Planning for the Day Your Only Level III Is Gone

The risk that lives on one person's calendar

An inspection company with a single Level III has concentrated its approval authority, its examination authority, its procedure authority and frequently its radiation safety authority in one individual. That is efficient until the individual gives notice, takes a better offer, has a stroke or reaches sixty-five. Owners insure the building and the vans and leave this exposure entirely uncosted, largely because nothing about it appears on a balance sheet until the week it converts into stopped work and a client phone call.

The demographics make it worse. O*NET's May 2025 data puts the median annual wage for Non-Destructive Testing Specialists at $78,350 and projects growth of one to two percent through 2034, with roughly 5,700 openings across the decade. A slow-growing occupation with a heavily experience-gated senior tier means the replacement pool for a Level III is thin, and it is thinnest exactly where mid-sized inspection contractors compete for the same handful of people.

The right time to build the plan is while the incumbent is still in post and cooperative. A departing Level III who is leaving on good terms will sit down for two days and hand over exam banks, grading keys, procedure rationale and the reasoning behind the practice. A Level III who is leaving badly, or who is no longer available at all, hands over nothing, and the company reconstructs from files it hopes are complete.

What stops at five o'clock on the last day

Approval authority stops. SNT-TC-1A places the review and approval of the written practice with the employer's NDT Level III, and places the approval of in-house examination questions there as well. From the departure date, no revision to the practice is validly approved, no new examination is issued or graded, no new procedure is approved and no technician is qualified. Every one of those is a forward-looking freeze rather than a retrospective invalidation, which is the distinction that matters commercially.

The individual's own employer certification is revoked with employment. SNT-TC-1A treats employer-based certification as ending when employment ends, unless the person holds a third-party credential. Their ASNT NDT Level III certificate is exactly such a credential, and it leaves with them, because ASNT issued it to the person. Nothing about that certificate is recoverable by the company, which is why the succession asset is the relationship rather than the paperwork.

Contract clauses bite next. Client contracts and framework agreements routinely require a named Level III, and some require notification of any change within a fixed window. Read those clauses before the departure, not after. A firm that notifies its three largest clients proactively, names the interim cover and attaches the successor's credentials, holds the contracts. A firm that says nothing and gets discovered at the next audit is treated as having concealed a change in a contractual condition.

What survives, and why re-certifying everyone is the wrong reflex

The instinct after a departure is to re-examine the whole workforce. Resist it. Under SNT-TC-1A the employer certifies personnel and the Level III qualifies them, so the certifications already issued are the company's certifications and they survive the individual's exit. Re-examining thirty technicians costs weeks of billable capacity, produces no additional compliance, and signals to a client that the company itself doubts the validity of the records it issued.

What the incoming Level III owes is a documented review. They sample the certification files, confirm that training hours, experience hours, examination records and vision records reconcile with the written practice in force at the time of signing, and record their acceptance of the population. Where a file fails to reconcile, that individual is remediated. That produces a short, dated acceptance memo that an auditor reads as a controlled transition rather than a gap.

Procedures follow the same logic. They stay in force as approved documents and work continues against them. The incoming Level III reviews the procedures in active use on live contracts first, records acceptance, and takes ownership of subsequent revisions. Re-issuing the entire procedure set on day one creates a wave of revisions with no technical driver, and revision churn without a driver is itself something auditors ask questions about.

Transferring the designation: the paperwork that carries authority

The designation transfer is four documents and it takes an afternoon when it has been prepared. First, the employer's certification of the incoming Level III, signed by the authorised company signatory, with the qualification evidence attached. Second, the incoming Level III's review and re-approval of the written practice, dated. Third, a procedure acceptance record listing every active procedure and its accepted revision. Fourth, a certification population acceptance memo covering the existing certified workforce.

Where the incoming cover is contracted rather than employed, the split between qualification and certification has to be explicit on every record. The outside Level III states that the examinations were passed and the criteria in the written practice met; the employer's authorised signatory issues the certification. Getting this wrong in either direction, by having the consultant sign as certifying authority or by having the company sign as qualifying authority, is a finding that repeats through every file it touches.

Write the transfer procedure into the written practice while nobody is leaving. A practice that names the role, the alternate, the records custodian and the transfer steps converts a crisis into a checklist. This is the part that written practice development frequently skips, because most practices are written to satisfy an audit rather than to survive a departure, and the two are not the same document.

Records custody: what must not leave in a personal laptop

Ownership is settled and custody is the problem. Certification files, examination masters, grading keys, question banks, OJT logs, vision records and calibration records are company records. In practice, a large share of them live in the Level III's own filing: the exam bank in a personal spreadsheet, the grading keys in an email folder, the OJT sign-offs in a notebook, the procedure rationale nowhere at all. When that person leaves, ownership is irrelevant if custody was never established.

Fix custody with three moves. Name a records custodian in the written practice who is not the Level III. Hold every master document, examination bank and grading key in a company-controlled system with access logging, so that a departure is an access revocation rather than a recovery operation. Require examination masters to be deposited centrally at the point of approval, not at the point the Level III gets around to it.

Security of examination content is the one real tension. Question banks need restricted access to stay valid, which is the argument every Level III uses for keeping them personally. The answer is restricted central storage rather than personal storage: the custodian controls access, a second named individual holds break-glass access, and the bank is versioned. That satisfies both the integrity requirement and the continuity requirement without asking anyone to choose.

The radiography case: an RSO change is a licence transaction

When the departing Level III also holds the Radiation Safety Officer role, the succession problem stops being an internal matter. Industrial radiography licensees operate under 10 CFR Part 34 or the equivalent Agreement State rules, and 10 CFR 34.42 sets the RSO's qualifications: the training and testing of 34.43(a), 2,000 hours of hands-on experience as a qualified radiographer, and formal training in establishing and maintaining a radiation protection programme. Not every Level III meets that.

The RSO is named on the licence, and changing the named individual is a regulatory transaction rather than an internal memo. Texas DSHS, an Agreement State regulator, states that a licensee applies for and receives a licence amendment before making changes to the radiation protection programme, including a change of RSO. Timing is set by the regulator's queue, so a firm that identifies and qualifies an RSO successor in advance keeps radiography running; one that starts on the departure date does not.

Reciprocity work compounds the exposure. Under 10 CFR 150.20 an Agreement State licensee working in NRC jurisdiction files NRC Form 241 at least three days before the first activity in a calendar year and is limited to 180 days of such activity per calendar year. Those filings reference the licence, and the licence references the RSO. A stalled amendment therefore reaches out and stalls the out-of-state work as well.

Cover on the day it happens

The gap between a departure and a permanent hire is the dangerous window, and it is measured in months rather than weeks. An interim NDT Level III closes it: the practice is re-approved, examinations resume, procedures get approved, and the client-facing named Level III requirement is satisfied while recruitment runs at a sensible pace rather than a panicked one. Firms that appoint under pressure hire the available person rather than the right person.

Set the boundaries of that cover in writing before it starts. The outside Level III qualifies and approves; the employer certifies. Contracted cover reaches approval of the practice, procedure approval, examination setting and grading, personnel qualification, audit support and technical arbitration. It does not reach issuing the employer's certification, and it does not automatically reach the RSO role. The limits are set out in what an outside Level III can and cannot do.

If the departure has already happened, the sequence is different from the one on this page, because triage comes before planning. The immediate actions, in order, are covered in what to do when your NDT Level III has resigned. Everything here is the work that makes that page unnecessary, which is why it belongs in a normal quarter rather than in a crisis week.

Bench depth and the four-year clock on growing your own

Growing a Level III internally is the durable answer and it is slow, so the clock starts long before you need it. ASNT's eligibility routes are 12 months of NDT experience with a four-year engineering or science degree, 24 months with two years of post-secondary study in those fields, and 48 months with no degree. Those are the minimums before a candidate sits the Basic examination and at least one Method examination.

Pick the candidate early and fund the path. Identify a Level II with three or more methods and the temperament for documentation, put the ASNT Level III examination fees and study time into the training budget as a recurring line, and give them real programme work: drafting procedure revisions, building examination questions under supervision, running internal audits. A candidate who has never written a procedure will pass the Basic examination and still be unable to run a programme.

Maintenance also has a clock. An ASNT NDT Level III certificate renews on a five-year cycle, either by documenting a minimum of 25 renewal points across the 60-month period or by re-examination in each certified method before expiry. Track that date for every Level III in the company the same way you track technician recertification, because an expired Level III certificate under a CP-189 programme is the same problem as no Level III at all.

A twelve-month succession plan you can actually run

Months one to three: document the exposure. List every authority the incumbent holds, including practice approval, procedure approval, examination authority, personnel qualification, RSO and any client-named roles. Read the Level III clause in every live contract. Inventory where each master record physically lives. Most owners find at this stage that between a third and a half of the programme's controlling documents sit outside company systems.

Months four to eight: remove the concentration. Name a records custodian and migrate exam banks, grading keys and OJT masters into company-controlled storage. Amend the written practice to name a role and a designated alternate rather than a single individual, and to define the transfer steps. Certify the alternate, whether internal or contracted, so their authority exists in advance. Identify and start the RSO successor's qualification if radiography is in scope.

Months nine to twelve: test it. Run a week with the alternate exercising full authority while the incumbent is unavailable, then audit the result. Confirm the practice, procedures, examinations and certifications all reconcile under the alternate's signature.
