In more detail

Atlantis consulting covers written practice authoring, NDT procedure development and demonstration, examination writing and grading, retained or interim Level III cover, programme audits and gap assessment, programme build for new inspection firms, and Level III succession. Work runs across SNT-TC-1A, CP-189, NAS 410, EN 4179 and ISO 9712. Method scope decides who can sign what.

Every engagement resolves to a document somebody has to defend. The written practice is the root: SNT-TC-1A requires the employer to prepare one and have it approved by the employer's Level III, and every certificate the company issues traces back to it. Procedures sit under that, approved by a Level III and, where the referencing code demands it, demonstrated before an inspector under ASME Section V Article 1 T-150. Examination records sit under those. The regime is chosen by the customer contract, not by preference: aerospace and Nadcap work invokes NAS 410 or EN 4179, contracts naming ANSI/ASNT CP-189 impose a standard written in shall rather than a recommended practice written in should, and ISO 9712 replaces the employer scheme with third-party certification held by the individual. Scope from the artefact backwards and the regime becomes an input, not an argument.

The engagement catalogue, in full

Consulting enquiries land as one of eight jobs, and naming which one you have shortens everything that follows. Written practice authoring. Procedure development and demonstration. Examination oversight. Retained Level III cover. Interim cover after a departure. Programme audit and gap assessment. Programme build from zero. Succession before a named Level III leaves. Each ends in a specific artefact somebody has to defend in front of an auditor or a client, and each is scoped backwards from that artefact rather than forwards from a task list.

Two more sit alongside the eight and are frequently the real requirement behind an enquiry. NDT report validation is an independent technical review of inspection reports before they are issued, or after a client has challenged them — faster than a programme engagement and often the thing that was actually broken. Independent second opinions on disputed calls belong in the same category: one technical question, answered in writing, with the reasoning attached so it survives being forwarded.

The catalogue also has an edge, and it is worth stating. Where the honest answer is that no consultant is needed — the programme is sound, the finding is routine, the existing records already support the decision — that is the answer given. An engagement producing a document nobody uses is worse than no engagement at all, because it becomes a document an auditor will read and hold you to.

Written practice: the document everything else hangs from

The written practice is the root document. SNT-TC-1A requires the employer to prepare a written practice for qualifying and certifying its own NDT personnel, and requires that document to be on file and approved by the employer's Level III. Every certificate the company issues, every qualification decision and every examination score traces back to it. It is also, without exception, the first document a client or accreditation auditor asks to see when they walk in.

A defensible written practice states the methods and levels covered, training hours and documented experience by level and method, examination structure and passing criteria, near-vision and colour-contrast requirements, the recertification cycle, and records retention. Where it goes wrong is rarely omission — it is drift. A practice written against one edition, examinations run against another, and technicians qualified under rules the current document no longer contains. Candidates sitting Basic examinations after 1 January 2026 work to the 2024 editions of SNT-TC-1A and CP-189, which replaced the 2020 editions in ASNT's reference list.

Authoring is one document cycle; keeping it current is an annual review triggered by scheme changes, new methods, new contracts and new regions. Written practice development covers what goes into the document and how an employer formally adopts it. The regime it is written against, and what SNT-TC-1A does and does not require, is set out at the SNT-TC-1A compliance hub.

Procedure development and the demonstration that qualifies it

Procedures sit directly under the written practice, and a Level III approves them. ASME Section V Article 1 T-150 requires written procedures for the examinations it governs, and requires a revised procedure to be prepared and approved by a Level III whenever an essential variable changes. That clause is the reason procedure control fails quietly rather than loudly: a technique is adjusted in the field, an essential variable moves, and the procedure on file no longer describes what was actually done on the job.

Where the referencing code section requires it, a procedure is also demonstrated — run on representative geometry, controlled by a Level III, witnessed by the inspector, and documented. Most ASME sections require demonstration to the Authorized Inspector rather than formal qualification, and the distinction matters because the two generate different records. Procedures are written narrowly enough to be demonstrable and broadly enough to cover the work you actually sell, which is a drafting skill rather than a code lookup.

Multi-method programmes need this repeated per method and per technique. UT, PAUT, TOFD, RT including digital and computed radiography, MT, PT, VT and ET each carry their own essential variables and their own demonstration expectations. A procedure set assembled from mixed sources — some inherited from a previous employer, some copied from a client, some written in-house years ago — is the most common finding in a first client audit and the slowest to close.

Examination oversight: writing, administering, grading, retaining

SNT-TC-1A assigns the Level III responsibility for approving and grading the examinations administered for certification. In practice that means three artefacts: a question bank matched to the method and level being claimed, an answer key, and graded papers retained with scores, dates and invigilation records. Practical examinations add a specimen set with known indications and a recorded result against them, which is the part most often missing when a programme is inspected.

The examination record is where programmes fail an audit most often, and rarely because the examination itself was wrong. It fails because the papers were not retained, because the specific examination did not match the method or level claimed, or because the grading carries no signature behind it. An auditor is not assessing whether your technician can perform UT. They are assessing whether you can prove how you concluded that they could.

Examination oversight is scheduled against your qualification calendar rather than run continuously, which is exactly why it suits an outside arrangement. New hires, recertification cycles and new method additions cluster together; between clusters the workload does not justify a permanent appointment. Under SNT-TC-1A the recommended maximum recertification interval is five years across Levels I, II and III, which makes the calendar predictable enough to plan cover around.

Level III cover: retained, project and interim

Level III cover comes in three shapes, and choosing the wrong one is the usual source of friction later. Retained cover names a Level III of record continuously, sized to your qualification calendar and your procedure churn. Project cover attaches to a defined scope — a contract, a procedure set, a single facility — and ends when that scope does. Interim cover fills a hole that has already opened, and is judged on speed and on what it leaves behind.

Retained cover suits firms whose contracts require a named Level III at all times and whose demand is steady but low. Project cover suits EPCs and fabricators with a defined job and a defined end date. Interim cover suits a firm that has just lost its Level III and now cannot qualify a technician or approve a procedure until somebody is designated. Interim NDT Level 3 cover sets out how that gap is closed, how fast, and what the handover has to contain.

In every shape, the arrangement is documented in the employer's written practice. SNT-TC-1A permits an employer to engage an outside agency Level III for technical work provided the arrangement is written down. NAS 410 goes further: the employer identifies a Responsible Level 3 in writing to act on its behalf in qualification and certification matters, and that person may come from an outside agency. The full role is set out under ASNT Level III consulting services.

Programme build for a firm that has none

Firms starting an inspection capability from zero — a new NDT contractor, a fabricator bringing examination in-house, an operator building an owner-inspector function — need a programme designed in sequence rather than assembled as problems appear. The sequence is fixed: choose the regime, write the practice, define methods and levels, build the procedure set, establish training and experience records, then qualify the first technician against all of it.

Doing it in that order costs a fraction of retrofitting it. Doing it in reverse — hiring technicians, taking work, then discovering no document supports what was signed — is how firms end up requalifying people who were competent all along, because the evidence trail behind their qualification was never built. Competence and provable competence are different assets, and only one of them survives an audit or a client's supplier qualification questionnaire.

Programme build pairs naturally with getting people through the levels in the first place. NDT training covers the classroom and practical hours side, method by method; the programme side covers what those hours must be recorded against for the resulting certificate to mean anything to a customer. Building both together means the first cohort qualifies into a programme that already holds their records correctly, rather than into a filing gap discovered two years later.

Audit and gap assessment against the regime that will actually be applied

A gap assessment is an audit you commission against yourself, run against the regime that will actually be applied to you. That qualifier carries the weight: assessing a programme against SNT-TC-1A when the incoming client contract names CP-189 produces a clean report and a failed audit. CP-189 is an American National Standard written in shall; SNT-TC-1A is a recommended practice written in should. CP-189 also carries additional requirements for experience, examinations and record keeping.

The output is a findings list mapped to clause, owner and closure date — not a narrative report that reads well and changes nothing. Findings cluster in four places: written practice currency, procedure control, examination records, and vision test currency. Each has a different fix and a very different lead time. Knowing those lead times before an audit is announced is most of the value, because a missing vision test is a same-week fix and a missing examination paper is a requalification.

Programme audit and gap assessment covers the review itself and the closure support that follows it. Closure matters more than the finding: an audit that produces a list nobody works through leaves the programme exactly where it was, except that documentation now exists proving the firm knew. That is a worse position than never having run the assessment, which is why closure support is scoped into the engagement rather than sold separately.

Succession, and the gap that opens when a Level III leaves

When a named Level III leaves, existing certifications remain valid and the approving authority disappears. Until a replacement is designated in the written practice, no new technician can be qualified and no procedure can be approved or revised. Work continues normally until the first procedure change or the first new hire — and then it stops, usually on a week when a client is waiting and nobody has time to run a recruitment process properly.

Succession planning removes that cliff. A named deputy, an overlap period, a transferred record set and a documented handover convert a resignation into an administrative change. The handover pack is the part that gets skipped: examination question banks, procedure revision history, demonstration records and the reasoning behind non-obvious technique decisions all live in one person's head until somebody sits down and writes them out.

Where the departure has already happened, interim cover closes the gap while recruitment runs, and the interim Level III builds the handover pack the permanent appointment will inherit. That sequencing matters more than it looks: an interim engagement that leaves nothing behind recreates the identical cliff eighteen months later, with the same client, the same procedure queue and the same week of lost work.

The method scope constraint that decides who can sign what

Level III certification is granted per method, and authority is bounded by the methods held. A Level III certified in UT and MT can approve UT and MT procedures and grade UT and MT examinations. That signature does not extend to RT or ET, however senior the individual or however long they have worked in the industry. Programmes selling six methods need six methods covered, whether by one person holding all six or several holding a few each.

This is the constraint that quietly invalidates arrangements. A firm engages a Level III, adds a method eighteen months later, and the new method's procedures carry a signature that does not cover them. Every scope statement should list the methods in scope, the regime under which each was certified, and the expiry date. ASNT NDT Level III certifications are renewed on a five-year cycle, either through documented recertification points or by re-examination in each method held.

The regime layer sits above the method layer. SNT-TC-1A and CP-189 are employer-based: your company certifies its own people against your own written practice. ISO 9712 inverts that — an accredited body examines and certifies the individual, and the certificate travels with that person between employers. Many inspectors hold both, SNT-TC-1A for US work and ISO 9712 for international mobility. A programme mixing the two without saying so is the finding an auditor writes first.

How an engagement starts

An engagement starts with a scoping call that establishes four things: the artefact you need at the end, the date somebody is waiting for it, the regime your customer contract names, and the methods in scope. Those four determine everything downstream — delivery model, sequence, and which of your existing records can be reused rather than rebuilt from scratch. Firms consistently underestimate how much of their existing evidence is usable once someone knows what to look for.

Most documentation work runs remotely. Written practice authoring, procedure development, examination banks and gap assessment need your documents and your answers, not a site visit. Site presence is reserved for what genuinely requires it: technique demonstrations on representative geometry, practical examinations, and audit attendance. That split keeps engagements lean regardless of where the facility sits, and keeps the schedule driven by your calendar rather than by travel.

Affordable, accessible, fully customizable — and scoped in writing before anything begins. Start with a scoping conversation; demo and quote on request. Bring the contract clause that triggered the enquiry if there is one, because the clause usually names the regime, the methods and the acceptance standard, and settles half the scoping questions before the call has ended.

Frequently asked

Can an outside consultant certify our NDT technicians?

No. Under SNT-TC-1A, certification is an act of the employer and cannot be transferred to an agency. An outside Level III authors the written practice, prepares and grades examinations, approves procedures and provides method oversight — the entire technical chain. Your company signs the certificate, holds the training and experience records, arranges the vision examinations and retains everything for audit. Auditors ask the employer to produce that evidence, never the consultant.

Which standard should our written practice be written against?

Whichever one your customer contracts name. Aerospace and Nadcap-accredited work invokes NAS 410 or EN 4179. Contracts specifying ANSI/ASNT CP-189 impose a standard written in mandatory language, with additional requirements for experience, examinations and record keeping. Absent an explicit clause, SNT-TC-1A employer-based certification is the default across US industrial work. Declare the choice explicitly in the document and apply it consistently — mixed programmes are the finding auditors write first.

How quickly can a written practice or a procedure be turned around?

Turnaround is driven by how complete your inputs are, not by the drafting. A procedure written against a code you can name, for a geometry you can describe, with acceptance criteria already fixed by contract, moves fast. A written practice for a firm that has to first decide its regime, its methods and its levels takes a cycle of decisions before drafting starts. Site-dependent work — demonstrations, practical examinations — schedules around access.

Do you work outside the United States?

Yes. The United States is the primary market, and engagements run across other Western markets on the same basis. Documentation work is regime-specific rather than location-specific: SNT-TC-1A and CP-189 travel with US contracts, NAS 410 and EN 4179 with aerospace supply chains, ISO 9712 where a customer requires third-party certification. Remote delivery covers most of the work; site presence is scheduled where demonstrations, practical examinations or audit attendance require it.

What do you need from us to start?

The trigger — an audit notice, a contract clause, a resignation, a rejected procedure. Your current written practice if one exists, the methods you perform, the codes your work is governed by, and the customer specification that prompted the enquiry. That is enough to name which of the eight engagements you have and to write a scope. Nothing begins before the deliverable and the date are written down and agreed.
