NV-B Cheat Sheet 2026: One-Page Review of Must-Know Facts

Exam Snapshot

Before you touch a single practice question, lock these numbers into memory. The Nevada State Contractors Board's Class B trade examination is administered by PSI and consists of 80 multiple-choice questions across 11 content domains. You get 180 minutes, and you need 56 correct answers to reach the 70% passing threshold. There's no partial credit for "close enough" - it's a straight count of correct responses against the total.

The format is closed book, with one carve-out: code references that PSI's current content outline explicitly authorizes for the exam session. That means you can't bring your own annotated binder of notes, but you also don't need to memorize every code section verbatim - you need to know how to navigate the permitted reference quickly under time pressure. If you haven't already mapped out how each of the 11 areas is tested, the NV-B Exam Domains 2026: Complete Guide to All 11 Content Areas breaks down what each one actually covers.

Registration & Fees

PSI's fee structure is straightforward but easy to get wrong if you're scheduling exams separately. A single trade exam sitting costs $95. If you schedule the trade exam and the CMS (Contractor's Management Survey/exam) together, PSI charges a combined $140 - cheaper than paying for each separately, assuming you're ready for both at once.

Fees for the trade exam are distinct from what the Nevada State Contractors Board charges for licensure itself. Once you pass, the Board's application fee is $300, and the biennial license fee is $600. These are recurring costs tied to your two-year license cycle, not one-time exam costs. For a full breakdown of every dollar amount you'll encounter from registration through renewal, see NV-B Certification Cost 2026: Complete Pricing Breakdown.

Domain-by-Domain Cheat Sheet

Here's a compressed reference for all 11 domains. Use this as a final review, not a first introduction - if any of these feel unfamiliar, back up and work through the NV-B Study Guide 2026: How to Pass on Your First Attempt before exam day.

The Three Heaviest Domains

Concrete, Metals, and General Code, Plan Reading, and Estimating are tied as the largest domains on the exam. That means, statistically, more of your 80 questions will draw from these three areas than from Site Work, Masonry, or Nevada One Call. This doesn't mean you can skip the smaller domains - a single missed point across several thin domains adds up fast - but it does mean your review hours should be weighted toward these three.

If you want a deeper sense of how these weights translate into actual question difficulty and phrasing style, How Hard Is the NV-B Exam? Complete Difficulty Guide 2026 walks through what makes these three domains particularly demanding for first-time candidates.

Licensure Pathways & Substitutions

Passing the trade exam is only one piece of getting licensed. The Nevada State Contractors Board also requires Board approval, completion of the CMS, and a qualifying individual with four years of relevant experience earned within the prior 15 years. Approved education can substitute for up to three of those four years, but it cannot eliminate the experience requirement entirely.

There's also a substitution path worth knowing: a qualifying score on the NASCLA Accredited Examination for Commercial General Building Contractors can replace the Class B trade exam itself. This does not replace the CMS - you'll still need to complete that separately regardless of which exam route you take. For the complete rundown of eligibility rules, experience documentation, and qualifying individual requirements, see NV-B Requirements 2026: Eligibility, Prerequisites & How to Qualify.

Final-Week Review Plan

If you're in your last stretch before exam day, structure your remaining hours around domain weight rather than domain order. Here's a compressed schedule that assumes you've already completed full-length study earlier and are now consolidating.

Running a full-length timed simulation matters more for this exam than open-ended review, since the 180-minute limit and closed-book format both require pacing discipline you can only build through practice. You can run realistic timed sessions using the question bank at the main practice test site.

Common Last-Minute Mistakes

A few patterns show up repeatedly among candidates who don't pass on the first try:

• Ignoring the tie for largest domains. Some candidates spread study time evenly across all 11 domains instead of weighting toward Concrete, Metals, and General Code, Plan Reading, and Estimating.
• Misunderstanding "closed book." Candidates assume they can bring any code book, when only references named in PSI's current content outline are permitted.
• Confusing the CMS with the trade exam. These are separate tests with separate content - passing one doesn't substitute for the other, except in the specific NASCLA case noted above.
• Underestimating pacing. At roughly 2 minutes 15 seconds per question, spending five minutes deliberating on one estimating problem can cost you the questions at the end of the exam.
• Not knowing the passing threshold precisely. It's 56 of 80, not a rounded "about 70%" - see NV-B Passing Score 2026: Exactly What You Need to Pass for the exact math.
