Entry & progression
Six months at or above Wiper, and an examination. That is the QMED. Approved training can buy back up to half the service, and a school-ship graduate needs none of it at all.
The service
46 CFR 12.503(a): six months of service in a rating at least equal to Wiper or Coal Passer. That is the whole sea service requirement. Six months. Wiper time counts in full, which is why the Wiper endorsement is the sensible way in.
The two ways to shorten it
12.503(b) gives approved training real weight — more than almost anywhere else in Part 12:
- A graduate of a school ship qualifies with no further service. Zero. The programme is the service.
- Other Coast Guard-approved training may substitute for up to one-half of the required service — so three months of the six.
TIP — Half is the ceiling, not the default Approved training substitutes for up to one half. It does not automatically halve the requirement — the amount of credit depends on the course and the approval attached to it. Ask the school what its Coast Guard approval actually buys before you pay for it, and get the answer in writing.
The rest of the gate
| Requirement | Detail |
|---|---|
| Age | At least 18 |
| Medical | Medical certificate |
| Drug test | Required |
| English | Must speak and understand English |
| Examination | Must pass the QMED examination for the rating sought |
Note the age. Sea service counts from 16, but the QMED endorsement is not issued below 18. A mariner who starts wiping at 16 can arrive at his eighteenth birthday with the service already banked and the exam already sat. That is the fastest legitimate route into this department, and it is entirely available to yacht crew.
The examination, and what happens when you fail
Each QMED rating is examined separately. 46 CFR 12.205(c) sets the retest rules, and they are more generous than people expect:
- You may retest at any time — there is no waiting period after a first or second failure.
- After a third failure, you must wait 90 days before testing again.
- All tests must be completed within one year of your approval to test.
WARNING — The one-year clock is the one that catches people Your approval to test does not last forever. Everything — all attempts, all modules — must land inside the year. A mariner who fails twice, goes back to sea for eight months and comes home to a lapsed approval has to start the paperwork again. Book the exam early in the window, not late.
How to actually pass it
The QMED exam is not an intelligence test. It rewards the mariner who has been paying attention below and has done the reading. Work the sample question banks until the wrong answers look wrong. Learn the systems on your own boat properly — the fuel system, the cooling system, the lube oil system, the electrical distribution — because a plant you understand in the metal is a plant you can reason about on paper. And sit the exam for the rating you actually want, not the one somebody told you was easiest.
