How to Pass the California C-5 Framing and Rough Carpentry Contractor Exam
To prepare for the California C-5 Framing and Rough Carpentry exam, study the current CSLB outline by section, not just by job experience. Begin with a baseline, give extra attention to Structural Framing (38% of the outline) and other weak high-weight areas, then practice mixed scenarios until you can explain the method behind each answer.

Current CSLB C-5 Framing and Rough Carpentry exam outline
The official CSLB C-5 Framing and Rough Carpentry study guide applies to examinations scheduled on or after June 1, 2025. CSLB describes these percentages as approximate. The trade exam is closed book; check the current PDF and your exam notice before testing.
| Official section | Approximate weight | What to practice |
|---|---|---|
| Planning and Estimating | 17% | Project planning; Blueprints, specifications, and shop/field drawings; Estimating |
| Structural Framing | 38% | Formwork; Load and span; Bracing |
| General Framing | 21% | Flashing and weatherproofing; Siding, roofing, and flooring; Doors, windows, and stairs |
| Safety | 24% | Cal/OSHA requirements; EPA and AQMD regulations; Asbestos and environmental hazards |
Section-by-section study guide
Use the outline as a checklist, not a promise that every bullet gets an equal number of questions. After a diagnostic, spend extra time on weak high-weight sections.
Planning and Estimating (17%)
CSLB lists project planning, blueprints, specifications, and shop/field drawings, estimating, calculations. Work from a plan or scope sheet: mark assumptions, units, quantities, dependencies, and any information that must be confirmed before estimating.
Structural Framing (38%)
CSLB lists formwork, load and span, bracing, shear and diaphragm, among other topics. Sketch the sequence from preparation through inspection or closeout. For each step, name the prerequisite, a common failure point, and a check before proceeding.
General Framing (21%)
CSLB lists flashing and weatherproofing, siding, roofing, and flooring, doors, windows, and stairs, decks, porches, and gazebos, among other topics. Sketch the sequence from preparation through inspection or closeout. For each step, name the prerequisite, a common failure point, and a check before proceeding.
Safety (24%)
CSLB lists cal/osha requirements, epa and aqmd regulations, asbestos and environmental hazards, transportation and traffic control. For each scenario, identify the hazard, the first safe action, and which fact in the prompt changes the response. Verify technical requirements in the current applicable rules, not memory alone.
Two-, four-, and six-week study paths
Two weeks: Use this only if you already have broad recent experience and can practice daily. Diagnose on day one; spend the next several days on Structural Framing (38%) and Safety (24%); rotate through remaining sections; finish with a timed mixed set and a review of every miss or guess.
Four weeks: Week 1: read the official guide, take a baseline, and build an error log. Week 2: work the highest-weight weak sections using drawings, calculations, or installation sequences. Week 3: cover remaining trade sections and safety. Week 4: take timed mixed sets and revisit weak topics with fresh questions.
Six weeks: Add more depth to each field section and retest a week after first reviewing it. Reserve the last week for mixed practice, the error log, and test-day instructions. These are Peerless example schedules, not CSLB requirements.
Original worked C-5 Framing and Rough Carpentry example
Question: A rectangular frame measures 12 ft along one side and 16 ft along the other. What diagonal confirms a square corner?
Answer: 20 ft.
Why: The 3-4-5 relationship scaled by four gives 12-16-20. Field tolerances and the drawings still control.
This is an original study exercise, not a recalled CSLB question.

Frequently asked questions
What should I study first for C-5 Framing and Rough Carpentry?
Start with a diagnostic, then prioritize weak sections with larger approximate weights. Structural Framing is the largest section at 38%, but your own weak areas determine the order.
Is the C-5 Framing and Rough Carpentry trade exam open book?
No. The current CSLB study guide says no reference materials may be used during the exam.
Are these Peerless questions actual state-exam questions?
No. Peerless uses original study questions; this page is based on the public CSLB content outline.
Do I also need Law and Business?
CSLB describes a separate Law and Business exam for contractor-license applicants. Check the official requirements that apply to your application.
