California CSLB Exam Study Plan

California requires a separate Law & Business exam and a trade classification exam for most CSLB license paths. Both are typically closed-book through PSI โ€” focus on recall, scenario reading, and elimination rather than book tabbing.

Format: Closed-book (verify) Provider: PSI Authority: CSLB NASCLA: Not accepted

Reference list (study guides โ€” confirm with CSLB)

Book List Confidence: Medium โ€” CSLB exams are closed-book; use these as study references, not exam-day materials. Confirm your classification bulletin before purchasing.

Topic emphasis

  • Seismic detailing โ€” anchor bolts, shear wall nailing, cripple wall bracing
  • Wildfire hardening โ€” CBC/CRC Chapter 7A, ember-resistant vents
  • Title 24 Part 6 โ€” energy calculations, duct testing, acceptance forms
  • California labor standards โ€” prevailing wage, apprenticeship ratios, stop orders
  • Law & Business โ€” mechanics liens, workers' comp, payroll taxes, contracts, estimating

Suggested 30-day study plan

  1. Week 1 โ€” Confirm CSLB classification(s) and exam requirements; pull PSI bulletins; build a miss log by topic (code, safety, business law, labor).
  2. Week 2 โ€” Law & Business: lien law, workers' comp, payroll; daily timed scenario drills.
  3. Week 3 โ€” Trade content: seismic, wildfire, Title 24; short timed sets with immediate review.
  4. Week 4 โ€” Mixed timed simulations blending L&B + trade-style questions; schedule both exams after Notice to Appear; complete Live Scan.

Common California confusion

  • Two exams. Law & Business is separate from your trade classification exam โ€” use the B&L checker to confirm your path.
  • Closed-book. Do not buy code books expecting to bring them to PSI โ€” study for recall and application instead.
  • Notice to Appear first. CSLB must issue your notice before you schedule with PSI; Live Scan fingerprints are required.
  • Classification-specific trade exams. B, C, and specialty classifications test different domains โ€” match study to your exact classification.
