On a trades resume the certification block is not a footnote — it is the part that decides whether you are legally allowed on the site, and it is what automated screening software looks for first. Knowing how to list certifications on a resume properly is worth more than any amount of polish elsewhere on the page.
This page covers the anatomy of a correctly written certification, a trade-by-trade reference of what matters, and how to handle the two situations people get wrong most often: lapsed cards and foreign qualifications.
What a correctly written certification block looks like
CERTIFICATIONS OSHA 30-Hour Construction - 2024 NFPA 70E Arc Flash Safety - 2025 AWS D1.1 - SMAW, 3G and 4G, carbon steel - current Ohio Journeyman Electrician Licence #XXXXX - active, renews 2028 Confined Space Entry - 2024 Aerial and Scissor Lift - 2023 First Aid / CPR - current TWIC card - current
Every line has an issuer or code, a scope, and a date or status. Nothing says merely “certified”.
The four parts every certification needs
| Part | Why it matters |
|---|---|
| Exact name and issuing body | “OSHA 30-Hour Construction”, not “safety certified”. Screening software matches on the real name |
| Scope | For welding and electrical this is the whole point — process, position, material, or licence class and state |
| Date earned or expiry | An undated certification is assumed lapsed |
| Status word | “Current”, “active”, “renews 2028” — one word that removes a question |
Where the block goes
- Welders — above experience. The process/position/material string is the qualification for the job. See the welder resume template.
- Electricians — licence and hours go in the header, the rest below experience. See the electrician resume template.
- General construction and equipment — below experience is fine, but OSHA and any card that gates site entry should also appear in the header.
By trade: what actually matters
General construction
- OSHA 10-Hour — frequently the minimum to get on a commercial site
- OSHA 30-Hour — expected for lead hands and supervisors
- First Aid / CPR — sites often need a ratio of certified workers
- Flagger — needed on nearly every road or municipal job
- Scaffold user or competent person; fall protection competent person
- Confined space entry
- Silica awareness, lead and asbestos awareness — asked for on renovation and demolition
- Forklift, aerial and scissor lift
Full worked examples in the construction worker resume example.
Electrical
- Licence or classification with the issuing state, and the number
- Logged apprenticeship hours as a fraction of what is required
- NFPA 70E arc flash — on industrial sites, without it you cannot work on or near energised equipment at all
- OSHA 30 — note whether the posting wants Construction or General Industry
- Lift, confined space, LOTO authorisation
Stage-by-stage detail: helper, apprentice, journeyman, industrial and maintenance.
Welding
- Code: AWS D1.1, ASME Section IX, API 1104
- Process: SMAW, GMAW, FCAW, GTAW, SAW
- Position: 1G–4G, 5G/6G for pipe; 1F–4F for fillet
- Material: carbon steel, 304/316 stainless, aluminium, P11/P22 chrome-moly
- Thickness or diameter and schedule range
- Currency — welding qualifications typically lapse after about six months without welding in that process
Written out in full in the welder resume sample.
Equipment operation
- In the US there is no forklift licence — write “OSHA Powered Industrial Truck, employer evaluated, current” plus the truck classes
- Telehandler and rough terrain operator training
- Rigging and signal person
- Australia uses High Risk Work Licences; the UK uses accredited schemes such as RTITB or ITSSAR
The licence misconception is covered in detail in the forklift operator resume guide.
How to handle a lapsed certification
Do not hide it and do not pretend it is current. Write it honestly with the status:
AWS D1.1 - SMAW, 3G and 4G - lapsed 2025, available to retest OSHA 10-Hour Construction - 2021, renewal booked
This is stronger than silence, because passing a test once is evidence you can pass it again — and every employer knows cards lapse when work is slow. What loses you the job is being caught claiming something current that is not.
A lapsed card is the part people most often get wrong, and it is hard to judge your own wording. If you would rather have someone else phrase it, Resumeble writes trade resumes — HARDHAT10 for 10% off.
Foreign qualifications
Name the certificate, the issuing body and the country, then state the scope in terms a local reader recognises — process and position for welding, voltage and system type for electrical. Then say what you hold or have applied for locally.
If you are confident an equivalence is accurate you can note it in brackets, but do not guess. Requirements and recognition arrangements vary by state and country and change; check with the licensing board or programme in the place you are applying rather than relying on any article, including this one.
What not to put in the certification block
One phrase gives you away faster than any formatting mistake: “OSHA Certified.” OSHA does not certify individual workers. The 10- and 30-hour cards come from its Outreach Training Program — voluntary training delivered by authorised trainers — and the card records course completion, nothing more. Safety managers know this, and they read “OSHA Certified” as a sign the writer has not spent much time near the paperwork. Write what the card actually says: OSHA 30-Hour Construction — 2024.
- Site inductions. Every site has one; it is not a qualification.
- Internal company training with no external issuer, unless it is genuinely unusual.
- Anything without a date. Add the date or leave it out.
- Skills dressed up as certifications. “Blueprint reading” belongs in skills unless you hold an actual certificate for it.
- Certifications for a different trade that have nothing to do with the posting. One line at most.
Frequently asked questions
Should certifications go before or after education?
Before, always. In the trades the card matters more than the schooling.
Do I need to list certification numbers?
For licences, yes — it lets an employer verify against the state board in thirty seconds. For safety cards, the date is enough.
How many certifications is too many?
There is no upper limit if they are real and relevant, but order them by what the posting cares about and put the gating ones first.
What if I have none at all?
OSHA 10 costs little and can be completed online in a day. Getting it before you apply changes which jobs you are eligible for, not just how the resume reads.

If you would rather not write it yourself
Your certification block comes off your cards and test papers. Getting it right is a transcription job, not a writing job.
Do it yourself. A resume builder handles the single-column formatting that application software wants, which is the fiddly part. The content above is what actually persuades, and that part is yours.
Pay someone to write it. Worth it mainly if you are moving into a role where the certifications are the smaller part of the argument – supervision, inspection, estimating. If you go that route, Resumeble is a US-based writing service – where the writer sits matters on trades work, because someone unfamiliar with the trade flattens your specifics into generic phrasing. If you do, the code HARDHAT10 takes 10% off. Expect to be asked for your numbers either way, so do that homework first regardless of which route you take.
