What is an apprentice ratio in construction?

An apprentice ratio is the maximum number of apprentices allowed per journeyworker in a craft. On prevailing wage jobs, apprentices over the ratio must be paid the full journeyworker rate.

An apprentice ratio sets how many apprentices may work for each fully trained journeyworker in the same craft. Registered apprenticeship programs write a ratio into their standards, such as one apprentice to one journeyworker, or one to three. The ratio exists so apprentices get real supervision and so contractors cannot staff a job with cheap labor under an apprentice title.

On most private jobs the ratio is an apprenticeship program rule. On federal and federally assisted jobs covered by the Davis-Bacon Act, it becomes a payroll rule with money attached.

How the apprentice ratio works on Davis-Bacon jobs

The Department of Labor's contract clauses at 29 CFR 5.5(a)(4) let a contractor pay an apprentice less than the wage determination rate only when the apprentice is individually registered in a program registered with the DOL Office of Apprenticeship or a State Apprenticeship Agency recognized by it. The key points:

  • The ratio is per craft on the job site. The allowable ratio of apprentices to journeyworkers in any craft classification on the job site cannot exceed the ratio in the registered program.
  • Over the ratio means full rate. Any apprentice working on the job site beyond the permitted ratio must be paid at least the wage determination rate for the work actually performed.
  • Not registered means full rate. A worker listed at an apprentice rate who is not registered must be paid the wage determination rate for the classification of work performed.
  • Probationary workers. A person certified as eligible for probationary employment can be paid as an apprentice only during the first 90 days.
  • Out of state work. When the job is in a different locality from where the program is registered, the ratio and wage rates of the project's locality apply. If none exist there, the contractor's own program ratio and rates apply.
  • Fringes. Apprentices receive fringe benefits as the program specifies. If the program is silent, they get the full fringe on the wage determination unless the Administrator decides otherwise.

Worked example

Say an electrical sub on a federally funded clinic runs a crew under a registered program with a ratio of one apprentice per journeyworker. On Tuesday the crew is three journeyworkers and five apprentices. Only three apprentices can be paid at their apprentice percentage. The other two must be paid the full electrician rate on the wage determination for the hours they worked that day.

If the journeyworker rate is $48.00 plus fringes, and the over-ratio apprentices were being paid $28.80 (a made-up 60 percent step), each of those two apprentices is owed $19.20 more per hour in base wage, plus any fringe difference. Over an 8 hour day that is $307.20 in back wages just for Tuesday. Over a month it adds up quickly and shows up in a DOL review of the certified payroll.

Common mistakes

  1. Counting the ratio company-wide instead of per craft on the job site.
  2. Using an apprentice whose registration has lapsed or who is registered in a different trade than the work performed.
  3. Moving an apprentice to a job in another state without checking that locality's ratio.
  4. Listing helpers or trainees as apprentices on the WH-347 when no registered program covers them.
  5. Forgetting to keep the apprenticeship registration paperwork with the payroll records.

Related terms

Apprentice ratios connect to prevailing wage, journeyman classifications, fringe benefits, and the WH-347 form. State prevailing wage laws often have their own apprentice rules; see the prevailing wage by state guides and apprentice rules on prevailing wage projects.

Frequently asked questions

What happens if I exceed the apprentice ratio on a Davis-Bacon job?

Under 29 CFR 5.5(a)(4), apprentices working beyond the allowed ratio must be paid at least the wage determination rate for the work they actually performed. Underpayments can be found in a DOL investigation and result in back wages.

Is the ratio based on the whole company or the job?

For Davis-Bacon purposes, the regulation applies the ratio to apprentices and journeyworkers in each craft classification on the job site.

Can an unregistered trainee be paid an apprentice rate?

Not as an apprentice. Only workers individually registered in a program recognized by the DOL Office of Apprenticeship or a recognized State Apprenticeship Agency can be paid below the wage determination rate as apprentices.

Do state prevailing wage laws use the same ratio rules?

Not always. Many states set their own apprentice rules for state public works. Check the state labor agency for your project.
