LA-RRC Passing Score 2026: Exactly What You Need to Pass

The Passing Score Number

If you're preparing for the Louisiana Residential Roofing Contractor Exam, the number that matters most is 70%. The Louisiana State Licensing Board for Contractors, working through its testing vendor PSI, requires candidates to answer at least 70% of the scored questions correctly to pass. Since the exam contains 50 scored questions, that means you need to get 35 or more correct to earn a passing result under subclassification 9.2 of Residential Construction.

That threshold is fixed. There's no curve, no adjustment for a "hard" test day, and no partial credit for questions you leave blank. Every scored item counts the same, whether it comes from Domain 1 (Materials) or Domain 5 (Safety). Understanding this simple math early lets you set realistic study goals instead of guessing at what "good enough" looks like.

How the PSI Exam Is Scored

PSI administers the LA-RRC exam as a computer-delivered, open-reference, multiple-choice test. Two details about scoring trip up candidates who haven't read the fine print:

• Unscored experimental questions. PSI may insert 1 to 10 additional questions that do not count toward your final score. These are indistinguishable from scored items, so you should treat every question on screen as if it matters - because you can't tell which ones don't.
• Time pressure compounds error risk. With a 2-hour limit covering up to 60 total questions (50 scored plus possible experimental items), you have roughly two minutes per question on average. Rushing at the end increases the odds of missing easy points you should have banked early.

Because you can't isolate which questions are experimental, the only reliable strategy is consistent accuracy across the entire test. For a deeper look at how PSI structures difficulty and pacing, see our guide on how hard the LA-RRC exam really is.

Exam Format You'll Face

Registration for the exam costs $125, and the test itself is delivered on computer at a PSI testing center. It's open-reference, meaning you're allowed to bring approved printed materials into the exam room - but only in specific, controlled ways covered below. Every question is multiple-choice, and there's no essay, calculation-input, or scenario-simulation component beyond selecting the best answer from the choices given.

Domain Breakdown and Where Points Live

The 50 scored questions are distributed across five content domains. While the board doesn't publish a rigid percentage-per-domain formula for candidates to memorize, it's well established that Installation of Roof Coverings is the largest domain by question volume. That single fact should shape how you allocate study hours.

For a granular breakdown of subtopics inside each domain, see LA-RRC Exam Domains 2026: Complete Guide to All 5 Content Areas. Since Installation of Roof Coverings carries the most weight, missing points there is the fastest way to fall below the 35-correct threshold - even strong performance in the other four domains may not offset gaps here.

Open-Reference Rules That Affect Your Score

One of the most misunderstood aspects of the LA-RRC exam is what "open-reference" actually permits. You are not allowed to bring loose notes, printouts, or binders with removable pages. Instead, the approved references are specific bound texts:

• The 2021 International Building Code
• OSHA 29 CFR Part 1926
• Roofing Construction and Estimating by Daniel Atcheson
• The NRCA Roofing Manual: Steep-Slope Roof Systems

You may highlight, annotate, index, and permanently tab these bound books before you arrive at the testing center. That preparation work happens in advance - once the exam session begins, no writing is allowed, and loose pages are prohibited entirely. This means your tabbing strategy is effectively part of your score. A well-indexed copy of the NRCA Roofing Manual can save you critical minutes on Installation of Roof Coverings questions, while a tabbed OSHA reference speeds up Domain 5 lookups.

Relying entirely on open-reference lookups during the exam is risky given the 2-hour limit - flipping through books for every question will burn your clock fast. The references are a safety net for uncertain items, not a substitute for knowing the material. Our LA-RRC Study Guide 2026 walks through how to balance memorization with reference reliance.

Mapping Study Time to the Passing Threshold

Because the passing score is fixed at 70%, your prep should be diagnostic, not just repetitive. Use practice questions to find out exactly which domains cost you points, then concentrate remaining study time there rather than re-reviewing material you already know cold.

Timed practice matters because pacing failures - not knowledge gaps - sink otherwise-prepared candidates. Practicing under the same 2-hour constraint you'll face at the PSI center builds the instinct to move on from a hard question rather than losing five minutes to it.

Why 70% Matters More Under Act 422

The passing score isn't just an academic hurdle anymore. Under Act 422, effective January 1, 2026, any residential roofing project valued at $7,500 or more requires the contractor to hold the Residential Roofing or Residential Construction classification - and that requires passing this trade exam. Roofing contractors who previously operated below that threshold without a license now have a hard compliance line to cross.

Separately, Act 757 raises the residential liability-insurance minimum to $500,000, effective August 1, 2026. While insurance isn't part of the exam content itself, it reflects the same regulatory tightening: Louisiana is raising the bar for who can legally perform residential roofing work, and the 70% passing score is the gatekeeper for that license.

This shift is also changing who's hiring for licensed roofing crews - established contracting companies, roofing subcontractors bidding larger residential jobs, and insurance-restoration firms all have incentive to employ licensed personnel who can legally sign for work above the new threshold. If you're weighing whether the credential is worth pursuing given these changes, see Is the LA-RRC Certification Worth It?

Before you schedule your exam, it's also worth confirming you meet the board's prerequisites - outlined in LA-RRC Requirements 2026: Eligibility, Prerequisites & How to Qualify - so your $125 fee isn't spent on an attempt you weren't yet eligible to sit for.
