Verify the NDT Examiner’s Credential and Employer Link Before Relying on the Report

Verify the NDT Examiner’s Credential and Employer Link Before Relying on the Report

A technician’s wallet card, training certificate or report signature does not by itself establish that the person was qualified to perform the stated examination for the employer that issued the report. First identify the qualification scheme invoked by the order or report. Then verify the chain from the named examiner to the scheme issuer, method and technique scope, current status, employer authorization and report responsibility.

A missing record is not proof that the examiner is unqualified or that the report is invalid. It is an unresolved link that the report provider or employer should clarify before the buyer relies on the result.

Start with the invoked scheme

NDT personnel qualification can be organized in different ways. The issuer and the employer relationship matter because they determine what a supplied credential does—and does not—show.

Under ASNT SNT-TC-1A, personnel certification is employer based. ASNT’s June 11, 2026 advisory says SNT-TC-1A is a recommended practice that guides employers in establishing their own written practice for qualifying and certifying personnel. It is not a centralized, independent or third-party certification scheme. Under that model, the employer issues certification within its own written practice and is responsible for the evidence supporting it.

A training provider may deliver training and may provide certification examinations under an employer’s written practice. Training completion alone is not employer-based certification. ASNT specifically states that training organizations cannot independently issue SNT-TC-1A certifications, even when a certificate carries the signature of an ASNT NDT Level III professional or uses ASNT branding.

ASNT 9712 is a different programme. ASNT presents its 9712 Level II credential as an independently issued certification programme aligned with ISO 9712:2021 and ANSI/ASNT CP-9712:2023. Its practical examination options distinguish methods and techniques, including ultrasonic testing of castings and forgings versus welds. A central credential still has to be checked for the named person, current status, method, level and applicable technique. It does not let a buyer assume coverage from the word “Level II” alone.

Audit the examiner credential chain

Use the report signature as the starting point. Work forward through the evidence instead of starting with a laboratory logo or a training certificate.

Link in the chain What to verify What does not complete the link
Named examiner The full name or internally controlled personnel identity matches the report A generic laboratory stamp or an unsigned report
Invoked scheme Whether the report or contract calls for an employer-based system, third-party scheme or another named basis Assuming every report uses ISO 9712 or SNT-TC-1A
Issuer The organization that issued the credential or employer certification under the invoked scheme A training provider’s course-completion certificate
Method, level and technique The credential or employer record covers the named NDT method, level and relevant technique or product scope A general “NDT certified” statement
Current validity The credential is current under the relevant scheme and any contract requirements The issue date alone
Employer link For employer-based certification, written-practice and employer-issued evidence connect the person to the report provider and assigned work A Level III signature without employer linkage
Report responsibility The report identifies who performed, interpreted or accepted the work under the applicable system A personal card with no connection to the report

Keep personal credential numbers, addresses and other sensitive documents in the buyer’s controlled quality file. A public copy of a report review should state only whether the required evidence was verified, missing, expired, conflicting or not applicable.

Training is not the same as certification

Training records can be essential inputs to qualification, but they prove a narrower fact: that someone completed a course or training activity. They do not prove the employer’s authorization, the applicable method and technique, current validity or authority to issue a report.

ASNT’s 9712 application guidance illustrates the distinction. It accepts training documentation as evidence of completed training, while identifying separate experience documentation and examination requirements for certification. It also distinguishes qualifications from training certificates in the documents accepted for an application. This supports a practical buyer rule: keep training, personal certification and employer authorization as separate fields in the evidence record.

If the report uses an employer-based qualification system, request the provider’s confirmation that the examiner was qualified and authorized under its current written practice for the stated method and work. You do not need the provider to disclose its entire written practice. You do need a traceable statement that links the examiner, employer, method, level or role, report and applicable procedure.

Keep laboratory accreditation separate

Laboratory or inspection-body accreditation concerns an organization and a stated scope of activities. It is not an individual technician credential. A laboratory may have an accreditation logo while the buyer still needs to verify the named examiner’s role and personnel basis for a particular report. Conversely, a person may hold a valid third-party credential while the organization’s applicable scope or report controls remain unresolved.

For the organization-level task, see how to verify a test report with the laboratory that issued it and how to check a calibration certificate and the laboratory’s scope. Those checks help establish issuer identity and organizational scope. They do not replace the examiner credential chain.

Record the open link, then request it

For each NDT report, record one of these outcomes:

  • Credential and employer link confirmed: The named examiner, invoked scheme, issuer, method and scope, current status, employer authorization where required, and report responsibility are traceable.

  • Credential confirmed; employer link unresolved: A personal credential is present, but the evidence does not show that the employer authorized the person for this assigned examination.

  • Training evidence only: A course or training certificate is available, but certification or authorization evidence is missing.

  • Organizational scope confirmed; personnel basis unresolved: The laboratory or inspection body is identified, but the report does not establish the named examiner’s qualification basis.

  • Scheme or scope unresolved: The report does not identify the qualification route, applicable method, technique or responsible employer.

Send a focused request to the report provider: identify the invoked qualification scheme; confirm the named examiner’s current method, level and applicable technique or product scope; and, for employer-based systems, confirm qualification and authorization under the employer’s written practice for the specific report. Retain the answer with the report.

For an item-specific inquiry, KTSU’s excavator undercarriage parts collection provides the public product family. Request the actual report and the available personnel-basis record for the quoted item. KTSU is not represented here as employing ASNT- or ISO-qualified personnel. The buyer’s review is complete when the examiner’s credential and employer link are traceable under the invoked scheme, or when the missing link is clearly recorded for the responsible provider to resolve.
