Why MS-RB Doesn't Use Traditional "Testing Windows"
If you're searching for a calendar of fixed 2026 testing windows for the Mississippi Residential Builder License Exam, you can stop looking for one. Unlike academic certification exams that open and close testing periods a few times a year, the MS-RB trade examination administered through PSI Services LLC on behalf of the Mississippi State Board of Contractors (MSBOC) is available on a rolling, appointment-based basis once you're approved to test. There is no "spring window" or "fall window" - your personal deadline is dictated by your application approval date and the eligibility period that follows it.
This matters because candidates often waste weeks hunting for a registration deadline that doesn't exist, instead of focusing on the deadline that does: the date your MSBOC eligibility expires. Understanding this distinction is the single most important scheduling fact covered in this guide.
The Real Deadline: Your Six-Month Eligibility Window
Once your application is approved and PSI confirms your eligibility, you have six months to schedule and sit for the trade exam. During that window, retakes are unlimited as long as you pay the applicable fee each time - there's no cap on attempts, only a cap on time. If the six-month window lapses without a passing score, your eligibility expires and you must reapply to MSBOC to reset the clock.
This structure changes how you should think about "exam dates." Rather than circling a date on a calendar because it's the only option available, you're choosing your own test date within a six-month runway. That flexibility is useful, but it also means procrastination has real consequences - waiting until month five to schedule your first attempt leaves little room for a retake if you fall short of the 56-correct-answer passing threshold. For a full breakdown of exactly what that passing score means in practice, see MS-RB Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Treat your six-month eligibility period like a countdown clock, not an open-ended deadline. Schedule your first attempt early enough to leave room for at least one retake if needed.
Application-to-Test-Date Timeline
Before any exam date matters, you need to clear the MSBOC application stage. The residential application process is not instantaneous - it requires documentation and verification, so building in lead time before your target test date is essential. Requirements include:
- A qualifying owner, officer, or responsible managing employee named on the application
- At least three completed-job examples demonstrating relevant residential building experience
- Three reference letters - one bank reference and two construction-related references
- Proof of general-liability insurance
- Applicable business and tax registrations
- Workers' compensation coverage if you employ five or more people
The residential application fee is $50 for one classification. Only after MSBOC processes this paperwork and PSI confirms eligibility can you actually book a seat. For a deeper look at each requirement and how to gather documentation efficiently, see MS-RB Requirements 2026: Eligibility, Prerequisites & How to Qualify.
Scheduling With PSI Services
Once PSI confirms your eligibility, scheduling functions like most computer-delivered trade licensing exams: you pick an available seat at a PSI test center based on current openings, not a fixed national test day. The trade exam itself is delivered as a computer-based, open-book format consisting of 80 scored questions to be completed in three hours.
One scheduling nuance worth knowing about: PSI's April 23, 2026 bulletin notes that the exam may include between one and ten additional unscored experimental questions mixed in with the scored content. These pretest items count against your total exam time even though they don't count toward your score, so budget your three hours as if every question matters - because from a time-management standpoint, it does.
Because the exam is open-book, part of your "scheduling" prep also includes organizing your references before test day. Approved reference categories include:
- The 2021 International Residential Code
- OSHA 29 CFR 1926
- Concrete references
- Masonry references
- Carpentry references
- BCSI truss bracing guidance
- Pipe and excavation references
- Roofing references
Use the specific code edition listed - older or newer non-code references are used at your own risk if content has changed. You're permitted to bring highlighted, underlined, and permanently tabbed materials, but handwritten notes, loose papers, and temporary tabs are not allowed at the testing station. A silent, nonprinting, nonprogrammable calculator is also permitted.
Key Takeaway
Schedule your exam date only after your reference books are tabbed and organized - reorganizing an open-book reference system the night before is a common, avoidable time-waster.
Fees Tied to Every Attempt
Every scheduled date carries a cost, and those costs stack depending on how many exam portions you still need to pass. The trade exam fee is $120 per attempt, including retakes - there's no discount for repeat sittings. Because the Law and Business Management exam is a separate, required component, trade plus business-law fees together total $240.
Add the $50 residential application fee, and the full cost of application plus both exam portions comes to $290 before books, prep materials, insurance, or other incidental expenses. This is worth mapping out before you schedule your first date, since a failed attempt on either exam means paying that portion's fee again for your next scheduled sitting.
| Item | Cost | Notes |
|---|---|---|
| Residential application | $50 | One classification |
| Trade exam (per attempt) | $120 | Includes retakes |
| Law and Business Management exam | Included in $240 combined total | Separate required exam |
| Application + both exam portions | $290 | Before books, prep, insurance |

Planning Your Prep Around the Nine Domains
Because you control your own test date within the six-month eligibility window, you also control how much runway you give yourself to study. The exam's nine domains carry different question weights, and PSI's official 80-question allocation makes some domains far more consequential than others.
Domain 7: Estimating, Plan Reading and General Code Requirements
This is the largest domain on the exam at 18 questions, covering plan interpretation, code-based estimating logic, and general residential code application.
- Prioritize this domain first when building your study schedule since it carries the most weight
Domain 4: Carpentry
Carpentry accounts for 15 questions, making it the second-largest content area on the trade exam.
- Review framing, structural carpentry, and related IRC provisions closely
Domain 1: Site work, Footings and Foundations
With 13 questions, this domain rounds out the three largest content areas and deserves proportional study time.
- Pair this domain's review with your concrete and masonry study sessions since the topics overlap in practice
The remaining domains - Concrete and Concrete Reinforcement, Masonry, Associated Trades and Drywall, Roofing, OSHA Safety, and Licensing - round out the 80-question exam and shouldn't be neglected, even though they carry fewer questions individually. For the complete question-count breakdown across all nine domains and how to weight your study time accordingly, see MS-RB Exam Domains 2026: Complete Guide to All 9 Content Areas.
Estimating, Plan Reading and General Code Requirements + Carpentry
- Work through IRC-based estimating and plan-reading scenarios
- Review framing and structural carpentry provisions
Site work, Foundations, Concrete, and Masonry
- Study footing and foundation requirements alongside concrete reinforcement basics
- Cross-reference masonry sections of your approved references
Roofing, Associated Trades/Drywall, OSHA Safety, Licensing
- Cover the smaller domains and reinforce OSHA 29 CFR 1926 fundamentals
- Review MSBOC licensing rules that appear on the Licensing domain

Retake Timing and Reapplication
Because retakes are unlimited within your six-month eligibility window, a scheduling failure isn't the end of the road - but it does cost another $120 per trade-exam attempt. If your eligibility period expires before you pass, you'll need to submit a new application to MSBOC and restart the eligibility clock, so it's worth scheduling retakes promptly rather than letting momentum stall.
One important note for candidates coming from another state: reciprocity-based waivers for the trade exam do not waive the Law and Business Management exam. Even if your trade-exam requirement is waived through reciprocity, you'll still need to schedule and pass the business-law portion separately.
After You Pass: Renewal Dates and CE Deadlines
Passing your scheduled exam date is a milestone, not the finish line. Mississippi residential licenses renew annually for $100, or $110 if you renew late within the permitted grace period. If your license lapses more than 180 days, you can't simply renew late - you'll need to submit an entirely new application, which brings you back through the same scheduling and fee process described above.
For active residential qualifiers holding licenses issued on or after July 1, 2015, there's an added annual deadline: two approved continuing education hours each year. Inactive status is exempt from this CE requirement, but if you're actively working under the license, missing this deadline can affect your renewal standing.
Understanding these post-exam dates matters just as much as your original test-date planning, since a missed renewal or CE deadline can put you back in a position of dealing with MSBOC paperwork instead of running your business. If you're evaluating whether the entire licensing path - exam dates, fees, and ongoing CE - is worth the investment for your career plans, Is the MS-RB Certification Worth It?

Key Takeaway
Mark your renewal date and CE deadline on the same calendar where you tracked your original six-month exam eligibility window - the licensing process doesn't stop once you pass.

FAQ
No. The Mississippi Residential Builder trade exam is scheduled on an ongoing basis through PSI Services LLC once MSBOC approves your application and confirms eligibility, rather than through fixed quarterly or annual testing windows.
You have six months of eligibility to schedule and sit for the exam, with unlimited retakes permitted during that window as long as each attempt's fee is paid.
You'll need to reapply to MSBOC to establish new eligibility, which restarts the application process and fees before you can schedule another PSI test date.
Build in enough lead time to gather your three completed-job examples, three reference letters, insurance documentation, and business registrations before submitting your MSBOC application, since these steps typically take longer than the PSI scheduling step itself.
No. You must also pass the separate Law and Business Management exam, and reciprocity-based waivers for the trade exam do not waive that business-law requirement.
