Federal Law (FCRA)
The Fair Credit Reporting Act (FCRA) establishes the federal minimum requirements for employment background checks, including disclosure and authorization requirements, consumer rights, and the adverse action process. Many states impose additional requirements that employers must also follow.
Read FCRA OverviewRecommended Screening Components
The components below reflect common elements of a skilled trades screening package. Requirements change based on the trade, the credential it carries, and the sites the work takes place on.
| Screening Component | What It Covers | Recommendation |
|---|---|---|
| Licenses, certifications, and training cards, each confirmed with the body that issued it. | ||
| Names and addresses associated with the applicant, which identify where to search. | ||
| Criminal records in the counties where the applicant has lived and worked. | ||
| Broad multi-state coverage that points toward records a county search would miss. | ||
| Past employers and dates, which establish the trade experience a credential implies. | ||
| Driving history. Trades workers drive between sites in company trucks carrying tools. | ||
| Pre-employment testing under state law, employer policy, or a site access requirement. | ||
| Medical evaluation for respirator use, confined space entry, or working at height. | ||
| Lifting, climbing, and endurance testing matched to the tasks of the trade. | ||
| Registry records, checked where the work is inside occupied homes or schools. | ||
| Federal court records, added for federal project work and explosives handling. | ||
| Trade school or apprenticeship completion. Most trades roles have no degree requirement. |
Screening components should always be job-related and consistent with applicable federal, state, and local laws.
Notes on This Package
Driving records matter more than the job title suggests. Trades work moves between locations, and workers drive company trucks loaded with tools and materials. The insurer covering those vehicles generally sets what disqualifies a driver, which puts an MVR in packages for roles nobody would call a driving position.
Work inside occupied buildings changes the exposure. Electricians, plumbers, and HVAC technicians enter homes, apartments, and schools where residents are present and no supervisor is watching. Residential service companies commonly screen more closely than commercial contractors for that reason.
The site can set the standard. Refineries, utility projects, and secured facilities operate contractor qualification programs requiring background checks, drug testing, and safety training for everyone entering. A trades worker may be screened once by their employer and again by the site.
Employment histories are project-shaped. Trades workers move between contractors as jobs finish, so several employers in a few years is normal. Verification also runs into contractors that dissolved between projects. See Construction for how that pattern works.
Four Kinds of Credential
Trades credentials come from four different sources, and each is verified a different way.
State and local licenses
Electricians and plumbers hold individual licenses issued by a state or municipal board after examination and documented apprenticeship hours. The board verifies status directly and publishes disciplinary history. Reciprocity between states is limited, so a licensed worker who relocates may be working under a different classification.
Third-party certifications
Welding qualifications, nondestructive testing levels, and crane operator certifications come from testing organizations rather than governments. Certification confirms a person passed a skills evaluation on a specified date and equipment type. Some welding qualifications lapse when the welder goes a set period without running that process, so a certificate showing no expiration date may still be inactive.
Employer-issued certifications
Forklift and aerial lift certifications are issued by the employer after training and evaluation, as federal safety rules require. No state issues a forklift license and nothing appears on a driving record. A new employer generally re-evaluates rather than accepting a prior employer’s card.
Training cards
Safety training cards document completed hours and are frequently required for site entry. They are verified through the training provider, though identifying that provider from the card is not always possible. These are among the most commonly falsified trades credentials.
Where Screening Changes
The same trade carries different requirements depending on the setting.
| Construction | Site owners set access requirements reaching every worker regardless of employer, and screening flows through the subcontract. |
| Manufacturing | Maintenance technicians work inside plants, where hazards drive medical requirements and export controlled areas restrict access. |
| Hospitality | Maintenance staff hold master keys and enter occupied guest rooms, which places them in the property’s access tier. |
| Education | Trades contractors working on school property are covered by district requirements, which can include fingerprinting. |
| Government | Federal facility work requires agency credentialing, and public agency employment adds civil service rules. |
| Distribution | Maintenance contractors hold facility access outside operating hours, and customer security standards set the requirement. |
Screening Considerations
Credential Source
A license verifies through a state board, a certification through a testing organization, a forklift card through the employer, and a training card through the provider. Each has a different renewal rule and a different failure mode.
License Classification
Apprentice, journeyman, and master classifications carry different authority, and reciprocity between states is limited. A relocated worker may hold a different classification than their prior state granted.
Continuity Requirements
Welding qualifications can lapse after a set period without performing that process. A certificate with no expiration date on its face may still be inactive.
Driving and Vehicle Use
Company trucks carrying tools between sites put driving records in the package. Vehicles above the federal weight threshold in interstate operation add a driver qualification file.
Occupied Building Access
Service work inside homes, apartments, and schools puts workers in unsupervised contact with residents. Sex offender registry and property offense screening receive closer attention for those roles.
Site Access Programs
Refineries, utilities, and secured facilities run contractor qualification programs with their own screening and training requirements. A worker may be screened by the employer and again by the site.
Medical and Physical Requirements
Respirator use, confined space entry, and work at height carry medical evaluation requirements. A medical examination belongs after a conditional offer and must apply to everyone in the job category.
Union Dispatch
Workers arriving from a hall carry a classification the local verifies. Collective bargaining agreements can govern testing procedures and what an employer may require before dispatch.
Common Questions
Which trades are licensed?
Electricians and plumbers hold individual licenses in most states. HVAC varies, and many trades carry certifications rather than licenses.
Is a forklift certification a license?
No. The employer issues it after training and evaluation. No state issues one and it never appears on a driving record.
How is a welding certification verified?
Through whichever body issued it. Some qualifications lapse after a period without performing that process, so a current-looking certificate may be inactive.
Why check driving for a trades role?
Because crews drive company trucks between sites. The insurer covering those vehicles generally sets what disqualifies a driver.
Does a license transfer between states?
Sometimes, through reciprocity agreements that vary widely. A relocated worker may need to test again or work under a different classification.
Can a safety training card be verified?
Through the training provider that issued it, though identifying the provider from the card is not always possible. These cards are commonly falsified.
Why screen residential service workers closely?
Because the work happens inside occupied homes without supervision. Registry and property offense screening carry more weight in that setting.
Who screens for site access?
The employer runs the checks, and the site owner sets the standard through the contractor qualification program. A worker cleared for one site may not qualify for the next.
Worth Knowing
Some Trade Licenses Belong to the Company
HVAC and general contracting licenses are usually held by the business through one qualifying individual who met the experience and examination requirements. The crew works under that license, so a license search on an applicant often returns nothing.
