How to Pass the California C-6 Cabinet, Millwork and Finish Carpentry Contractor Exam
To prepare for the California C-6 Cabinet, Millwork and Finish Carpentry exam, study the current CSLB outline by section, not just by job experience. Begin with a baseline, give extra attention to Cabinet Installation (25% of the outline) and other weak high-weight areas, then practice mixed scenarios until you can explain the method behind each answer.

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 (20%)
CSLB lists planning cabinetry and millwork projects, estimating cabinetry and millwork projects. Work from a plan or scope sheet: mark assumptions, units, quantities, dependencies, and any information that must be confirmed before estimating.
Cabinetry and Millwork Fabrication (24%)
CSLB lists milling cabinetry and millwork, assembling cabinetry and millwork, storing cabinetry and millwork, transporting cabinetry and millwork. Sketch the sequence from preparation through inspection or closeout. For each step, name the prerequisite, a common failure point, and a check before proceeding.
Cabinet Installation (25%)
CSLB lists demolishing old cabinets, identifying possible hazardous materials, job site preparation, installing cabinets, 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.
Millwork Installation (16%)
CSLB lists installing millwork, installing stairs and mantels, refacing cabinets and millwork, installing windows and doors. Sketch the sequence from preparation through inspection or closeout. For each step, name the prerequisite, a common failure point, and a check before proceeding.
Worker and Job Site Safety (15%)
CSLB lists personnel safety, job site safety, recycling and disposing of materials. 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 Cabinet Installation (25%) and Cabinetry and Millwork Fabrication (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-6 Cabinet, Millwork and Finish Carpentry example
Question: A wall measures 120 in. A layout uses a 36-in. base cabinet, a 30-in. range opening, and two 24-in. cabinets. How much width remains for fillers and clearances?
Answer: 6 in.
Why: 36 + 30 + 24 + 24 = 114 in.; 120 − 114 = 6 in. Verify appliance and installation clearances separately.
