Plumbing apprenticeships in Oregon are state-registered: under Oregon law, an apprentice plumber must be an apprentice under the state apprenticeship law (ORS 660.002 to 660.210), employed by a licensed plumbing contractor and supervised by a licensed journeyman plumber.
Oregon is a State Apprenticeship Agency state, so programs are registered by a state agency acting for the U.S. Department of Labor.
The union local our research confirmed by name is UA Local 290, and completing a registered 4-year apprenticeship is one of the qualification routes to the Journeyman Plumber license.

Oregon is a State Apprenticeship Agency (SAA) state: registered programs are registered by a state agency acting for the U.S. Department of Labor, not by the federal Office of Apprenticeship.
Required.
Oregon law requires an apprentice plumber to be an apprentice under the state apprenticeship law (ORS 660.002 to 660.210), employed by a licensed plumbing contractor, working under a licensed journeyman plumber's supervision.
UA Local 290 is the Oregon UA local our research confirmed: the UA's find-a-local tool lists it at Portland, and our state research places the local in Tualatin.
JATC details were not verified.
Not established in our research.
No Oregon merit-shop or employer program is named in our sources; ask the PHCC or ABC chapters and check that any program is registered.
Completing a registered 4-year apprenticeship program is one route to the Journeyman Plumber license.
Without an apprenticeship: 576 classroom hours plus 3,850 commercial and 3,850 residential on-the-job hours, or 7,700 commercial plus 7,700 residential hours.
Contact the UA local, Local 290 β or any employer program you find β and ask whether the program is registered with the state.
Federally, a registered apprentice must be at least 16 years old unless a higher minimum age is set by law.
A limited plumbing license: it covers replacing existing water heaters in one- and two-family dwellings.
One of Oregon's limited plumbing specialties, licensed separately from the journeyman license.
One of Oregon's limited plumbing specialties, alongside the water-heater and water-treatment installer licenses.
The license Oregon requires to work as a journeyman plumber, issued under the State Plumbing Board; a certificate of completion from a registered 4-year apprenticeship program is one qualification route.
Oregon is a State Apprenticeship Agency (SAA) state: a state agency there is recognized to act on behalf of the federal U.S. Department of Labor to register and oversee apprenticeship programs in Oregon, rather than registration happening at DOL's Office of Apprenticeship.
Any sponsor of a plumbing apprenticeship in Oregon β a union local, an association chapter or an individual contractor β goes through that state registration.
The union local our research confirmed by name is UA Local 290, the United Association local listed for Oregon.
No employer, association-chapter or community-college plumbing program appeared in our sources by name, so treat any Oregon program we have not named as unverified until you check it.
Whichever program you approach, ask whether it is registered before you sign anything, because Oregon ties apprentice plumbing work to a state-registered apprenticeship.
βRecognized by OA to act on behalf of the federal U.S. DOL to register and oversee programs in their recognized stateβ
Yes β Oregon requires registration, and its statute says so directly.
Under the plumbing statute, an apprentice plumber is an apprentice under the state apprenticeship law (ORS 660.002 to 660.210) who is employed by a licensed plumbing contractor, and an apprentice plumber may work at the trade of plumbing only under the supervision of a licensed journeyman plumber.
Working as a plumbing apprentice in Oregon therefore means being inside a state-registered apprenticeship, employed by a licensed contractor, with a journeyman over you.
The license at the end is a separate credential: Oregon requires a state Journeyman Plumber (JP) license, issued under the State Plumbing Board, to work as a journeyman plumber.
Completing a registered 4-year apprenticeship program (or a training-committee referral) is one qualification route; the others are 576 classroom hours plus 3,850 commercial and 3,850 residential on-the-job hours, or 7,700 commercial plus 7,700 residential hours.
The apprenticeship's own completion certificate β issued by the Registration Agency, Oregon's recognized State Apprenticeship Agency β is not a trade license.
βApprentice plumber means any person who is an apprentice under ORS 660.002 to 660.210 and who is employed by a licensed plumbing contractorβ
The UA local our research confirmed in Oregon is Local 290: the United Association's find-a-local tool lists Local 290 at Portland, and our state research places the local in Tualatin.
Nationally, the UA says its apprenticeships are registered with DOL and typically last five years, covering plumbing, pipefitting, HVACR, welding and fire protection.
Our research did not capture Local 290's intake windows, entrance exams or fees, and it did not verify the local's joint apprenticeship committee (JATC) details, so contact the local directly for application specifics.
For Salem, Bend or other Oregon cities, our research confirmed no program by name; the UA local and the state apprenticeship agency are the places to ask what is registered near you.
βUA apprenticeships typically last five years and cover a range of disciplines.β
Our research confirmed no Oregon merit-shop or employer apprenticeship program by name.
Nationally, PHCC β the Plumbing-Heating-Cooling Contractors Association β offers apprenticeship content through an online learning academy, and ABC (Associated Builders and Contractors) describes itself as founded on the merit shop philosophy and reports more than 24,000 members.
Which chapters of either association, if any, sponsor registered plumbing apprenticeships in Oregon was not verified, and the same goes for individual contractor programs.
If an Oregon employer offers to train you, the test is registration: Oregon law requires an apprentice plumber to be in a state-registered apprenticeship, so ask the sponsor or the state apprenticeship agency whether the program is registered before you sign on.
Our research did not name the Oregon community colleges or training centers that deliver classroom instruction for plumbing apprenticeship programs, so confirm the related-instruction side with your sponsor.
Federally, DOL recommends a minimum of 144 hours of related technical instruction per year of apprenticeship β a recommendation, not a requirement β and whether Oregon adds its own classroom mandate for plumbing apprentices is not established in our research.
Program terms may be time-based, competency-based, or a hybrid of both, so the shape of the classroom and on-the-job hours depends on each program's registered standards.
The classroom hours we did confirm sit on the license side: the 576-hour and 7,700-hour Journeyman Plumber qualification paths named above are what count without an apprenticeship.
Those are license paths, not apprentice-entry rules.
βA minimum of 144 hours for each year of apprenticeship is recommended.β
Pick your route β the UA local, Local 290, or a registered employer or association program if you find one β and ask the program to confirm it is registered: Oregon ties apprentice plumbing work to a state-registered apprenticeship.
Each sponsor sets its own application steps, deadlines and fees; our research did not capture them.
Federally, a registered apprentice must be at least 16 years old unless a higher minimum age is set by law; there is no federal maximum age, and registered programs may not discriminate against applicants 40 or older.
Sponsors can add entry requirements of their own.
If you are accepted, expect pay on a progressively increasing schedule tied to the skill you acquire, a stated apprentice-to-journeyworker ratio in the program standards, a probationary period (if the program has one) no longer than 25 percent of the program length or 1 year (whichever is shorter), and, at completion, a certificate from the Registration Agency β not a license.
From there, the Journeyman Plumber license is the destination: its exam is a 4-hour, 64-question open-book exam, and Oregon BCD licensing exams pass at 75 percent or better, with failed applicants waiting 30 days to retake.
βApprentice means a worker at least 16 years of age, except where a higher minimum age standard is otherwise fixed by lawβ

Not the Journeyman Plumber license.
To work as an apprentice plumber, Oregon's plumbing statute instead requires you to be an apprentice under ORS 660.002 to 660.210, employed by a licensed plumbing contractor, working under a licensed journeyman plumber's supervision β a state-registered apprenticeship, not a license.
You cannot legally work as an apprentice plumber outside that registered system.
Completing a registered 4-year apprenticeship is one route to qualify for the JP license, whose exam is a 4-hour, 64-question open-book exam.
Your program's registered standards fix the term, and our research did not capture Local 290's.
Nationally, the UA says its registered apprenticeships typically last five years, and an apprenticeable occupation must require at least 2,000 hours of on-the-job learning under the industry standard.
Completing a registered 4-year apprenticeship program is one of Oregon's Journeyman Plumber qualification routes, so ask the sponsor for its current term before you apply.
No. Completing a registered apprenticeship earns a completion certificate issued by the Registration Agency β in Oregon, the recognized State Apprenticeship Agency β and a certificate is not a trade license.
But it counts: a certificate of completion from a registered 4-year apprenticeship program is one qualification route for the Journeyman Plumber license, which Oregon requires under the State Plumbing Board.
The other routes use classroom and on-the-job hour totals instead of an apprenticeship.
Federally, a registered apprentice must be at least 16 years old unless a higher minimum age is set by law.
There is no federal maximum age, and registered programs may not discriminate against applicants 40 or older.
Sponsors can add entry requirements of their own, and our research did not capture Local 290's entry standards, so check with the program before you apply.
UA Local 290 is the Oregon UA local our research confirmed: the UA's find-a-local tool lists it at Portland, and our state research places the local in Tualatin.
Our research did not verify the local's joint apprenticeship committee details, intake windows or fees, so contact the local for current application information, and confirm any program it points you to is registered with the state.
