- The PSI examination fee for CT-P2 is $59 per attempt, separate from Connecticut DCP fees.
- DCP charges a $90 application fee before PSI scheduling is even possible.
- Annual license renewal costs $120, due before the October 31 expiration each year.
- Eligibility is valid for one year with unlimited exam attempts, so retakes only cost the $59 PSI fee.
CT-P2 Total Cost Overview
Anyone researching the Connecticut P-2 Unlimited Journeyperson Plumber license wants one thing first: a real number. Unlike marketing materials for other credentials, the CT-P2 pathway is administered jointly by the Connecticut Department of Consumer Protection (DCP) and Plumbing and Piping Work Examining Board, with PSI Services LLC handling the computer-based examination itself. That split means your total cost is really two separate ledgers - what DCP charges for licensing paperwork, and what PSI charges to sit for the exam.
At minimum, a candidate moving through the process once, passing on the first attempt, and renewing annually will pay the $90 DCP application fee, the $59 PSI examination fee, and the $120 annual renewal fee once the license is issued. That is the baseline. Retakes, reference materials, and continuing education add variable costs on top, which we break down below.
DCP Application Fee
Before you can schedule anything with PSI, the Department of Consumer Protection requires a $90 application fee tied to your journeyperson application. This step confirms your eligibility documentation - typically an approved apprenticeship record, or for candidates using the equivalency pathway, proof of 8,000 on-the-job hours and 576 classroom hours. DCP reviews and approves this eligibility before PSI opens a scheduling window for you.
This $90 fee is a one-time cost per approved eligibility period, not something you pay every time you sit for the exam. If you need the full picture of what DCP checks during this review, the CT-P2 Requirements 2026: Eligibility, Prerequisites & How to Qualify guide walks through documentation expectations in detail.
Key Takeaway
Budget the $90 DCP fee as a separate line item that comes before you ever see a PSI invoice - it's the gatekeeping step for the entire process.
PSI Exam Fee and Retake Costs
Once DCP approves your eligibility, PSI charges $59 per examination attempt. The CT-P2 exam itself is a computer-based, open-book test consisting of 70 scored questions in 150 minutes, with up to 10 additional unscored questions mixed into the same time block (you won't know which questions are unscored, so every item deserves full attention). A passing score is 70%, or 49 of the 70 scored questions correct.
Here's the financially important detail: DCP eligibility lasts one full year, and during that year you get unlimited examination attempts. That means if you don't pass on your first try, a retake costs only the $59 PSI fee again - you don't need to reapply to DCP or pay the $90 fee a second time, as long as you're still inside your one-year eligibility window.
This structure rewards preparation. Someone who studies the exact 16 content domains thoroughly and passes on attempt one spends $59 on testing. Someone who needs two or three attempts within the same eligibility year spends $118 or $177 on PSI fees alone.

Reference Book Investment
The CT-P2 exam is open-book, but that doesn't mean cost-free preparation. PSI's bulletin specifies exactly which references you're permitted to bring into the testing room, and candidates are responsible for sourcing their own approved copies:
- International Plumbing Code - 2015, 2018, or 2021 edition
- NFPA 54 National Fuel Gas Code or Handbook, 2012
- NFPA 58 Liquefied Petroleum Gas Code, 2014
- OSHA 29 CFR 1926, with latest amendments, or PSI's listed selections
- Water Processing: Residential, Commercial, Light Industrial, third edition, 2000
- NFPA 56, PSI's listed current edition
Two other titles - Mathematics for Plumbers and Pipefitters and Plumbing Design and Installation - are useful for study purposes but are not permitted inside the exam room. Treat them as prep-only investments, not testing-day tools.
PSI allows prior highlighting, underlining, annotation, and permanent tabs in your approved books, but prohibits question-and-answer notes, loose or attached papers, temporary tabs, and any writing during the exam itself. A silent, nonprinting, nonprogrammable calculator is also allowed. Practically, this means your book cost is a one-time purchase you can annotate heavily in advance and reuse for retakes - there's no reason to buy fresh copies for a second attempt.
Where Your Book Budget Matters Most
Drain, Waste, and Vent is the largest domain on the 70-item outline at 11 questions, so your IPC copy should be the most heavily tabbed and annotated reference you own.
- Prioritize IPC tabs for DWV sizing and venting sections
- Mark NFPA 54 sections relevant to the Gas Systems domain
- Flag Water Processing chapters tied to the Water Treatment domain

Annual Renewal Costs
Passing the exam and receiving your P-2 Unlimited Journeyperson Plumber license isn't the end of the cost conversation. Connecticut licenses expire annually on October 31, and renewal requires a $120 fee paid to DCP. This is a recurring cost for as long as you hold the license, separate from the one-time application and exam fees paid during initial licensure.
Because P-2 holders work only as employees of properly licensed contractors, this renewal fee is typically a straightforward line item in your annual professional expenses - no business licensing or contractor-level fees apply at the P-2 level, since that would fall under a separate P-1 contractor classification with its own Business and Law examination requirement that P-2 candidates do not need to take.
Key Takeaway
Mark October 31 on your calendar every year. The $120 renewal fee is due before expiration, and letting it lapse creates avoidable administrative headaches.
Continuing Education Costs
Connecticut requires journeypersons to complete five approved continuing education (CE) credit hours every two years, with the deadline set at July 31 of odd-numbered years. Notably, your first renewal cycle after initial licensure is exempt from this CE requirement, giving newly licensed P-2 holders one renewal period before CE costs enter the picture.
CE course pricing varies by provider, so rather than quote a number that isn't part of the official fee schedule, budget CE as a recurring biennial cost alongside your renewal fee starting with your second renewal cycle. Planning for it in the same calendar block as your $120 renewal payment keeps your annual licensing budget predictable.
Cost Breakdown Table
| Cost Item | Amount | Frequency |
|---|---|---|
| DCP Application Fee | $90 | One-time, before PSI scheduling |
| PSI Examination Fee | $59 | Per attempt |
| Annual License Renewal | $120 | Every year by October 31 |
| Continuing Education | Varies by provider | 5 hours every 2 years (first renewal exempt) |
| Reference Materials | Varies by title/edition | One-time (reusable for retakes) |
This table intentionally excludes any figures that aren't part of the official DCP or PSI fee schedule. If a study resource quotes you a "certification fee" that doesn't match these numbers, double-check that it's describing the Connecticut P-2 process and not a different credential entirely.
Overlooked Costs and Eligibility Routes
The biggest hidden "cost" of the CT-P2 process isn't a fee at all - it's time invested in meeting eligibility before you ever touch the $90 application. Candidates who go through an approved apprenticeship generally have their hours and classroom training already documented. Candidates using the equivalency route, however, must independently document 8,000 on-the-job hours and 576 classroom hours before DCP will approve eligibility.
Gathering that documentation - employer letters, training certificates, hour logs - can take weeks if records are scattered across multiple employers or training providers. That's not a dollar cost, but it is a real timeline cost that delays your $90 application and, by extension, your entire path to the $59 PSI exam. Start compiling equivalency documentation as early as possible if you're not coming through a traditional apprenticeship.
Minimizing Your Total Investment
The single most effective way to reduce your total CT-P2 cost is straightforward: pass on the first attempt and avoid paying the $59 PSI fee more than once. That means allocating your limited study weeks toward the domains that carry the most questions and the topics most likely to trip up unprepared candidates.
High-Weight Domains
- Drain, Waste, and Vent (11 questions) - the single largest domain
- Water Supply and Piping, Valves, Controls fundamentals
Calculation-Heavy Domains
- Isometric Analysis and Developed Length (nine questions combined)
- Gas Systems sizing and code references in NFPA 54
Remaining Domains and Book Familiarity
- Backflow, Traps and Interceptors, Water Treatment, Safety and Excavation
- Practice locating answers quickly in your tabbed reference books
This isn't generic advice about study techniques - it's a sequence built around PSI's actual 70-item outline, where Drain, Waste, and Vent alone outweighs several smaller domains combined. For a full week-by-week study plan and guidance on managing the open-book format under time pressure, see the CT-P2 Study Guide 2026: How to Pass on Your First Attempt. And if you want to confirm exactly what score you're aiming for before test day, the CT-P2 Passing Score 2026: Exactly What You Need to Pass article breaks down the 49-of-70 threshold in more detail.
You can also reinforce domain-specific weak spots using timed practice questions on our CT-P2 practice test platform before committing to a PSI testing date - a cheaper way to gauge readiness than paying for a retake attempt.
Frequently Asked Questions
Assuming a single passing attempt, expect the $90 DCP application fee plus the $59 PSI examination fee before licensure, followed by the $120 annual renewal fee once licensed. Reference materials and eventual continuing education add variable costs on top.
No. Eligibility lasts one year and allows unlimited examination attempts during that window. A retake only requires paying the $59 PSI fee again, not the $90 DCP application fee.
No. The P-2 Unlimited Journeyperson Plumber classification requires only the trade examination. The Business and Law examination applies to the separate P-1 contractor classification, not P-2.
Not right away. Your first renewal cycle after initial licensure is exempt from the five-hour CE requirement. Budget for CE starting with your second renewal, due by July 31 of an odd-numbered year.
Yes. PSI permits prior highlighting, underlining, annotation, and permanent tabs in your approved books, so a well-marked copy of the IPC or NFPA codes can be reused for any retake within your eligibility year.
