Personnel Certification Tracking for NDT Technicians
NDT certification tracking software maintains a matrix of every technician against every method and level — UT II, MT II, RT I — each cell carrying its own expiry date under the employer's SNT-TC-1A written practice. Layered on top: annual near-vision exams, color-vision records, and OJT hour accumulation toward the next level. The assignment gate blocks scheduling any technician whose required credential lapses before the job ends.
Under SNT-TC-1A, certification belongs to the employer, not the technician — which means every US inspection company runs its own certification system and owns the paperwork burden that comes with it. One technician certified UT Level II, MT Level II, and PT Level II is three certification records, three expiry dates, one annual near-vision exam, a color-vision record, and a running OJT ledger toward RT. Multiply by twenty technicians and the matrix holds well over a hundred live dates, any one of which can invalidate a report if it lapses mid-job. Certification tracking software binds the matrix to the company's written practice, alerts ahead of every expiry, and — the part spreadsheets never do — gates crew assignment, refusing to schedule a technician onto work their current credentials do not cover through the job's end date. Cell by cell, that is the difference between an audit finding and a clean one.

| Credential | Set by | Cycle | Tracked per | When it lapses |
|---|---|---|---|---|
| Method certification, Level I/II | Employer written practice (SNT-TC-1A / CP-189) | Interval fixed in the written practice; 3- and 5-year cycles are the standard choices | Technician × method × level | Blocks assignment to that method only |
| Level III | Written practice; ASNT NDT Level III certificate where held | ASNT certificate renews on a 5-year cycle | Technician × method | Blocks procedure approval and exam administration |
| Near-vision acuity | Written practice, per SNT-TC-1A recommendation | Annual | Technician (row-level) | Grounds the technician across all methods |
| Color / contrast vision | Written practice | Interval set in the written practice | Technician | Blocks contrast-dependent methods (MT, PT) at minimum |
| OJT / experience hours | Written practice tables | Accumulates until the level requirement is met | Trainee × method, running total | Not an expiry — trainee stays supervised and cannot sign results |
| Radiation safety (IRRSP card) | State radiography programs / ASNT IRRSP | 5-year card | Technician | Blocks radiographic work entirely |
| Site credentials (TWIC, client orientations) | TSA / client site | TWIC 5 years; orientations per site | Technician × site | Blocks site access, not the method |
One technician is a stack of expiry dates
Start with one real technician: UT Level II, MT Level II, PT Level II, working toward RT. That is three method certifications, each with its own expiry under the written practice, an annual near-vision examination, a color-vision record, an OJT ledger accumulating radiography hours, plus a TWIC card and two client site orientations. Nine live credentials, six of which can ground him — and every US inspection company holds a stack like this for every technician on the payroll, because under SNT-TC-1A the company itself is the certifying body.
Scale that to a crew of twenty and the matrix crosses a hundred cells of method certifications alone before the vision exams and badges are counted. The failure mode is never ignorance — every Level III knows what the written practice requires. It is arithmetic at scale: some cell in the matrix is red today, and finding it requires checking all of them. That is a software problem, and the near-total absence of credible products addressing it is the gap this page maps.
Rendered properly, the matrix is one screen: technicians down the side, method-level pairs across the top, each cell colored by status with the expiry date visible — green current, amber inside the warning window sized to real renewal lead times, red lapsed. That single view answers the operational question (who can I send tomorrow) and the planning question (whose renewals cluster next quarter) at once, and it is the first screen a client auditor should be shown.
SNT-TC-1A: the employer is the certifying body
The US answer first: American industry certifies NDT personnel under the employer-based model of SNT-TC-1A, ASNT's recommended practice, or its mandatory-language sibling ANSI/ASNT CP-189 where contracts invoke it. The employer writes a written practice, trains and examines its own people, and issues certifications valid only inside that company. When a technician changes employers, the new company certifies them again under its own practice. Aerospace runs the parallel NAS 410 framework; the structure — employer responsibility, controlled document, per-method certification — is the same shape.
Contrast ISO 9712, the central-certification scheme common outside the United States: a certification body examines the person and the credential travels with them. Under that model, a registry tracks expiry for you. Under the US model, nobody outside your company tracks anything — the examination records, the OJT evidence, the vision results, and every expiry date exist only in your files. Employer certification is why certification tracking software is not an optional convenience for a US inspection contractor; it is the certifying body's own record system.
The written practice is the configuration file
Every number the software enforces comes out of one document. The written practice fixes, for your company: initial training hours per method and level, experience hours, examination structure and grading, vision-examination requirements and frequency, interruption-of-service rules, and recertification intervals — with three-year and five-year cycles both standard choices for Levels I and II. Configuring the tracker means transcribing those decisions faithfully: interval per method-level pair, warning windows sized to renewal lead times, OJT targets per method, and the gate rules that act on them.
Bind the versions. Certifications issued under revision C of the written practice should carry that fact on the record, because when revision D tightens an experience requirement, the audit question becomes which certifications were issued under which rules. A tracker that stores the practice edition on each certification record answers in one query. This is also where a Level III earns their retainer: Atlantis's outsourced Level III service maintains written practices and their software bindings for contractors who do not keep a Level III on staff.
Vision examinations: the annual date that grounds everyone
Near-vision acuity is examined annually under SNT-TC-1A-based written practices, and color and contrast differentiation at the interval the practice sets. The operational teeth: a lapsed vision exam does not suspend one method — it suspends the technician, because every method's certification presumes current vision. In the matrix it is a row-level credential, one date that turns every cell in the technician's row red at once, which is exactly why it deserves its own alert stream rather than a note in a personnel file.
Tracking it well means treating the exam as a first-class record: examination date, examiner, the test used, corrected or uncorrected, result, and next-due date. Batch the renewals — an annual company-wide vision day collapses twenty individual expiry dates into one scheduled event, with stragglers visible on the matrix afterward. Size the alert window to how the exams are actually delivered: thirty days is workable when a visit to the occupational clinic closes the gap the same week.
OJT hours: the ledger that starts before the certification exists
Experience accumulation is the untracked half of certification. A trainee's creditable hours accrue shift by shift, per method, under documented supervision, until the written practice's requirement is met and examination becomes possible. The clean implementation ties the ledger to timesheets: a time entry tagged UT on a job under a named Level II supervisor is one creditable increment, captured the day it happened. The alternative — reconstructing two years of hours from memory at exam time — produces exactly the OJT logs auditors challenge first.
The ledger should show, per trainee per method: hours to date, hours required, projected examination date at the current pace, and the supervision trail behind every entry. That projection is workforce planning — it tells the operations manager which month a fourth UT Level II appears and whether the RT pipeline is empty. The hour requirements themselves come from the written practice, built from SNT-TC-1A's recommended tables; /blog/ndt-training-hours-requirements-by-method breaks those requirements down method by method.
The crew-assignment gate: can this tech legally do this job today?
The gate is one question asked automatically at scheduling time: can this technician legally perform this work, today and through the job's end date? Decomposed: does the job's method-level requirement match a current certification; is the vision examination current; for RT, are the radiation-safety credential and dosimetry in place; does the site require badges or orientations the technician holds. Any miss blocks the assignment with the reason displayed — not a warning to click through, a block, for the same reason out-of-cal instruments leave the assignable pool.
The end-date clause is the difference between a gate and a report. A four-week turnaround assigned to a technician whose UT II expires in week three passes every start-date check and fails on site — mid-job, when replacement means demobilizing one person and qualifying another. The gate evaluates expiry against the job's whole window and either blocks the assignment or drives the renewal to happen first. Every report signed by a technician whose certification had lapsed becomes a client-notification conversation; the gate exists so that conversation never starts.
Audit day: what the client's Level III pulls
Certification audits run on sampling: pick two technicians from last month's jobs, produce the files. A complete pull per technician: the current certifications with issue and expiry dates, the examination records behind each — general, specific, practical, with scores and the administering Level III — the vision-examination record, the OJT evidence supporting the level held, and the written-practice edition each certification was issued under. The software's test is producing that pack in minutes, assembled from records that already existed rather than gathered overnight before the audit.
The sharper questions target the seams. Show me anyone who performed work in the gap between expiry and renewal — a query joining certifications to job assignments, and the exact query a company without assignment-gating dreads. Show me the written practice in force in March of last year — version binding again. Auditors who find clean answers to the seam questions shorten the audit, because the sampling is a proxy for whether the system runs itself or runs on heroics.
The renewal pipeline: where tracking meets training
Tracking expiry dates without a renewal pipeline is just scheduled bad news. The working loop: the matrix's amber band feeds a renewals queue; the queue drives examination scheduling and refresher training; completions write back to the matrix. Recertification under the written practice — by examination or by the continuing-performance evidence the practice specifies per level — gets planned in the quarter before expiry and batched where renewals cluster, so the Level III administers one exam session instead of five.
Atlantis runs both sides of that loop: the certification-tracking module inside its Odoo-based NDT ERP, and the Level I, II, and III training programs that feed the renewals queue — see /corporate-ndt-training for the employer-side programs. The combination closes the loop the matrix exposes: the software finds the red cells coming, and the training calendar erases them before they arrive. Affordable, accessible, fully customizable, with a demo of the matrix built against your own roster available on request.
What does the certification expiry matrix actually look like?
Rows are technicians; columns are method-level pairs — UT II, MT II, PT II, RT I, VT II; each cell holds an expiry date and a status. A twenty-technician shop running five methods manages a hundred-cell matrix before counting vision exams, radiation-safety cards, and site badges. Software renders it as a heat map — green current, amber inside the warning window, red lapsed — so the renewal pipeline plans itself off one screen.
How is SNT-TC-1A certification different from ISO 9712?
SNT-TC-1A is employer-based: your company certifies its own technicians under its own written practice, and the certification dies when the technician leaves. ISO 9712 is central certification — a body certifies the person, portably. US industry runs on the employer model, which is exactly why tracking software matters here: every US inspection company is its own certifying body, holding examination records, OJT ledgers, and expiry dates that no external registry maintains for it.
How should annual vision examinations be tracked?
As a separate credential per technician with its own expiry, because it lapses independently of every method certification and takes all of them down with it. SNT-TC-1A-based written practices call for near-vision acuity examination annually, with color and contrast differentiation testing at the interval the written practice sets. The tracker alerts ahead of the date, stores the examination record, and gates assignment the day it lapses — a lapsed eye exam grounds the technician, not one method.
How does software accumulate OJT hours toward the next level?
Hours flow from timesheets: each time entry tagged with a method becomes creditable experience against the trainee's running total, split by method, with the supervising Level II or III identified. The ledger shows hours-to-date against the requirement in the written practice, so the Level III sees exactly when a trainee becomes examinable. Hand-built OJT logs assembled at exam time are the alternative, and they are the records auditors challenge first.
What is the crew-assignment gate?
A scheduling rule that answers one question before a technician lands on a job: does this person hold every credential the job's methods require, valid through the job's end date, not just its start? The gate checks method certifications, vision status, radiation-safety credentials for RT, and site badges, and refuses the assignment on any miss. The end-date check is the part manual scheduling gets wrong — a certification expiring mid-turnaround fails silently until the client's auditor finds it.
Why does the written practice drive the software configuration?
Because under SNT-TC-1A the written practice is the law of your certification program — it fixes training hours, experience hours, examination composition, vision requirements, and recertification intervals for your company. The software must be configured from that document, not from a vendor's defaults: intervals, warning windows, OJT targets, and gate rules all trace to written-practice sections. Version-bind each certification to the practice edition it was issued under; when the practice is revised, the bindings show which certifications need review.
Built for any business that runs on operations
Most companies do not fail at their craft. They lose time, margin and goodwill in the gaps between the tools they use to run the place — a quoting spreadsheet that does not talk to the job sheet, a job sheet that does not reach accounts, and a compliance folder nobody can search when a client asks. Atlantis closes those gaps by putting the whole operation on one platform, so information is entered once and everything downstream stays in step.
What you can run on it
- Sales and CRM — leads, quotes, follow-ups and the pipeline that tells you what next month looks like.
- Projects and job costing — plan the work, track the hours and materials against it, and see the margin while the job is still live rather than at final account.
- Field and service teams — dispatch, schedules, mobile capture that works with no signal, and sign-off from site.
- Inventory and purchasing — stock, suppliers, reorder points and goods receipt, joined to the jobs that consume them.
- People — records, qualifications and licences with renewal reminders, timesheets, leave and payroll.
- Quality and documents — procedures and forms under revision control, with the audit trail an inspection or accreditation body actually asks for.
- Accounts — invoicing, expenses, multi-currency and the reporting your accountant stops chasing you for.
Affordable, accessible, fully customizable — and we mean each word
Affordable because the whole suite is included rather than sold to you a module at a time, and because implementation is done by people who have run operations rather than by a chain of subcontractors. Accessible because it runs in a browser and on a phone, works for a small team on day one, and does not need a specialist on staff to keep it alive. Fully customizable because your process is the thing that makes you competitive — the software should bend to it, not the other way round.
Industries we configure for
Service businesses and contractors, manufacturing and fabrication, trading and distribution, laboratories and testing houses, engineering consultancies, construction and facilities, and asset owners across energy, marine, aerospace and infrastructure. Inspection and testing is where we started, and it remains the sector we go deepest in — but the platform underneath is general-purpose, and most of what it does has nothing to do with inspection at all.
What happens when you get in touch
A short conversation, not a sales sequence. We ask how the business runs today and where it hurts, show you the platform doing that work, and send a written quote shaped to your region, your team size and the scope you actually need. No obligation, nothing to install first, and no pressure to decide on the call. Reach out and tell us what you are trying to fix.
