KY-MP Exam Dates 2026: Testing Windows, Deadlines & Scheduling

2026 Exam Calendar and Testing Windows

The Kentucky Department of Housing, Buildings and Construction (DHBC), through its Division of Plumbing, does not run the master plumber exam on demand. The State Plumbing Examining Committee schedules it four times a year, and those months are fixed: February, May, August, and November. If you miss a window, you wait roughly three months for the next one - which is exactly why scheduling mistakes on the KY-MP are more costly than they might seem for other trade licenses.

Because the state publishes a formal exam schedule rather than allowing rolling registration, your entire prep timeline should work backward from the nearest of these four months. If you're still assembling eligibility documentation, treat the next testing window as a hard deadline rather than a target.

Application Deadlines and the PLB-3 Form

DHBC requires a complete examination application at least three weeks before the scheduled exam date. "Complete" is the operative word - an application missing supporting documentation or a required attachment is not considered submitted on time, even if it arrives before the cutoff.

The registration document itself is Form PLB-3, and it has one detail candidates frequently overlook: it requires a recent, passport-sized color photograph. Applicants who mail in a form without the correct photo format, or with a photo that's outdated, risk delays that push them past the three-week threshold entirely.

• Confirm the current testing month before assembling documents - the four annual windows don't shift, but specific dates within them can.
• Attach a recent color passport-style photo directly to the PLB-3 form.
• Submit at least three weeks ahead - earlier is safer given mail processing and any follow-up requests from DHBC.
• Keep a copy of everything submitted, including proof of mailing or delivery confirmation.

Eligibility Timing Before You Register

Scheduling only matters if you're actually eligible to sit for the exam. Kentucky's standard pathway requires candidates to be at least 18 years old, hold a journeyman plumber license for at least two of the preceding five years, and have at least two years of active work experience under a licensed master plumber. These aren't boxes you check the week before applying - they're time-based requirements that should shape when you even start planning your exam date.

If your journeyman tenure or supervised work experience is close to the two-year threshold, calculate the date it's satisfied and choose the next testing window that falls after it, with buffer room. Applying before you technically meet the requirement risks rejection and a lost cycle.

Engineers and out-of-state applicants follow alternative routes defined in 815 KAR 20:030. Notably, the out-of-state pathways still require proof of having passed the Kentucky journeyman examination - an out-of-state master license alone doesn't substitute. If this applies to you, verify your documentation well before the three-week application deadline, since gathering out-of-state records often takes longer than expected.

Fees: What You Pay and When

Each attempt at the Kentucky master plumber exam costs $150. This is a per-attempt fee, meaning candidates who don't pass both portions on a given sitting will pay it again to retest in a future window. Fee accuracy matters for planning - budgeting for a single attempt when you might need two changes how much runway you should give yourself before a licensing goal.

Separately, once you pass, the master license itself carries a base fee of $250, with proration for initial terms of seven to eighteen months, plus a $250 annual renewal due at the end of your birth month. Renewal also requires proof of insurance and six approved continuing education hours completed in the preceding 12 months - though that CE requirement is waived for your very first renewal if the license was issued within the prior 12 months.

What's Actually Tested on Exam Day

Scheduling wisely requires understanding what you're scheduling for. The Kentucky master exam has exactly two official portions, and both must be passed independently - there's no averaging your way to a passing outcome.

Passing requires scoring at least 80% on each portion separately, and the entire exam - both Written and Chart combined - is completed within a total time limit of 2 hours 30 minutes. That's a tight window when one section involves detailed drawing work.

Scheduling Strategy by Domain

Because the KY-MP only runs four times a year, your prep calendar should be built around the specific testing month you're targeting, not a generic countdown. Given that Written and Chart require genuinely different skills - statutory recall versus drawing-based sizing judgment - splitting your final weeks by domain, rather than mixing both every session, tends to produce sharper results.

This structure isn't generic advice repackaged - it's built directly around the fact that Written and Chart are graded as separate 80% thresholds, so weak preparation in either one can sink an otherwise strong attempt.

The One-Year Void Window and Score Validity

Two timing rules matter just as much as the testing calendar itself. First, an examination application becomes void if you don't successfully complete the exam within one year of the first notice of examination. That means if you apply, get scheduled, and then delay or skip that sitting, you can't sit on the same application indefinitely - after twelve months, you're back to square one with a new application.

Second, once you do pass, that passing score remains valid for three years. This matters if you're not planning to immediately submit your master license application - perhaps you're finishing other requirements or timing it with a renewal cycle. Just don't let that three-year clock run out before you act on it.

After You Pass: Licensing Timelines

Passing the exam is not the same as holding a master plumber license. You still need to complete the licensing application process, pay the $250 base fee (prorated for initial terms of seven to eighteen months), and provide proof of insurance. From there, renewal is annual, due at the end of your birth month, and requires six approved continuing education hours completed in the preceding twelve months - except your very first renewal, which is exempt from the CE requirement if your license was issued within the prior year.

Factor these downstream steps into your original exam-date planning. Someone who passes in a February sitting but delays submitting license paperwork for months is leaving earning potential on the table.
