Apprentice to journeyman ratio rules by state

The apprentice to journeyman ratio is set by each state, and as of 2026 it runs from 1 to 1 up to 3 to 1. Michigan allows 3 registered apprentices per journeyman or master on a jobsite, Minnesota allows 2 unlicensed per licensed electrician, and Washington allows 1 trainee per certified electrician on journey-level work. Federal prevailing wage jobs add their own rule on top.

01Why the ratio is a manpower number

Your ratio caps how many apprentices you can put on a job, so it caps how big a crew your journeymen can run.

Same 4 journeymen, very different crews depending on the state:

That's the best case. Michigan enforces its ratio jobsite by jobsite, so the math only works if the journeymen and apprentices are on the same sites in the right numbers. A J-man in the gear room on Job A doesn't cover three apprentices on Job B.

If you're deciding whether to add journeymen or apprentices next, the ratio is the first thing to check. More on that choice in who to hire next as your shop grows.

02Ratio rules by state (as of 2026)

Here are the rules we checked against the statute or the board's own rule text. Each state has more detail than fits in a table, so click through before you staff a job.

Other states, including Colorado, Oregon, Massachusetts, Connecticut and Nebraska, have their own supervision rules. We haven't checked those against the rule text yet, so call the board before you staff a job there. In states with no statewide journeyman license, a city, county or your registered program's standards may set the ratio instead.

These rules change. Confirm with the state board before you bid manpower off this table.

03The details that trip contractors up

The headline number is only half the rule. These are the parts that cost shops a citation or a red tag.

Who counts as an apprentice

Each state counts different people. Minnesota counts every unlicensed person doing electrical work, registered or not. Iowa counts apprentices and unclassified persons together. Washington counts every noncertified individual, which includes trainees. A "helper" doing electrical work usually counts against the ratio even if you don't call him an apprentice.

How close the J-man has to be

Washington wants the certified electrician on the same jobsite at least 75% of every working day. Iowa wants the same project location. Arkansas sets how often the supervising electrician has to look at the work: on anything other than a one- to four-family dwelling, a first-year apprentice is observed on a direct and continuous basis, a second-year every 30 minutes to an hour, a third-year every 2 to 3 hours, and a fourth-year before the work is operational, complete or covered.

Supervision that changes by year

Wyoming ties supervision to the apprentice's year: 100% in years 1 and 2, 50% in year 3, 25% in years 4 and 5, and back to 100% in year 6 (Wyoming licensing page). An apprentice who's slow to test loses his slack.

Bigger ratios with strings attached

Washington allows 1 certified electrician to 3 or 4 noncertified people in some specialties, including residential, but only if the certified electrician is on site 100% of the day, directly supervises and instructs, and doesn't do any installation himself (RCW 19.28.161(5)). That's a teaching foreman, not a working one. Price it that way.

04Federal and union ratios on top of state law

On top of the state rule, your registered program and federal prevailing wage rules set their own ratio. The tightest one wins on that job.

• Registered programs. Federal apprenticeship standards require "a numeric ratio of apprentices to journeyworkers consistent with proper supervision, training, safety" (29 CFR 29.5(b)(7)). If your program's ratio and the state's differ, staff to the tighter one. See how to start a registered electrical apprenticeship program.
• Davis-Bacon jobs. Apprentices can be paid less than the journeyman rate only if they're individually registered, and only up to the allowed ratio on the jobsite. Any apprentice over the ratio "must be paid not less than the applicable wage rate on the wage determination for the work actually performed" (29 CFR 5.5(a)(4)). On a job outside the area where your program is registered, the project area's ratio and apprentice wage rates apply; if it has none, your program's do. Details in Davis-Bacon for electrical contractors.
• Union shops. The local's agreement and the JATC's standards set the ratio. Ask the JATC for the current number before you staff a job.

Here's what blowing the Davis-Bacon ratio costs, as an example. Say the wage determination shows $45 for an electrician, your program pays a second-year apprentice 50% of that ($22.50), and you put one apprentice too many on site for a 40-hour week. That apprentice is owed $45 an hour, so you owe $900 in back wages on that one hand for that one week, plus fringe. It adds up fast over a 6-month job.

05When "journeymen" turn out to be apprentices

A ratio only works if your journeymen are really journeymen. One national electrical contractor told us agencies sent them hands with apprentice licenses who "just weren't able to do the normal duties as a journeyman." On a job, that does two things: you lose production, and you lose a supervisor. Four J-men and four apprentices in Washington becomes three J-men and five apprentices, and now you're over the ratio.

Check every card before day one. How to verify an electrician's license in any state walks through the 5-minute lookup.

06Use the ratio to plan the next job

Work the ratio backward from the crew the job needs.

1. Count the crew at peak. Say 14 hands in Minnesota.
2. Divide by the ratio plus one. At 2 to 1, each J-man runs a group of 3. 14 divided by 3 is 4.67, so you need at least 5 licensed hands, with up to 9 unlicensed.
3. Check the sites. If those 14 are split across three jobs, do the math per jobsite.
4. Add the foreman. If he's off the tools, decide whether he counts as a supervising electrician in your state. Ask the board.
5. Start recruiting journeymen first. They're the slower hire and the ratio depends on them.
