- GARBC candidates must pass two separate exams - Residential-Basic (80 questions, 200 minutes) and Business and Law (50 questions, 120 minutes) - each at 70%.
- PSI does not publish a single official GARBC pass rate, so "the data" is really the exam's structure and rules, not a percentage.
- General Code and Construction Knowledge (22.5%) and Carpentry (20%) carry the most scoring weight of the eight domains.
- Exam approval lasts one year and permits three sittings before reapplication requirements kick in.
What the Published Data Actually Shows
If you searched for a hard "GARBC pass rate" number, here's the honest answer: the Georgia State Licensing Board for Residential and Commercial General Contractors and PSI, the administering testing body, do not publish a granular public pass rate breakdown for the Residential-Basic examination. What is publicly documented - and far more useful for your prep - is the exam's structure, scoring threshold, and retake mechanics. Those rules tell you exactly how much margin for error you have, which matters more than a headline percentage that may not even reflect your specific background or study approach.
Instead of chasing a phantom statistic, this article breaks down the concrete, verifiable factors that determine whether a given candidate passes: the two-exam structure, the 70% cutoff on each exam, the domain weighting inside the Residential-Basic test, and the retake rules that govern what happens if you fall short. For a broader look at exam difficulty itself, see How Hard Is the GARBC Exam? Complete Difficulty Guide 2026.
Two Exams, Two Separate Pass/Fail Hurdles
Licensure isn't decided by one test. Candidates must clear the 80-question Residential-Basic examination within a 200-minute limit and the separate 50-question Business and Law examination within a 120-minute limit. Each exam requires its own 70% score - passing one does not offset a weak score on the other. This dual-hurdle design is the single biggest reason a candidate's overall outcome can't be reduced to one pass rate figure: you're really facing two independent pass/fail events with different content, different pacing, and different failure modes.
Business and Law content is a different animal from the trade-heavy Residential-Basic exam, and candidates who cruise through job-site knowledge sometimes stumble on the administrative and legal material simply because they under-prepared for it. If you're mapping out a study plan, treat these as two separate campaigns rather than one combined effort. The GARBC Study Guide 2026: How to Pass on Your First Attempt walks through how to sequence preparation for both exams without shortchanging either one.
Key Takeaway
Budget separate study blocks for Business and Law rather than assuming Residential-Basic trade knowledge will carry over - the content, pacing, and question style differ enough that cross-over is limited.
Why Domain Weighting Matters More Than One Number
The Residential-Basic exam draws from eight domains, and they are not weighted evenly. That weighting is the most actionable "data" a candidate actually has, because it tells you where points are concentrated and where a knowledge gap will cost you the most.
General Code and Construction Knowledge - 22.5%
The single largest domain on the exam. Candidates need working familiarity with code-driven decision-making across a residential job, not just isolated facts.
- Heaviest-weighted domain - under-preparing here has the largest downside
Carpentry - 20%
The second-largest domain, reflecting the exam's residential-construction focus on framing, structural wood systems, and related carpentry practices.
- Combined with General Code, these two domains make up nearly 43% of the scored exam
Associated Trades - 12.5%
Covers the trade knowledge a general residential contractor needs to coordinate and oversee, even without performing the specialty work directly.
- Broad but shallower than Carpentry or General Code
Sitework, Footings and Foundation / Concrete and Concrete Reinforcement - 10% each
Two foundational domains covering the earliest phases of a residential build, each carrying equal weight.
- Together they account for a fifth of the exam
Roofing - 10%
A standalone domain matching the weight of Sitework and Concrete, underscoring that roofing knowledge is treated as a core competency, not an afterthought.
OSHA Safety - 8.75%
Job-site safety standards relevant to residential construction supervision.
Masonry - 6.25%
The smallest domain by weight, but still scored and still capable of tipping a borderline result.
For the full breakdown of what's tested inside each of these eight areas, see the GARBC Exam Domains 2026: Complete Guide to All 8 Content Areas.
The Retake Window: Three Sittings, One Year
Exam approval is valid for one year, and candidates get three sittings within that window before reapplication rules apply. This is a hard structural fact worth internalizing before you schedule your first attempt: it's not an unlimited-retry system, and it's not indefinite either. If your first attempt falls short, you have a limited runway to regroup, re-study, and sit again - not a full restart of the clock each time.
This retake structure changes how you should think about a "close" score. A candidate who misses 70% by a couple of points on Roofing or Masonry hasn't failed for lack of ability - they've failed for lack of targeted review in a lower-weighted domain. Because sittings are finite, it's worth treating each attempt as a real opportunity rather than a low-stakes practice round. For a detailed look at exactly what "passing" requires numerically, see GARBC Passing Score 2026: Exactly What You Need to Pass, and for scheduling logistics around your approval window, check GARBC Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
Where Candidates Typically Lose Points
Without a published item-level breakdown, the most reliable way to anticipate weak spots is to look at where domain weight and topic complexity intersect. General Code and Construction Knowledge is large and broad - it isn't one topic, it's a collection of code-driven scenarios spanning multiple phases of residential work, which makes it easy to under-scope during study. Carpentry is similarly heavy and technical, covering framing and structural systems that require more than surface familiarity.
On the smaller-weighted domains - Masonry, OSHA Safety, Roofing - the risk isn't complexity, it's neglect. Candidates naturally gravitate toward the big-weight domains during prep and shortchange the smaller ones, not realizing that a poor showing across three or four lower-weighted domains can add up to the same point loss as one bad showing in Carpentry.
- Treating "open book" as a substitute for memorization rather than a backup
- Under-scoping the breadth of General Code and Construction Knowledge
- Skipping targeted review of Masonry, OSHA Safety, or Roofing because they're each under 11% individually
- Preparing for Residential-Basic content while neglecting Business and Law as a separate exam with its own pass/fail line
If you want a compact reference to sanity-check your knowledge before test day, the GARBC Cheat Sheet 2026: One-Page Review of Must-Know Facts condenses the highest-yield facts across all eight domains.
Domain Weight Reference Table
| Domain | Weight | Relative Priority |
|---|---|---|
| General Code and Construction Knowledge | 22.5% | Highest |
| Carpentry | 20% | Very High |
| Associated Trades | 12.5% | High |
| Sitework, Footings and Foundation | 10% | Moderate |
| Concrete and Concrete Reinforcement | 10% | Moderate |
| Roofing | 10% | Moderate |
| OSHA Safety | 8.75% | Moderate-Low |
| Masonry | 6.25% | Lowest (but scored) |
Scheduling Study Time Around Domain Weight
Rather than a generic weekly template, allocate study time proportionally to domain weight, front-loading the two heaviest domains while still leaving dedicated time for every domain before test day. A structure like this respects both the exam's weighting and the reality that Business and Law needs its own separate track.
General Code and Construction Knowledge + Carpentry
- Start with the two heaviest domains (22.5% and 20%) since they carry the most point value
- Build a working vocabulary of code-driven scenarios before moving to memorization drills
Associated Trades + Sitework/Foundation + Concrete
- Cover the mid-weight domains as a block since they share overlapping site-phase context
Roofing, OSHA Safety, Masonry
- Don't skip the smaller domains - combined they're worth more than Carpentry alone
Business and Law + Full Review
- Shift fully to the separate 50-question exam
- Run a full-length timed review of both exams to confirm pacing against the 200-minute and 120-minute limits
Practicing under realistic timing matters as much as content review - you can rehearse both the pacing and the open-book navigation rules using timed sets on our GARBC practice test platform before your actual appointment.
Who's Actually Sitting for This Exam
The Residential-Basic license scope covers detached one- and two-family residences and one-family townhouses up to three stories, plus accessory structures - which shapes who applies. Candidates are typically already working in residential construction, since eligibility requires at least two years of qualifying Residential-Basic experience and demonstrated significant responsibility on two Residential-Basic projects completed in the two years before application. This isn't an entry-level credential; it's a licensing gate for people already doing the work who need the license to legally contract on their own.
Beyond the exam itself, applicants must meet character and financial-responsibility standards, carry at least $300,000 in general-liability insurance, and maintain workers' compensation coverage when required. Once licensed, renewal follows a set cycle by June 30 of even-numbered years, with 3 continuing-education hours required each year and reported through CE Broker. For the complete eligibility picture, see GARBC Requirements 2026: Eligibility, Prerequisites & How to Qualify, and for what the license is worth once earned, Is the GARBC Certification Worth It? Complete ROI Analysis 2026 lays out the tradeoffs.
Understanding who takes this exam also clarifies why pass outcomes vary so much by individual: someone with deep hands-on Carpentry and Sitework experience but limited exposure to formal code language may need to invest disproportionately in General Code and Construction Knowledge, while someone from a code-enforcement or inspection background may need more repetition on hands-on Roofing or Masonry scenarios. Reviewing sample questions on the practice test site before committing to a study schedule can reveal which of these profiles fits you.
Key Takeaway
Your personal "pass rate risk" is really a function of which domains overlap with your existing field experience - identify the gaps early rather than studying every domain equally.
FAQ
No single official pass rate figure is publicly published by the Georgia State Licensing Board or PSI for the Residential-Basic exam. The most reliable planning data is the exam's structure: 70% required on each of the two exams, with domain weighting that shows where points are concentrated.
Yes. The Residential-Basic examination (80 questions, 200 minutes) and the Business and Law examination (50 questions, 120 minutes) are separate tests, each requiring 70% to pass. Passing one does not exempt you from passing the other.
Exam approval is valid for one year and allows three sittings before reapplication rules apply. Use that window to target the specific domains where you fell short rather than re-studying everything equally.
General Code and Construction Knowledge (22.5%) and Carpentry (20%) carry the most combined weight, so they offer the highest return on focused study time - but don't skip the smaller domains, since they add up to a significant share of the score as well.
Both exams are open book under PSI's permanent-tab and no-loose-paper rules, and a silent nonprinting nonprogrammable calculator is permitted. This allows tabbed references but not a loose stack of notes, so you still need strong working knowledge to navigate efficiently under the time limit.
