GARBC Passing Score 2026: Exactly What You Need to Pass

The Passing Score, Stated Plainly

If you're preparing for the Georgia Residential-Basic Contractor License Exam (GARBC), the number to remember is 70%. That's the passing score required on both examinations you must clear to become licensed: the 80-question Residential-Basic trade exam and the separate 50-question Business and Law exam. There's no sliding scale, no curve, and no "close enough" - the Georgia State Licensing Board for Residential and Commercial General Contractors, Residential Contractors Division, sets 70% as the threshold on each exam independently, and PSI administers both under that standard.

What trips people up isn't the number itself - it's what 70% actually means in practice once you account for time limits, question format, and the possibility of unscored items mixed into the test. This article breaks down exactly what you need to hit that mark, exam by exam, domain by domain.

Why Two Exams Means Two Passing Scores

A common misconception among first-time applicants is treating "the GARBC exam" as a single test with one combined score. It isn't. You're actually clearing two separate hurdles:

• Residential-Basic Examination: 80 questions, 200-minute limit, covering the eight trade domains that define scope of work for detached one- and two-family residences and one-family townhouses up to three stories, plus accessory structures.
• Business and Law Examination: 50 questions, 120-minute limit, covering the administrative, contractual, and regulatory side of running a licensed contracting business in Georgia.

Each exam requires its own 70% score. Passing one does not carry over to or offset the other. If you're strong on trade knowledge but weak on business and legal topics, you can still fail overall - and vice versa. This is a distinct feature of how Georgia structures residential licensure, and it's why smart candidates study both tracks with equal seriousness rather than assuming the trade exam is the only "real" test. For a full breakdown of what's required before you even sit for either exam, see the GARBC Requirements guide.

How PSI Scores the Residential-Basic Exam

PSI administers both computer-based exams and applies the 70% threshold to scored questions. One detail candidates frequently overlook: PSI may include unscored experimental questions in the exam. These are items being tested for future use on the exam bank - they look identical to real scored questions, appear mixed in with the rest of the test, and are not disclosed to you during the exam.

Practically, this means you should never try to "count" your way to 70% in your head during the test, assuming a fixed denominator of exactly 80 or 50 questions. You won't know which items are experimental, so the only sound strategy is to treat every single question - trade or business, familiar or unfamiliar - as if it counts, because it might.

How Domain Weighting Affects Your Score

The Residential-Basic exam's 80 questions aren't distributed evenly across topics. They follow a weighted domain structure, and understanding those weights is the single most useful thing you can do to plan your study time efficiently. Here's the breakdown:

Because General Code and Construction Knowledge and Carpentry together account for 42.5% of the exam, weakness in either domain has an outsized effect on whether you clear 70% overall. A candidate who is excellent at Masonry (6.25% of the exam) but shaky on General Code and Construction Knowledge is in a much worse position than the reverse scenario. For a domain-by-domain walkthrough of what each of these eight areas actually tests, the GARBC Exam Domains Guide goes deeper than we can here.

Raw Questions vs. Practical Score Targets

Because 70% is the bar, it helps to think in concrete terms rather than abstract percentages. On the 80-question Residential-Basic exam, a 70% threshold means you need to answer roughly 56 of 80 scored questions correctly - though the exact scored-question count may shift slightly if experimental items are present. On the 50-question Business and Law exam, 70% means roughly 35 of 50 questions correct.

These are approximate framings, not official cutoffs published question-by-question - PSI applies percentage-based scoring, not a fixed "missed question" count that's publicly disclosed. But framing it this way is useful for self-assessment: when you take practice questions on our practice test platform, you can gauge readiness by tracking whether you're consistently clearing that 70% line across full-length practice sets, not just on topics you already know well.

The Open-Book Factor and What It Doesn't Change

Both the Residential-Basic exam and the Business and Law exam are open book, administered under PSI's permanent-tab and no-loose-paper rules. A silent, nonprinting, nonprogrammable calculator is also permitted. This surprises some candidates into thinking the exam is "easier" than a closed-book test - but the 70% passing score doesn't move because reference material is allowed.

Open-book format changes your strategy, not your target. You still need to know where information lives in your permitted references and how to apply it quickly, because the 200-minute and 120-minute time limits don't stretch to accommodate slow lookups. Candidates who over-rely on flipping through tabs during the exam often run out of time before finishing all 80 or 50 questions - and an unanswered question counts against you the same as a wrong one. If you're unsure how the open-book format actually affects difficulty, How Hard Is the GARBC Exam? covers this in more detail.

Building a Score-Focused Study Schedule

Rather than studying every domain equally, allocate your preparation time roughly in proportion to exam weight, with extra buffer time on the two heaviest domains. A simple way to structure this over several weeks:

This is only one possible sequence - the point is proportional allocation, not a rigid formula. For a more complete walkthrough of preparation strategy, including how to structure review sessions and select study material, see the GARBC Study Guide.

If You Miss 70%: Retake Rules to Know

Scoring just under 70% is frustrating, but Georgia's process does account for retakes. Exam approval is valid for one year and allows three sittings before reapplication rules apply. That means if you don't clear 70% on your first attempt, you have additional opportunities within that one-year approval window before you'd need to submit a new application.

This is a meaningful planning detail: don't treat your first attempt as a "trial run" hoping you'll just retake it indefinitely. Three sittings within a one-year approval period is a limited runway, so each attempt should be treated as a serious effort, not a diagnostic exercise. Understanding the full cost structure of retakes and reapplication is also worth reviewing in the GARBC Certification Cost breakdown.

It's also worth understanding, more broadly, how difficult this exam tends to be relative to other paths into residential contracting, and whether the licensure is worth the investment of time and the $300,000 general-liability insurance and workers' compensation requirements that come with it. The GARBC Pass Rate article and the ROI analysis on GARBC certification both address these questions in more depth, and the GARBC Salary Guide looks at earning potential for licensed residential-basic contractors.
