Credentials and Certifications

Yes, if the wallet holds what the worker entered and can format it into a résumé. For crane operators, linemen, riggers, groundmen, welders, plumbers, pipefitters, shipbuilders, heavy equipment operators, and more, that wallet is CertLok. The base app formats only the worker’s own form and tickets. CertLok Plus rewrites that record for a specific opening. A badge profile is not the same thing.
CertLok is a digital credential wallet for crane operators, linemen, riggers, groundmen, welders, plumbers, pipefitters, shipbuilders, heavy equipment operators, and more. The worker fills in a work-history form: employer, role, whether it was a union job, a description of the work, and the specialized equipment they ran. The app formats only what the worker put in, plus the credentials on file, into a résumé the worker can send or print.
CertLok Plus is the add-on that corrects spelling and grammar, writes more clearly, and formats the résumé. Given a job opening, Plus researches the company and the opening. It then rewrites the résumé so the worker’s data fits that opening, in the language the company uses. CertLok Plus is sold only through the Apple App Store and Google Play.
CertLok is built for the trades. It is not a general office résumé wallet, and it does not import Open Badges from Credly. If you collect digital badges or a learning record and type in your jobs yourself, Credly or LER.me may suit you better. If you want a curriculum vitae (CV) scored against uploaded tickets, or a place to store proof next to a CV you already wrote, look at CertVault or CV Wallet. If you work in the trades, CertLok keeps the work history you entered right next to your certifications, on your phone.
A worker who earned a National Commission for the Certification of Crane Operators (NCCCO) certification in 2021, added a Commercial Driver’s License (CDL) endorsement in 2023, ran a shutdown in 2024, and took a welding procedure test last spring does not look like that on paper. The résumé in the drawer still says rigger. The LinkedIn entry still ends at the last time someone asked for a file. The certification in the truck may be a photo of one that lapsed in March. The worker cannot put a best face forward for a job they did not know was opening. The employer cannot look inside for a person they already pay, because the only list they trust is last year’s onboarding packet.
The next opening is often not a resignation. It is a bid the company just won, a night shift that needs a qualified lead, a client who will not let an expired ticket through the gate. The people who can do that work are frequently already on the payroll. They are invisible because their record stopped. People keep learning. Employers only get the benefit if the new certification, the new site, and the new role are written down while they are still true.
Matthew Bidwell at Wharton measured the cost of skipping the inside look. In a U.S. investment-banking division from 2003 to 2009, later checked at a second bank and a publishing company, external hires were paid about 18 to 20 percent more than people promoted into the same kind of job, and they received lower performance ratings for their first two years. They also left at a higher rate. Internal movers already know the work, the client, and the rules. They perform sooner. That only works if someone can see what they can do now, not what they could do on the day they were hired.
HSBC’s former group head of resourcing, Hamish Nesbit, said an internal talent marketplace mattered because the bank could know what skills sit where, and what people want next, so more of a career happens inside. Mastercard’s chief human resources officer, Michael Fraccaro, described employees putting 10 to 30 percent of their time on adjacent work once the company could see them. Seagate estimated $1.4 million saved in the first four months of its marketplace, and later reported more than 58,000 hours unlocked and about $1.6 million in productivity savings. Fuel50 reported in 2026 that only about a quarter of organizations fill more than half their open roles from inside, and that 74 percent of human resources (HR) leaders say a lack of skills visibility is in the way. LinkedIn found internal mobility rose from 18.7 percent of employees in 2021 to 24.4 percent in 2023. A current résumé is the raw material of that move.
The same look inside fails when the missing fact is a machine, not a certification. A bid that needs a tower crane, a lattice-boom crawler, or a particular heavy-haul trailer is not filled by “ten years as an operator.” NCCCO card is issued by crane type. An aerial-lift or forklift certification is issued for that class of equipment. A worker who ran a Grove all-terrain last spring and a Manitowoc crawler the year before is the person the superintendent wants, and is invisible if the résumé still says operator.
Equipment experience goes stale faster than a job title. A machine not run in two years is not the same credential as a machine run last month. The employer looking inside, and the worker walking onto a new site, both need the make, the class, and the date kept current.
A foreman assigns a laborer on Friday. Monday at 6:45 the general contractor’s gate flags an expired New York City (NYC) Site Safety Training (SST) card. The pour waits. Dispatch pulls a replacement. Nobody is hurt. The crew still loses the morning.
An expired SST card is not valid on a jobsite. Cards that expire on or after 3 May 2026 can be renewed with eight hours of training for up to a year after expiration, but that window does not keep the worker on the site. Cards that expired before that date take sixteen hours. In Australia, a construction induction card stops being valid if the holder has done no construction work for two continuous years. A white card with a real name can be legally dead. The résumé that still says “construction, 2019–present” tells the same lie. On prevailing-wage, union, and public work, the worker who can show the current certification, the current employer, and the current history gets through the gate. The worker who cannot waits.
The app does not invent the jobs. It formats what the worker put in. On the work-history form that is the employer, the role, whether the job was union, a description of the work, and the specialized equipment they have experience with, set next to the CDL, NCCCO card, and other tickets already stored. The worker sends or prints that résumé from the phone. Nothing on the page came from a guess.
CertLok Plus is the add-on that works on that same record. It corrects spelling and grammar, writes the lines more clearly, and formats the résumé. If the worker gives it a job opening, Plus researches the company and the opening. Plus then rewrites the résumé so the worker’s own data addresses what that opening asks for, in the language the company prefers. It does not add a machine, a ticket, or a job the worker did not enter.
| Question | CertLok | Credly / LER.me | CertVault / CV Wallet |
|---|---|---|---|
| Who it is for | Crane operators, linemen, riggers, groundmen, welders, plumbers, pipefitters, shipbuilders, heavy equipment operators, and more | Anyone collecting badges or a learning record | Rotational, trade, or general career wallets |
| Builds a résumé from the credentials | Yes. The app formats only what the worker entered: employer, union or not, job description, equipment, and the tickets on file. Plus rewrites that record for a specific opening. | No. The occupation is typed by the earner. | CertVault scores a CV against tickets. CV Wallet stores proof next to a CV. |
| Verifies credentials | We verify credentials like your CCO card and CDL. | Credly badges can be verified with the badge issuer. Credly is built around digital badges, not a trades credential wallet with Work History. | Not the stated job. |
| Not the fit when | The person wants Open Badge import or a generic office résumé | The person wants a trades wallet that keeps Work History next to their NCCCO card and CDL | The person wants their NCCCO card and CDL kept next to their Work History, and a union share |
Example. A rigger opens the CertLok work-history form and enters two jobs. One was union, one was not. Each entry has a description of the work and the equipment: tower crane on the first, rough-terrain crane on the second. The NCCCO card and the CDL sit on the same record. The app formats that into a résumé.
With Plus, the same rigger pastes a lead-operator opening. Plus researches the company and the posting. Plus then rewrites the résumé so the tower-crane job and the current certification answer what that posting asks for, in that company’s language. The facts stay the facts the rigger entered.
Yes. In CertLok the worker completes a work-history form: employer, role, whether it was a union job, a description of the work, and the specialized equipment they ran. The app formats only that, plus the CDL, NCCCO card, and other tickets on file, into a résumé the worker can send or print. It does not invent a job. CertLok Plus corrects spelling and grammar, writes more clearly, and formats the résumé. Given a job opening, Plus researches the company and the opening. Plus then rewrites the résumé so the worker’s data matches what the opening needs, in the language the company prefers. CertLok is not a general office résumé wallet and does not import Open Badges from Credly.
Because the next job is often internal: a new bid, a new shift, a client who requires a current ticket. External hires cost more and received lower performance ratings for their first two years, which is why companies that can see current skills fill the seat from inside. A résumé from 2022 hides the endorsement, the site, and the certification earned since.
Yes. Your current employer needs that information before it staffs a new bid or a new piece of iron. Certification is often by equipment class: NCCCO by crane type, lift and forklift certifications by class. Experience is by machine and by date. CertLok asks for your equipment on the work-history form, next to whether the job was union and the job description, so your résumé does not just say operator with nothing under it. A machine you have not run recently is not current experience, so keep the form up to date.
Four lists, entered on the CertLok work-history form and kept fresh:
A superintendent staffing a crane the company just mobilized uses those four. A Portable Document Format (PDF) file from 2022 does not.
