NV-C15 Pass Rate 2026: What the Data Shows

The Pass Rate Reality: What Nevada Actually Publishes

Anyone searching for a specific NV-C15 pass percentage for 2026 will run into the same wall: the Nevada State Contractors Board and PSI do not publish a public pass/fail rate for the C-15 Roofing and Siding Contractor trade exam. That's different from some other trade credentials that release annual scorecards. What we can work with instead is the actual scoring structure of the exam itself, which is documented in the PSI candidate bulletin dated March 25, 2026 - and that structure tells you far more about your real odds than a headline percentage ever could.

Instead of chasing a number that isn't officially reported, the more useful question is: what does the exam's design tell you about difficulty and where candidates are most likely to lose points? That's what this article breaks down, using only the documented facts about the exam blueprint, scoring, and policy.

How the 75% Passing Threshold Actually Works

The C-15 trade exam blueprint is straightforward on paper: 60 scored multiple-choice questions, delivered by computer, with 120 minutes on the clock. You need 45 correct answers - exactly 75% - to pass. There's no partial credit, no domain-by-domain minimum, and no weighted scoring across the nine content areas. A correct answer on Photovoltaic Systems counts exactly the same as a correct answer on Steep Roofing.

What complicates the math slightly is that PSI is permitted to insert between 1 and 10 unscored experimental questions into the same test session, within the same 120-minute window. You won't know which questions are experimental, so every question has to be treated as if it counts. This means your actual question count on test day could be anywhere from 61 to 70, but your pass/fail outcome is still calculated against the fixed 60 scored items and the 45-correct threshold.

For a deeper breakdown of exactly what the 45/60 threshold means in practice, including how it compares to the raw scored-question count, see NV-C15 Passing Score 2026: Exactly What You Need to Pass.

Domain Weighting: Where the Questions Actually Come From

Because there's no published pass rate, the blueprint's domain weighting is the closest thing to "data" a candidate can act on. The C-15 exam pulls its 60 scored questions from nine content areas, and they are not weighted evenly:

Steep Roofing alone accounts for over a quarter of the entire scored exam. A candidate who is strong across the other eight domains but shaky on shingle, tile, and slope-related steep roofing content is disproportionately exposed, simply because that domain carries so many more questions than any other single area. This is the single most important structural fact bearing on your outcome - more relevant than any generic pass-rate statistic would be.

The remaining eight domains split the other 44 questions unevenly across Roofing Substrates, Roofing Repairs, Elastomeric Roofing, Built-up Bituminous Roofing, Sheet Metal and Flashing, Siding, Photovoltaic Systems, and Safety. A full walkthrough of how each of these nine areas is tested - including the kinds of scenario-based questions PSI uses - is covered in NV-C15 Exam Domains 2026: Complete Guide to All 9 Content Areas.

Retakes, Waiting Periods, and the Three-Failure Void

The retake structure is where the exam's real-world difficulty shows up, even without a published pass rate. If you fail, Nevada requires a two-week wait before you can sit again - and the fee schedule for a retake mirrors the original fee structure. More significantly, three failed attempts voids the entire application, meaning a candidate who fails three times doesn't just retake the exam - they have to restart the licensing application process from scratch through the Nevada State Contractors Board.

This time constraint is one reason candidates should not treat the exam casually or assume they can "test the waters" with a light-prep first attempt. If you're unsure whether your current knowledge is exam-ready, a structured difficulty assessment can help you calibrate before you spend a testing slot - see How Hard Is the NV-C15 Exam? Complete Difficulty Guide 2026 for a breakdown of where candidates typically underestimate the material.

Who Tends to Struggle - and Why

Because Nevada doesn't publish demographic or pass-rate breakdowns, this section is necessarily qualitative - but the exam's own design points to two recurring risk patterns among candidates pursuing this license.

• Specialists in one roofing system. A candidate whose field experience is heavily concentrated in, say, built-up bituminous roofing or siding installation may be under-prepared for the Steep Roofing domain's 16-question weight, even with years of solid on-the-job experience elsewhere.
• Candidates relying only on field memory for the open-book portion. The exam allows the 2018 International Building Code as an open-book reference, but NRCA manuals, OSHA materials, and other listed references are study-only - they cannot be brought into the testing room. Candidates who assume they'll "look it up" on test day for anything beyond the IBC are caught off guard.
• Candidates who ignore the annotation rules. Pre-exam highlighting, underlining, and permanent tabs in the open-book reference are allowed, but handwritten notes made before or during the test and any added loose papers are prohibited. Preparing your reference material incorrectly can cost you valuable time during the 120-minute window.

None of this requires guesswork about a mystery pass rate - it's simply a matter of aligning your preparation with the documented domain weights and reference rules rather than general roofing-trade knowledge alone.

Fee Mechanics That Affect Your Attempts

The financial structure around the exam also shapes how candidates approach retakes. Candidates pay $95 for a single examination portion, or $140 to sit for both the trade exam and the separate Contractor Management Survey (CMS) portion together. Retakes follow the identical fee schedule - there's no discount for a second attempt, which is one more reason the two-week wait and three-failure void matter financially, not just procedurally.

These exam fees sit inside a larger licensing cost picture that includes a $300 application fee, and $600 for initial licensing plus the same $600 at biennial renewal, with Residential Recovery Fund charges billed separately. A full cost breakdown, including how the CMS portion factors into your total spend, is available in NV-C15 Certification Cost 2026: Complete Pricing Breakdown.

Before you can even schedule, Board approval is required, and the underlying eligibility is tied to four years of relevant journey-level, foreman, supervisory, or contractor experience within the preceding fifteen years (approved education can substitute for up to three of those years). If you're still confirming whether you qualify, review NV-C15 Requirements 2026: Eligibility, Prerequisites & How to Qualify before worrying about pass-rate strategy at all.

A Domain-Based Prep Timeline

Given that Steep Roofing carries 16 of 60 questions and no single official pass-rate figure exists to benchmark against, the most reliable strategy is to weight your study time the same way PSI weights the exam. A four-week runway built around the domain list looks like this:

Running full-length timed practice sessions on our practice test platform is the closest you can get to simulating the actual pressure of the 120-minute, 60-to-70-question format before you spend a real attempt fee. Repeated exposure to the Steep Roofing-heavy question mix on the practice site is far more useful than any generic pass-rate number would be.
