The Prov Transition: What Changes in 2026
If you've researched the Tennessee Full Mechanical Contractor (CMC) exam before, you may have run into outdated scheduling instructions tied to PSI. That's changing. Prov takes over new TN-CMC exam scheduling beginning July 1, 2026. If you already booked an appointment through PSI before that date, don't panic - those already-scheduled PSI appointments remain valid and are honored through September 2026.
This matters for anyone planning around specific 2026 windows: if your license timeline depends on sitting for the exam in the second half of the year, you'll want to know which system you're actually scheduling through and confirm the current bulletin rather than relying on legacy PSI instructions that no longer apply.
How to Register and Schedule Your Exam
Scheduling the TN-CMC exam isn't a single click-and-go process - it's the last step in a sequence that starts with the Tennessee Board for Licensing Contractors. Before Prov will let you pick a date, the Board has to sign off on your eligibility for the full CMC classification, which covers both plumbing and HVAC scopes.
- Submit your plumbing-experience documentation to the Board for preapproval (see the deadline discussion below).
- Once approved, use your Board authorization to create a candidate profile and book a seat through Prov's scheduling portal.
- Choose a physical test center or Examroom.ai remote-proctoring session, depending on availability and your preference.
- Pay the per-attempt exam fee and confirm your appointment window.
Because approval has to happen before scheduling, candidates who wait until the last minute to submit paperwork often lose their ideal testing date. Build in buffer time - the Board's review isn't instantaneous, and neither is Prov's confirmation cycle.
Fees Tied to Every Scheduling Step
Scheduling isn't just about picking a date - it's tied to a specific sequence of payments. Knowing what's due when helps you budget and avoid a surprise hold on your appointment.
| Fee | Amount | When It's Paid |
|---|---|---|
| Board CMC preapproval fee | $50 | Before scheduling is possible |
| Prov examination fee | $53 per attempt | At scheduling, and again for any retake |
| Initial contractor-license fee | $250 | After passing, during licensure |
| Biennial renewal fee | $200 | Every two years post-licensure |
For a full breakdown of how these figures stack against total licensing cost, see the detailed walkthrough in TN-CMC Certification Cost 2026: Complete Pricing Breakdown.
Testing Format, Locations, and Remote Proctoring
The TN-CMC exam is computer-delivered and open-book, which changes how you should plan your scheduling around study time. You're not trying to memorize every code section cold - you're trying to know exactly where to find the right answer fast, under time pressure, in the approved references.
Prov gives candidates two scheduling paths:
- In-person test centers - traditional proctored testing at a Prov-affiliated location.
- Examroom.ai remote proctoring - sit for the exam from a compliant location of your choosing, monitored remotely.
Whichever path you pick, the reference-material rules are the same: advance highlighting and permanent tabs are allowed in your approved books, but handwritten notes, loose papers, and movable tabs are not. A simple four-function calculator is permitted. If you're assembling your open-book kit, plan it around this exact rule set rather than what worked for a different exam - see TN-CMC Study Guide 2026: How to Pass on Your First Attempt for how to prep your references correctly before test day.
Key Takeaway
Tab and highlight your IMC 2021, IFGC 2021, and HVAC Basics for Contractors (4th edition) references weeks before your scheduled date - not the night before. Loose notes get confiscated at check-in.
Board Preapproval: The Deadline Before the Deadline
The real scheduling bottleneck for most candidates isn't Prov's calendar - it's Board preapproval. You must be at least 18 years old and document three years of plumbing experience before the Board will clear you to schedule. The Board's approval form also accepts specified alternative documentation, including qualifying engineering-degree paperwork, for candidates whose path into the trade didn't run through a traditional plumbing apprenticeship.
Your qualifying agent - the person whose experience and exam results back the license - can be an owner, an officer, or a full-time employee of the contracting business. That flexibility matters for scheduling because it means the person sitting for the CMC exam doesn't have to be the same person who eventually handles the separate Tennessee Business and Law exam; those two qualifying-agent roles can be filled by different individuals.
For a complete rundown of what the Board wants to see in your preapproval packet, review TN-CMC Requirements 2026: Eligibility, Prerequisites & How to Qualify before you start gathering documentation - not after you've already tried to book a date and been turned away.
Scheduling Around the 13 Domains
The June 15, 2026 Prov CMC outline confirms the exam draws from 100 questions across 13 domains, and the weighting is far from even. Knowing this breakdown should directly shape when you schedule your exam relative to how much study time you have left.
| Domain | Questions |
|---|---|
| 1. General Knowledge | 6 |
| 2. Code Requirements | 5 |
| 3. Fuel Gas Systems | 8 |
| 4. Safety | 8 |
| 5. Controls | 4 |
| 6. Electrical Concepts | 4 |
| 7. Piping | 8 |
| 8. Load Calculations | 5 |
| 9. Equipment | 10 |
| 10. Refrigerants and Oils | 10 |
| 11. Air Distribution and Vents | 18 |
| 12. Fire Protection | 4 |
| 13. Sprinkler Systems | 10 |
Air Distribution and Vents (Domain 11)
At 18 questions, this is the single largest domain on the blueprint - nearly a fifth of the exam. Candidates scheduling their test date should not book a session until they're confident navigating ductwork sizing, venting requirements, and distribution-system code references without hesitation.
- Cross-reference IMC 2021 sections on air distribution before locking your test date
- Practice locating vent-clearance tables quickly in your tabbed reference book
If you don't yet have a firm grip on how all 13 domains interact and where the smaller-weighted domains (Controls, Electrical Concepts, Fire Protection) still deserve attention despite lower question counts, work through TN-CMC Exam Domains 2026: Complete Guide to All 13 Content Areas before you commit to a scheduling date.
A Realistic Scheduling Countdown
Rather than a generic study calendar, here's a scheduling-focused countdown that ties directly to TN-CMC's preapproval-then-booking structure.
Documentation and Preapproval
- Submit plumbing-experience proof (or alternative documentation) to the Board
- Confirm your qualifying-agent status matches the license type you're pursuing
Book Your Prov Appointment
- Choose test center or Examroom.ai remote proctoring
- Pay the $53 Prov exam fee and lock your date
Domain-Weighted Review
- Prioritize Air Distribution and Vents, Equipment, Refrigerants and Oils, and Sprinkler Systems
- Tab your IMC 2021, IFGC 2021, and HVAC Basics for Contractors references
Logistics Check
- Verify your test-center address or remote-proctoring system requirements
- Confirm no loose papers or handwritten notes are packed with your references

Results Validity and the Business & Law Exam
Once you pass, your exam results are typically accepted for two years - plan any remaining licensing steps (financial qualification, insurance, bonding, business documentation) inside that window so your passing score doesn't expire before your license application is complete.
Remember that new contractor applicants also need to pass the separate Tennessee Business and Law examination. Because that exam can be scheduled and passed by a different qualifying agent than the one who sat for the trade exam, larger contracting businesses have flexibility in how they staff their qualifying roles - but solo operators need to plan for sitting both exams within their own timeline.
Also worth noting for your overall project planning: a license is required before bidding or contracting on covered projects of $25,000 or more, and beginning July 1, 2026, the Board permits a contractor surety bond as an alternative to a CPA-reviewed or CPA-audited financial statement - a detail that can simplify your post-exam licensing paperwork if your scheduling puts you on the far side of that date.
