Plumbing Apprenticeships in Idaho: Programs, Requirements and How to Apply

Idaho is a federal Office of Apprenticeship (OA) state: there is no recognized state apprenticeship agency, so a plumbing program becomes a registered apprenticeship when the US Department of Labor's Office of Apprenticeship registers it, through its field offices in states without an SAA.

Registered apprenticeship pairs on-the-job learning with related technical instruction, and an apprenticeable occupation must require at least 2,000 hours of on-the-job learning.

On the state side, the Idaho Division of Occupational and Professional Licenses (DOPL), the agency behind the Idaho Plumbing Board, publishes a list of board-approved apprenticeship programs; the plumbing side of that list carries the UA Local 648 and UA Local 296 Plumbers and Pipefitters JATCs and Treasure Valley Community College, and six colleges appear under HVAC and plumbing.

The trade columns in DOPL's PDF were read from its layout, so confirm each program's trade on the list before you apply.

Our research did not compile every registered program in Idaho; DOPL's list and apprenticeship.gov are the places to check.

Two registrations come up in Idaho, and they are different things: the apprenticeship itself is the program-level registration with the federal Office of Apprenticeship, because Idaho has no state apprenticeship agency.

The apprentice-level requirement is the state's: Idaho plumbing apprentices must register with DOPL, and the statute says apprentices shall not perform plumbing work except under the supervision of a journeyman; apprentice is one of the three classifications of competency in Idaho plumbing, alongside journeyman plumber and plumbing contractor, plus specialty classes.

Our research did not confirm the DOPL apprentice registration fee or renewal term for plumbing — ask DOPL before you count on either.

The certificate you are working toward is issued for 3 years, and journeyman and contractor renewals require proof of the board's continuing education; the number of CE hours was not in the rules we read, so confirm it with DOPL.

Completing the registered apprenticeship itself earns a certificate from the registration agency — the federal OA here — and that certificate is a credential, not the plumbing license.

The plumbing side of DOPL's board-approved list carries the UA Local 648 and UA Local 296 Plumbers and Pipefitters JATCs.

One caveat from our research: the trade each program is listed under was read from the PDF's column layout, so confirm on DOPL's list that a JATC's program is the plumbing one before you apply.

Nationally, the UA describes its apprenticeships as registered with DOL, typically five years long, and covering plumbing, pipefitting, HVACR, welding and fire protection — a national description, not a statement of either Idaho JATC's terms.

Our research did not capture either local's intake, wages or application windows, so contact the JATC directly about its program.

No PHCC, ABC or ACCA chapter program in Idaho is named in the sources we read; that is what our research shows, not proof that none exists.

Nationally, ABC describes itself as founded on the merit shop philosophy and reports more than 24,000 members, and PHCC offers apprenticeship content through an online learning academy — chapter-level availability is decided chapter by chapter and was not verified for Idaho.

DOPL's list also names Porter House Inc. under HVAC and plumbing; our research did not capture what kind of sponsor it is or how its program is structured.

The test for any employer program is the same as for a union one: Idaho has no state apprenticeship agency, so a registered program is registered by DOL's Office of Apprenticeship — ask who registered any program before you sign on.

The classroom side has named providers in Idaho.

The colleges DOPL's list puts under HVAC and plumbing are College of Eastern Idaho, College of Southern Idaho, College of Western Idaho, Idaho State University, Lewis-Clark State College and North Idaho College, and Treasure Valley Community College also appears on the plumbing side.

The plumbing rules set the instruction figure themselves: the 8,000-hour journeyman path carries 576 hours of board-approved instruction.

The statute's apprentice-to-exam provision — written in the HVAC chapter — lets HVAC apprentices sit the journeyman exam after completing the required hours and related instruction the board approves in conjunction with the state board for career technical education; our research captured that arrangement only in the HVAC chapter, so ask DOPL what the Plumbing Board requires on the plumbing side.

Federally, DOL recommends a minimum of 144 hours of related technical instruction per year of apprenticeship — a recommendation, not a requirement.

Start from DOPL's board-approved list: the plumbing side carries the UA Local 648 and UA Local 296 JATCs and Treasure Valley Community College (trade columns read from the PDF's layout), plus six colleges under HVAC and plumbing.

Apply with the sponsor; our research did not capture application steps, deadlines or fees, so get them from the sponsor and DOPL.

Federal floors set the rest: a registered apprentice must be at least 16 unless a higher minimum age is set by law, there is no federal maximum age, programs may be time-based, competency-based or hybrid, and probation cannot exceed 25% of the program length or 1 year, whichever is shorter; pay follows a progressively increasing, skill-tied schedule with no federally set percentage steps.

Register with DOPL as an apprentice, as required, and build toward the journeyman certificate: 8,000 apprentice hours plus 576 instruction hours, or 16,000 hours of plumbing experience, plus a passing board exam.

Completion brings the registration agency's certificate, a credential, not the license.
