ASNT Level III (Level 3) Consulting & Outsourced NDT Level III Services
Atlantis NDT provides independent ASNT Level III consulting and outsourced NDT Level III services for inspection contractors, owner-operators and EPCs worldwide. Our ASNT Level III professionals author and approve written practices, develop and certify NDT procedures, qualify Level I/II personnel, and provide audit and expert-witness support on a retainer or per-engagement basis.
What our NDT Level III consulting services cover
Written-practice authoring to SNT-TC-1A, CP-189 and NAS 410; procedure development and approval for UT, PAUT, TOFD, RT, MT, PT, ET and VT; personnel certification and eye-exam administration; method and equipment validation; and quality-system audit support for ADNOC, Saudi Aramco, QatarEnergy, NRC and ISO 9712 / Nadcap programs. We act as your responsible Level III services provider so you can bid and execute NDT scopes without carrying a full-time Level III on staff.
Outsourced Level III with a clear SLA
Most procedure reviews and written-practice updates are returned within 2 to 5 business days, signed and stamped. Engagements scale from a single procedure approval to a full multi-method NDT program, billed on a day-rate or retainer basis with a tailored quote for your scope.

In more detail
An outsourced Level III holds technical authority inside your programme without joining your payroll. The work is four recurring signatures: the written practice, each NDT procedure, the examination record, and the qualification recommendation, plus method oversight and audit attendance. Certification itself stays with the employer under SNT-TC-1A and cannot be delegated to any agency, however complete the outside work is.
The role is misread as coverage when it is really custody of a signature chain. SNT-TC-1A requires the employer to prepare a written practice approved by the employer's Level III, and assigns the Level III responsibility for approving and grading qualification examinations. ASME Section V Article 1 T-150 requires written procedures, with a revised procedure prepared and approved by a Level III whenever an essential variable changes. NAS 410 goes further and requires the employer to identify a Responsible Level 3 in writing, a role an outside agency Level 3 can hold. What none of those clauses permits is the outside party issuing the certificate. That stays with the employer, along with training records, documented experience, vision test currency and retained examination papers. An auditor asks the employer for that evidence, and the consultant's name on the procedure does not answer the question.
| Signature | Document it lands on | What it asserts | Outside Level III may sign | Employer must still hold |
|---|---|---|---|---|
| Written practice approval | The employer's written practice | The programme meets the chosen regime | Yes, as the designated Level III | Formal adoption and version control |
| Procedure approval | Each method and technique procedure | The technique is valid for the scope written | Yes | Evidence the revision in force was used on the job |
| Examination approval and grading | Question sets, answer keys, graded papers | The exam matched the method and level claimed | Yes | Retained papers, scores, dates, invigilation record |
| Qualification recommendation | The personnel qualification record | Training, experience and exam results are satisfied | Yes, as a recommendation only | The certificate itself, signed by the employer |
| Technique demonstration record | Demonstration report on representative geometry | The procedure performs on the real part | Yes, controlling the demonstration | The specimen and the witness record |
| Vision examination record | Near-vision and colour-contrast test results | Acuity meets the written practice requirement | No | Arranging, witnessing and retaining the test |
What the role does in a working month
Strip the title away and the role is a queue of small, high-consequence decisions. A procedure arrives for approval because a client changed the acceptance criteria. A technician's qualification comes up because a recertification date landed. A field crew hits a geometry the procedure does not cover and needs a technique variation authorised in writing. A client announces an audit with six weeks' notice. None of these fills a week; every one of them stops work if nobody holds the authority to answer it.
Across a month the recurring items are procedure review and approval against the codes actually in play, technique questions answered in writing, examination setting and grading against the qualification calendar, written practice updates when a scheme edition or a contract changes, control of technique demonstrations on representative geometry, and audit attendance. Where a specific report is challenged rather than the programme, an independent technical review sits alongside — the same discipline applied to output, covered under NDT report validation.
The rhythm is lumpy rather than light. Qualification cycles, contract wins and audits cluster together, and between clusters demand collapses to almost nothing. That shape — continuously required, intermittently occupied — is the entire economic argument for the arrangement, and it is why the comparison against hiring turns on qualification frequency rather than on how many technicians are on the payroll.
The four signatures an auditor traces
An auditor does not assess your Level III. The auditor picks a technician's certificate and walks backwards through four signatures, stopping at the first one that is missing, unsigned, out of method scope or out of date. Written practice approval. Procedure approval. Examination approval and grading. The qualification recommendation sitting behind the certificate itself. Every other question in the audit is downstream of those four, and most audits never get past them.
SNT-TC-1A anchors the first and the third: the employer prepares a written practice that is on file and approved by the employer's Level III, and the Level III carries responsibility for approving and grading the examinations administered for certification. ASME Section V Article 1 T-150 anchors the second, requiring written procedures and requiring a revised procedure to be prepared and approved by a Level III when an essential variable changes. Written practice development covers the document at the top of the chain.
The fourth signature is the one firms get wrong. An outside Level III recommends qualification — attests that training hours, documented experience and examination results satisfy the written practice. The employer then issues the certificate. Those are two separate acts by two separate parties, and putting the consultant's name where the employer's belongs creates a finding rather than closing one. The distinction survives every regime; only the terminology moves.
Method scope: the limit on every signature
Every one of those signatures is bounded by method. Certification is granted method by method, so a Level III certified in UT and PT approves UT and PT procedures and grades UT and PT examinations, and cannot reach RT, ET, MT or VT with the same signature. Seniority does not extend scope. Neither does thirty years of experience, a second regime, or a client's willingness to accept it at the time.
This is where arrangements decay without anyone noticing. A firm engages a Level III covering the four methods it sold at the time. Eighteen months later it wins work in a fifth method, writes a procedure, and files it under a signature that does not cover it. The programme now carries a documented gap that will surface at the next audit, dated precisely to the day that procedure was approved — which is worse than a gap nobody can date.
Two controls prevent it. First, the scope statement lists the methods covered, the regime each was certified under, and the certification expiry: ASNT NDT Level III certifications renew on a five-year cycle, either by documented recertification points or by re-examination. Second, adding a method triggers a scope review before the first procedure is written, not after the first job is sold. Coverage gaps are closed by adding a second Level III, never by stretching one.
Three ways cover is structured
Retained cover names a Level III of record continuously in your written practice. It fits firms whose contracts require a named Level III at all times and whose demand is steady but low — procedure approvals as work changes, examinations on a calendar, a written practice review each year, an audit when a client calls one. What you are buying is availability and continuity of authority rather than a volume of hours.
Project cover attaches to a defined scope and ends with it: a single contract, one facility, a method addition, a procedure set built for one client's specification. It suits EPCs, fabricators and firms taking on work outside their normal envelope for a fixed period. The record it leaves behind is narrower, which is entirely acceptable as long as the written practice states clearly which work the arrangement covered and on what date it ended.
Interim cover fills a hole that already exists — a resignation, a long absence, an acquisition that moved the Level III to another legal entity. It is time-boxed against recruitment and judged by what it leaves behind: a handover pack containing examination banks, procedure revision history, demonstration records and the reasoning behind non-obvious technique calls. Interim NDT Level 3 cover sets out how quickly the gap closes and what closes with it.
What the arrangement cannot do
The arrangement cannot issue your certificates. Under SNT-TC-1A certification is an act of the employer and does not transfer to an agency, however complete the agency's technical work. It cannot hold your records — training hours, documented experience, examination papers and vision test results all live with you and are produced by you at audit. It cannot run your vision examinations; it specifies the requirement, and you arrange, witness and retain the test.
It cannot supervise daily field work. A Level III of record is an approval authority, not a site supervisor, and a programme leaning on the arrangement for day-to-day technical direction has a resourcing problem dressed up as a compliance solution. Nor does a designated Responsible Level 3 by itself close the record-based findings that generate most audit results — vision currency, on-the-job training documentation and retained examination papers stay with the employer regardless.
Most importantly, it cannot retroactively create history. Where training hours were never recorded, experience was never documented, or examination papers were discarded during an office move, no signature reconstructs them. The fix is requalifying people who are almost certainly competent, which costs time, money and morale in that order. That is the argument for putting the arrangement in place before an audit is announced rather than in the six weeks after.
What your firm must still own
Six things stay yours no matter how complete the outside cover is. Adoption of the written practice as your document, not the consultant's. Training and on-the-job experience records for every technician. Near-vision and colour-contrast examination currency. Retained examination papers, scores, dates and invigilation records. The signed certificates themselves. And the recertification decision — SNT-TC-1A recommends a maximum five-year interval across Levels I, II and III — together with records retention behind all of it.
None of those is technically difficult. All of them are administratively fragile, because each depends on somebody maintaining a filing discipline between events that are months apart. The failure pattern is uniform across firm sizes: the technical work is excellent, and the evidence that it happened is scattered across three laptops, a shared drive nobody has mapped, and the inbox of an employee who left last year.
Build the record structure first and the outside arrangement becomes cheap to run. A single register holding, per technician per method, the training hours, experience dates, examination results, vision test date and current certificate revision answers most audit questions from one screen. It also converts the annual written practice review from a week of archaeology into an hour of reading, which is where the arrangement stops feeling like overhead.
How this differs from a project consulting engagement
This role is not the same purchase as a consulting project, and conflating the two causes the most common disappointment in the market. A project engagement is scoped to an artefact and ends: a procedure set delivered, a written practice authored, a programme gap assessment closed out, a fitness-for-service assessment signed. Success is the artefact existing and being defensible. The full consulting practice catalogue lists those engagements and what each produces.
Level III cover is scoped to an authority and continues. Success is that a signature exists on the day it is needed, in the right method, from a person whose certification is current and whose name appears in your written practice. It is closer to a named-officer arrangement than to a piece of work, and it is evaluated on continuity rather than on deliverables. The wider service description sits under ASNT Level III consulting services.
The practical difference shows up in how the two are governed. A project is governed by a deliverable and a date. Cover is governed by response time, method scope and continuity — what happens when the named person is unavailable, how a second Level III is named, how quickly a procedure is turned around when a client changes acceptance criteria mid-job. Ask those three questions before signing rather than discovering the answers during a shutdown.
What an auditor asks for, in order
Audits run in a predictable order, and preparing in that order beats preparing exhaustively. The auditor asks for the written practice first, checks its edition against the scheme currently in force, and checks its approval signature against a current Level III certification in the relevant methods. Second, a technician's certificate — chosen by the auditor, not offered by you. Third, the entire evidence chain sitting behind that one certificate.
That chain is training records, documented experience, examination papers and grading, vision test currency, and the qualification recommendation. Fourth comes the procedure covering the job that technician actually performed, and whether the revision in force at the time matches what was done. Fifth, the demonstration record where the referencing code required one. Findings almost never come from the first two steps — they come from steps three and four, where the paper trail thins.
Running that sequence against yourself before an auditor does is the entire content of a gap assessment, and the value sits in the lead times rather than in the findings themselves. A missing vision test is a same-week fix. A missing examination paper is a requalification with a technician off the tools. Programme audit and gap assessment covers the review and the closure work that follows it.
When outsourcing stops being the right answer
Outsourcing stops being right when the workload stops being lumpy. A firm running continuous qualification, frequent method additions, multiple concurrent client schemes and permanent audit exposure needs the authority resident rather than scheduled. At that point the arrangement becomes a bottleneck instead of a saving, and the tell is unmistakable: a standing queue of procedures waiting on a signature, and field crews working to drafts.
The comparison is a frequency question, not a headcount question. Count qualification events, procedure revisions and audits per year rather than technicians on the payroll — a forty-person crew in one method generates less Level III demand than a twelve-person crew across five. Published US salary bands are worth reading against that count; NDT Level 3 salary ranges sets out what the market pays, because the honest comparison is total annual demand against a full-time cost.
There is a hybrid that works well for firms in between: a resident Level II or quality engineer who owns the records, the calendar and the routine field questions, with an outside Level III holding the signatures and the technical authority. It keeps administration close to the work and authority with certification, which is the split that actually survives an audit. Describe your situation and we will tell you which of the three you are — including when the answer is that you should hire.
What does an outsourced Level III do in a working month?
Reviews and approves procedures against the codes in play, answers technique questions from the field, sets and grades qualification examinations as the calendar requires, updates the written practice when a scheme or contract changes, controls technique demonstrations on representative geometry, and attends audits to defend the programme. Between those events the work is small, which is exactly why the role is outsourced.
Which four signatures does an auditor trace?
Written practice approval, procedure approval, examination approval and grading, and the qualification recommendation behind each certificate. An auditor follows a technician's certificate backwards through those four and stops at the first gap. Two further records, the certificate itself and the near-vision and colour-contrast examination, never carry an outside name and remain the employer's to produce.
How does method scope limit the arrangement?
Certification is granted per method, so an outside Level III can only sign inside the methods held. A UT and PT Level III cannot approve an RT procedure or grade an RT examination. Before signing anything, the scope statement must list the methods covered and the regime under which they were certified. Gaps are covered by adding a second Level III, not by stretching one.
What are the three ways cover is structured?
Retained cover names a Level III of record continuously, sized to your qualification calendar. Project cover attaches to a single scope, contract or procedure set and ends with it. Interim cover fills a gap after a resignation, illness or acquisition and is time-boxed against recruitment, with a handover pack built from day one so the replacement inherits a working programme.
What can the arrangement not do?
It cannot issue your certificates, hold your records, run your vision examinations, supervise daily field work, or make your programme compliant by signature alone. It also cannot fix a programme whose training hours, documented experience or examination papers were never recorded. Missing history is rebuilt by requalifying people, and no outside signature substitutes for that.
What must the firm still own itself?
Adoption of the written practice, training and on-the-job experience records, near-vision and colour-contrast examination currency, retained examination papers and scores, the signed certificates, the recertification decision on a maximum five-year cycle under SNT-TC-1A, and records retention. Those six are what an auditor asks the employer to produce, and none of them can be outsourced.
Frequently asked
Can an outsourced Level III sign our written practice?
Yes, and it is one of the main reasons firms engage one. SNT-TC-1A requires the written practice to be on file and approved by the employer's Level III, and an outside agency Level III designated in that document satisfies the requirement. An auditor checks two things: that the person holds current certification in the relevant methods, and that the involvement is genuine and documented rather than a name on a cover sheet.
Our Level III just resigned — what stops immediately?
Existing certifications remain valid, but the approving authority is gone. 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 until the first procedure change or the first new hire, then it halts. Interim cover closes the gap while recruitment runs and builds the handover pack the permanent appointment inherits, so the same cliff does not reappear.
Which methods can be covered?
UT, RT, MT, PT, VT and ET, plus advanced techniques including phased array and TOFD. Certification is granted per method, so every scope statement names the specific methods covered and the regime under which each was certified. Where a programme spans more methods than one Level III holds, the gap is filled by naming a second Level III for those methods rather than by extending an existing signature beyond its scope.
Is outsourcing cheaper than hiring a Level III?
That turns on qualification frequency, not headcount. Count procedure revisions, qualification events and audits per year. A firm with steady, low demand pays for availability it uses in bursts; a firm with continuous qualification and multiple client schemes needs the authority resident. Published US salary bands for the role give the honest denominator — compare total annual demand against a full-time cost, not one day of either against the other.
Does a designated Responsible Level 3 close a Nadcap audit?
It satisfies the personnel-authority requirement under NAS 410, which AC7114 assesses, and NAS 410 permits an outside agency Level 3 to hold that designation when the employer identifies them in writing. It does not by itself close the record-based findings that generate most Nadcap results — vision test currency, on-the-job training documentation and retained examination papers stay with the employer and are produced by the employer.
ASNT Level III consulting engagements
Level III work is not one service. The five engagements below are bought for different reasons, by different people, and produce different deliverables. Each is set out separately so you can see which one fits before you contact us. All are delivered by Atlantis NDT founder Anoop Rayavarapu, ASNT NDT Level III.
- Outsourced Level III and Level III of record
- Written-practice development
- Procedure approval and review
- Audit support (customer and ISO-style audits)
- Temporary and retainer Level III coverage
Outsourced Level III and Level III of record
Who it is for
Companies that certify NDT personnel under their own written practice but do not employ a Level III, or whose Level III has left. Typical buyers are small and mid-sized inspection companies, fabricators with in-house NDT, and firms that have won a contract requiring a named Level III.
Deliverables
- A named ASNT NDT Level III designated in your written practice for the agreed methods.
- Approval of procedures and technique sheets within that method scope.
- Administration and grading of Level I and II examinations, and certification recommendations under your practice.
- Technical answers to your technicians and clients on the covered methods.
- A written record of every approval and decision, kept with your quality records.
How the engagement runs
- Scope call to agree methods, sites and the volume of approvals expected.
- Review of your current written practice, procedures and certification files.
- Designation letter and any written-practice changes needed to name the Level III.
- Ongoing approvals, examinations and technical support under the agreed terms.
Can an outside Level III be named in our written practice?
Yes. SNT-TC-1A allows an employer to use an outside agency Level III; the written practice must say so and define the arrangement.
Which methods can be covered?
The methods the Level III holds certification in. Confirm your methods in the enquiry and we will state what can be covered.
Written-practice development
Who it is for
Employers that need a new written practice, a practice revised to the current SNT-TC-1A or CP-189 edition, or a practice that matches what the company actually does after an audit finding.
Deliverables
- A written practice covering training, experience, examinations, vision requirements, certification, recertification and records for your methods and levels.
- Examination and record templates aligned to the practice.
- A change summary if an existing practice is being revised.
- Level III approval and a handover session with the person who will administer it.
How the engagement runs
- Gap review of your current practice, customer specifications and certification records.
- Draft practice issued for your review.
- Revisions, approval and issue.
- Handover and, if needed, transition of existing certifications to the new practice.
Where is the full written-practice service described?
See NDT written practice development for the section-by-section content and the common audit findings.
Can one practice cover SNT-TC-1A and CP-189 clients?
It can be structured to meet both where the requirements are compatible, with the differences stated. We confirm this against your client specifications.
Procedure approval and review
Who it is for
Inspection companies and fabricators with procedures that need Level III approval, owner-users who want a contractor's procedure independently reviewed, and teams whose client has rejected a procedure.
Deliverables
- Review comments against the governing code, the method standard and the client specification.
- A revised procedure or specific redlines, and technique sheets where needed.
- Level III approval, or a clear statement of what prevents approval.
- Where required, a demonstration plan for qualifying the procedure.
How the engagement runs
- Send the procedure, the governing code and the client specification.
- Review and comments returned in writing.
- Revision and re-review until the procedure meets the requirements.
- Approval and issue, with a demonstration if the specification requires one.
Do you also qualify procedures by demonstration?
Yes. See procedure qualification and demonstration for how demonstrations are planned and recorded.
Will you approve a procedure you did not write?
Yes, if it meets the code and specification after review. If it does not, we say what must change.
Audit support (customer and ISO-style audits)
Who it is for
Companies facing a customer audit, a prime contractor's supplier audit, or an internal or ISO 9001-style quality audit of their NDT programme, and companies closing findings from one.
Deliverables
- A pre-audit gap review sampling records the way an auditor will: from a field record back to the technician, procedure, equipment and written practice.
- A prioritised list of gaps with the fix for each.
- Technical support during the audit on NDT questions.
- Help writing corrective actions for NDT findings, and verification that they are closed.
How the engagement runs
- Agree the audit type, date and the auditor's likely scope.
- Gap review and findings list.
- Remediation support before the audit.
- Audit-day support and close-out of any findings.
Do you provide accreditation or certification-body audits?
No. We support your NDT programme through customer and quality-system audits; we are not an accreditation or certification body.
How early should we start before an audit?
As early as possible. Some gaps, such as missing experience records or procedures needing requalification, take time to close properly.
Temporary and retainer Level III coverage
Who it is for
Companies whose Level III is on leave, has resigned, or is overloaded, and companies that need Level III access for a project or a peak period rather than permanently.
Deliverables
- Level III coverage for a defined period or project, for the agreed methods.
- Approvals, examinations and technical decisions during that period, each recorded.
- A handover note at the end of the period listing open items.
- Where a retainer suits better, an agreed scope of support over an ongoing term.
How the engagement runs
- Agree the period, methods and the expected workload.
- Short review of the current practice and open items.
- Coverage begins under the written practice.
- Handover at the end of the period, or review of the retainer scope at agreed intervals.
What stops when our Level III leaves?
Anything the written practice reserves to the Level III, such as procedure approval and certification decisions, until another Level III is designated. Temporary coverage keeps those moving.
Is a retainer or per-task arrangement better?
It depends on how steady your volume of approvals and examinations is. We will suggest the arrangement that fits once we know the workload.
