Understanding different hiring levels

The levels are separated by what the state allows a person to do unsupervised, not by how good they are. Hiring the wrong level is the most common and most expensive mistake on a trade requisition.

ACheapest to hireApprentice / helper

Productive under supervision and cheap, but they cannot be left on a task the state licenses, and they need someone qualified with them.

What they'll actually be doing
  • ✓Material handling and site preparation
  • ✓Assist a qualified hand on installation
  • ✓Housekeeping and tool staging
What they can't do yet — legally
  • ✕Cannot work unsupervised on licensed work
  • ✕Cannot sign off their own work at inspection
What they need to hold
OSHA 10Apprentice registration where the state requires it
Worth doing
Paying for their certifications is the cheapest retention mechanism you have — the card raises their rate with you rather than with the next employer.
Where recruiters stall
Hiring at this level to save money and then needing licensed work signed off is what blows the schedule.
Only hire when
Use them where a qualified hand is already on site and the work is supervised.
JWhat most requisitions needJourneyman / qualified

Works unsupervised and can carry a helper. This is the level almost every requisition is actually describing.

What they'll actually be doing
  • ✓Runs work without supervision
  • ✓Builds from drawings
  • ✓Carries one to three helpers
  • ✓Handles inspection on their own work
What they can't do yet — legally
  • ✕Usually cannot pull permits in their own name
  • ✕Cannot act as the licence-holder of record
What they need to hold
Journeyman card where the state issues oneOSHA 30Current trade-specific safety training
Worth doing
Ask what they ran on their own and who supervised it. The answer separates a journeyman from a long-serving helper faster than any certificate.
Where recruiters stall
Employers accept "in progress" as though it were held. It is not — and on a licensed scope it stops the job.
Only hire when
Hire here for anything that has to proceed without a supervisor standing over it.
MFor scope and sign-offMaster / lead

Runs crews across sites, owns compliance outcomes, and where the trade allows, pulls permits and qualifies the work.

What they'll actually be doing
  • ✓Runs crews across more than one site
  • ✓Owns compliance and inspection outcomes
  • ✓Estimates and scopes packages
What they can't do yet — legally
  • ✕Cannot trade as a business without a contractor licence, insurance and usually a bond
What they need to hold
Master or supervisor card where the state issues oneContinuing education current
Worth doing
Local permit experience is worth more than generic years. Ask which jurisdictions they have pulled in.
Where recruiters stall
Paying master rates for work a journeyman could run is the other half of the level mistake.
Only hire when
Hire here when the scope needs sign-off, sequencing or several crews.

Screen them properly

Certificates get a candidate past the first filter. These are the questions that separate the ones who can do the work from the ones who have the paperwork, and they change by level.

Interview questions that actually filter

01What did you do on your last site, task by task?
Why it matters: A specific answer tells you what they have actually held in their hands. A vague one usually means they watched.
02Who signed your hours, and can we call them?
Why it matters: Undocumented hours are the single most common problem at this level, and it is the employer who discovers it later.
03Which tools do you own?
Why it matters: It is a proxy for commitment to the trade, and it tells you what you will be supplying on day one.

Rates by sector

01 / 03$26.18/hr

+ Public construction projects
+ Structured departmental teams

Other Specialty Trade Contractors

+ Varied support assignments
+ Practical trade exposure
– Changing project assignments
– Uneven contract workloads
03 / 03$19.94/hr

Nonresidential Building Construction

Recruit for the commercial support tasks. Assess materials handling and instruction-following; budget supervision, onboarding, payroll, benefits, and scheduling beyond wages.

+ Large building projects
+ Coordinated construction crews
– Restricted site access
– Changing project schedules

Questions employers ask

Must helper postings include pay scales?▾
Yes, if you have fifteen or more employees. Labor Code Section 432.3 requires the pay scale in postings, including authorized third-party postings, and the Labor Commissioner's Office enforces it. Applicants can request it from smaller employers.
Can we pay helpers apprentice rates on public works?▾
No, unless they are registered apprentices. The Labor Commissioner's Public Works Manual says a worker must be enrolled in a DAS-approved program to receive apprentice rates; otherwise those craft hours are paid at the journeyman rate.
How do we train multilingual helpers?▾
Cal/OSHA's Title 8 Section 3203 requires safety communication in a form all affected employees readily understand. Train helpers in a language they know and verify understanding before assigning new tasks.
