Revalidating Your NDT Certification

When an NDT certification that you hold becomes invalid, there are specific processes that you must follow to revalidate it.

Guidelines for revalidation

1. When your NDT certification has been invalidated due to a significant interruption in NDT work experience or a lapse in certification validity a year or more after its expiry date, you must successfully pass the applicable recertification examination(s).
2. When your NDT certification has been invalidated due to not meeting the requirements of the visual acuity test:
   • You must undergo another visual acuity test, performed by an independent third party (non-employer) medically recognized personnel, and meet the requirements outlined on the Vision Test Report Form for Non-Destructive Testing Personnel (PDF, 2 Mb)
3. When your NDT certification has been invalidated at the NRCan NDTCB’s discretion because you committed a code of conduct violation, or for some other reason, the conditions and procedures for revalidation will be determined by the NRCan NDTCB’s Special Review Committee on a case-by-case basis.
