on missed questions to find the specific rule or calculation you are misapplying, then return to the relevant code section or textbook reference before retaking.

Rough Carpentry and Formwork demands your closest attention, simply because 27 questions means every error here hits hard. Common losses: confusing rafter layout terms (unit rise vs. total rise, unit run vs. total run), misidentifying trimmer vs. king stud in wall framing diagrams, and applying the wrong IBC table for header spans.

Truss questions trip up candidates who know framing but haven't studied the BCSI guidelines. The BCSI-B1 through B5 documents contain very specific numbers — bottom chord lateral restraint spacing, installation tolerances, maximum out-of-plumb — that do not appear in standard framing references.

Finish Carpentry stair calculations produce errors when candidates mix up riser height and tread depth, or apply the wrong rounding direction when dividing total rise by a trial riser count.

Drywall estimating loses points when candidates forget to account for panel orientation (horizontal vs. vertical application changes cut patterns), or confuse Type-W and Type-S screw applications.

Safety questions are frequently missed by experienced tradespeople who rely on field habit rather than the specific 29 CFR 1926 numbers. The exam asks what the regulation says, not what most job sites do.

Finally, time management: 120 minutes for 60 questions is 2 minutes per question. The heavy Rough Carpentry section can consume disproportionate time if you linger on truss or rafter calculations — practice pacing.
