Alaska Plumbing Apprenticeship

You Can't Just Start Working

This is where most aspiring plumbers in Alaska get tripped up. You find a plumbing company willing to hire you, you show up to the job site, you start learning the trade — and months later you discover that none of those hours count toward your journeyman license because you never registered properly.

Since October 1, 2003, every plumbing trainee in Alaska must be enrolled in a registered apprenticeship program accredited by the U.S. Department of Labor (USDOL) Office of Apprenticeship before a single qualifying hour can accrue. The state does not retroactively credit unregistered work.

The Registration Sequence

1. Find a sponsor. You need a licensed mechanical contractor willing to employ you and sponsor your apprenticeship. This can be a private company or a union training program — UA Local 367 in Anchorage and Local 375 in Fairbanks both run JATC apprenticeship programs.

2. Register with USDOL. Your employer registers you through the federal RAPIDS (Registered Apprenticeship Partners Information Data System). Once registered, you'll get a Davis-Bacon registration letter — this letter is required for the next step.

3. Apply for a Trainee Certificate of Fitness. Submit the COF application to the DOLWD Mechanical Inspection Section along with your Davis-Bacon letter. The filing fees are $50 (application) plus $200 (licensing). Processing takes approximately 7–10 business days.

4. Start accumulating hours — legally. Once your Trainee COF is issued, your on-the-job hours start counting. Not before.

Supervision Rules Are Strict

Alaska enforces a 2:1 trainee-to-journeyman ratio on every job site. No more than two trainees can work under one certified journeyman plumber at any time. State inspectors audit job sites for this, and violations trigger citations, stop-work orders, and fines against the contracting company.

As a trainee, you must work under the direct, in-person supervision of a journeyman. "Direct" means the journeyman is physically present on the same job site — not across town, not available by phone. If the journeyman leaves the site and you keep working, those hours don't count and the employer is in violation.

Tracking Your Hours

The DOLWD recommends that your employer complete an official Experience Verification Form (EVF) every six months or immediately when your employment ends. This is the single most important administrative habit in your apprenticeship.

Here's why: if your employer goes out of business, gets bought out, or simply becomes uncooperative, unsigned hours are effectively lost. The state won't accept your personal time logs. You need that employer signature on the EVF. If you let three years of work go undocumented and the company closes, you're starting over.

Only code-regulated installation work counts toward your 8,000-hour journeyman requirement. The following are explicitly excluded:

• Routine maintenance and repairs
• Janitorial or cleanup work
• Clerical and administrative tasks
• Material delivery and warehousing

What Happens If You Leave the Program

If you leave your registered apprenticeship — quit, get fired, or your employer closes — you must surrender your Trainee COF. Your documented hours stay on file with DOLWD, but you can't work in the trade until you find a new sponsor and re-register.

This is another reason to keep your EVFs current. When you move to a new employer, your documented hours transfer with you. Undocumented hours don't.

The Path Forward

Completing 8,000 hours of documented, supervised apprenticeship work (or 12,000 hours outside a formal program) qualifies you to sit for the journeyman exam. Up to 1,000 hours of accredited classroom training can substitute for field hours, and military plumbing MOS service credits are accepted at 500 hours per year, capped at 4,000 hours.
