Alabama Carpentry and Framing Contractor — Practice Exam

What This Practice Exam Covers

The Alabama Carpentry and Framing Contractor licensing exam consists of 60 questions answered in 180 minutes, with a passing score of 70% (42 correct). The exam tests knowledge across six topic areas: Estimating and Plan Reading, Layout, Walls, Floors and Stairs, Roofs, and OSHA Safety.

This practice exam gives you two options:

• Free practice exam: 10 questions per attempt, drawn from a limited pool. You can retake it as many times as you like to get comfortable with the question format and style before committing to full preparation.
• Full practice exam: Mirrors the real exam — 60 questions, 180-minute time limit. Questions are drawn from a pool of 248+ items, so every attempt delivers a unique set. No two attempts will be identical. All questions are built around the exact topic areas and subtopics defined by the official test provider.

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

What You'll Be Tested On

Estimating and Plan Reading — 9 items

This topic is more calculation-heavy than it first appears. You need to read span tables for headers, girders, joists, and rafters — not just locate numbers, but apply the right table for the member type and loading condition. Board-foot calculations from nominal dimensions are common; remember that nominal and actual dimensions differ, and board feet are calculated from nominal size. Expect to estimate framing material quantities for walls (stud count, top and bottom plates, headers), floors, and roofs given a set of dimensions. You also need to read architectural plan views, elevations, and section views, and correctly interpret standard symbols and abbreviations on drawings. Scale drawing questions require you to apply an architect's scale — for example, measuring a dimension from a ¼″ = 1′-0″ plan and converting it to actual feet.

Layout — 7 items

Layout questions test the practical mechanics of setting up a job site, not theory. You must know the purpose and operation of builder's levels, transits, theodolites, laser levels, and GPS instruments — the NASCLA/Carpentry Reference Chapter 9 section on Types of Instruments covers these distinctions. Questions cover the step-by-step procedure for setting up and leveling a transit over a station mark, laying out right angles (including the 3-4-5 method), and establishing building corners with batter boards. Differential leveling — measuring differences in elevation using rod readings — appears here. Know how to calculate elevation differences from backsight and foresight rod readings, and understand what "overdig" means during excavation.

Walls — 14 items

Walls is the heaviest topic on this exam. Expect questions on stud size, height, and spacing, as well as the full range of braced wall panel requirements under IRC Section R602.10. This includes allowable offsets from braced wall lines (IRC Section R602.10.1.2), bracing methods, and minimum panel lengths. Header and girder span questions require you to apply the correct table for the opening width, number of stories, and tributary load. Drilling and notching rules under IRC Section R602.6.1 test specific limits — you must know when a hole or notch in a stud or top plate is code-compliant versus prohibited. Fastening schedule questions pull from IRC Table R602.3(1) and similar tables. Wall anchorage and seismic provisions under IRC Sections R602.11.1 and R602.11.2 also appear.

Floors and Stairs — 13 items

Floor framing questions cover the full system: posts, girders, sill plates, joists, and subfloor panels. Joist span table questions (IRC Table R502.3.1(2) and related tables) require selecting the correct species, grade, and spacing to meet a given span. Subfloor questions address panel thickness, fastening schedules, and glue-nailing requirements per Section R503.2.3. Special conditions — floor openings, bearing walls, cantilevers, and doubled joists for bathroom framing — each carry specific rules under Sections R502.10, R502.4, and R502.7.1. Stair questions are code-specific: maximum riser height, minimum tread depth, headroom clearance, stair width, and baluster spacing under IRC Sections R311.7.5.1, R311.7.5.3, and R312.1.1. Know the numbers cold — the exam will test one dimension at a time.

Roofs — 12 items

Rafter sizing questions require applying span tables using the correct species, grade, spacing, and roof slope. Ridge board versus ridge beam distinctions matter: a ridge beam requires specific support conditions. Know the roles of collar ties, purlins, purlin braces, and ceiling joists — including that purlin struts must slope no less than 45 degrees from horizontal per 2021 International Building Code Section 2308.7.7. Roof sheathing installation, nail spacing, and panel identification are tested. Roof covering questions address minimum slopes for asphalt shingles, wood shakes, built-up roofing, and other materials. Ventilation requirements under International Residential Code Section R806.2 and attic access requirements under Section R807.1 round out this section.

OSHA Safety — 5 items

Five questions, all drawn from 29 CFR 1926. Fall protection thresholds, guardrail height requirements under §1926.502(b)(1), and personal fall arrest system rules under §1926.502(d)(16) are commonly tested. Know employer and employee rights, PPE obligations under §1926.28(a), and the definition of a "competent person" under §1926.32(f). Ladder and stairway safety under §1926.1051(a), hazard communication requirements, and first aid provisions under §1926.50(c) and §1926.50(d)(2) all appear in this block.

Worked Sample Questions

Question 1 — Walls

In wood-frame construction, braced wall panels shall be permitted to be offset how far from the designated braced wall line?

• A. 6 feet
• B. 8 feet
• C. 2 feet
• D. 4 feet ✓

Why D is correct: IRC Section R602.10.1.2 sets a clear limit: braced wall panels may be offset up to 4 feet from the designated braced wall line. This is a specific number the exam returns to repeatedly. Candidates who confuse this with stud spacing or other IRC dimensions will pick 2 feet or 6 feet. The answer is a direct code lookup — there is no calculation involved.

Question 2 — Floors and Stairs

A carpenter wants to drill a hole through a prefabricated wood I-joist for a plumbing pipe. When is this permitted?

• A. Only when the hole does not exceed one-third the depth of the joist
• B. Only when permitted by the manufacturer's recommendations or a registered design professional ✓
• C. Any time the hole is located in the middle third of the span
• D. Only when the hole is at least 2 inches from the top or bottom flange

Why B is correct: Section R502.8.2 treats engineered wood products differently from sawn lumber. Dimensional lumber has specific drilling and notching limits, but I-joists are proprietary structural members — the flange is the primary load-carrying element and any penetration must be evaluated per the manufacturer's published tables or by a registered design professional. Choices A, C, and D describe rules that apply to sawn lumber, not I-joists.

Question 3 — Roofs

What is the minimum slope from the horizontal required for purlin struts (braces) that support purlins in a roof framing system?

• A. 30 degrees
• B. 35 degrees
• C. 60 degrees
• D. 45 degrees ✓

Why D is correct: Per 2021 International Building Code Section 2308.7.7, purlin struts shall slope no less than 45 degrees from horizontal, and their unbraced length may not exceed 8 feet. Struts at shallower angles cannot adequately transfer the load they carry. This is a numerical minimum that the exam tests precisely — 30 or 35 degrees is wrong, and 60 degrees exceeds the minimum but the question asks for the floor, not the ceiling.

How to Read Your Score

The passing threshold is 70% — 42 out of 60 questions correct. Your first practice attempt is best treated as a diagnostic: it tells you where your knowledge is solid and where it has gaps, not whether you will pass or fail.

A score below 60% on your first attempt is normal and not a reason for concern — it means the practice exam is doing its job. A score between 60% and 69% is close but not close enough; candidates who score in that band on practice exams often find the real exam harder because unfamiliar question phrasing adds pressure. You want a consistent 75%+ on the full 60-question practice before sitting for the real exam.

Use your topic-by-topic breakdown strategically. Walls carries 14 items and Floors and Stairs carries 13 — together that is 45% of the exam. Improving your accuracy on those two sections has more impact than fine-tuning your OSHA knowledge. If Layout questions are costing you points, go back to the NASCLA/Carpentry Reference Chapter 9 procedures and work through the step-by-step setup sequences. Every retake of the full practice exam draws a new set of 248+ questions, so you are not just memorizing the same items.

Where Candidates Lose Points

Span table errors are the single biggest point drain. Candidates select the right table but use the wrong column — confusing live load versus total load, or reading the wrong spacing row. Slow down and verify every variable before reading across.

Board-foot calculations trip up candidates who use actual dimensions instead of nominal. A 2×10 is calculated as 2 inches × 10 inches for board feet, not 1.5 inches × 9.25 inches.

Drilling and notching rules require distinguishing between sawn lumber and engineered wood products. The rules in Section R502.8.1 (sawn joists) do not apply to I-joists under Section R502.8.2.

Stair dimensions — riser height, tread depth, headroom — are tested as exact code numbers. Candidates who remember "about 7 inches" instead of the exact maximum will miss these.

Braced wall panel questions require knowing both the offset limit (IRC Section R602.10.1.2) and the minimum panel length requirements, which vary by bracing method. Conflating these two produces wrong answers.

OSHA questions punish candidates who haven't read the specific CFR thresholds. Guardrail height, fall protection trigger heights, and first-aid provider ratios are all precise numbers — approximations won't pass.

Finally, time management on the Walls and Floors sections matters. At 3 minutes per question average, a candidate who spends 6 minutes untangling a span table early in the exam may be rushing through stair code questions at the end.
