Passport photo instructions

If you will be registering with NDTCB for the first time, you must provide two passport photographs with a completed Photograph Verification Form, signed by your employer or by a professional individual as listed on the form. The passport photos must:

• measure 5 cm wide X 7 cm high (2 inches wide X 2-3/4 inches high)

• be clear, sharp, in focus, and in full colour
• be taken straight on with the face and shoulders centered and squared to the camera
• reflect your current appearance (taken within the last twelve (12) months)
• show your complete name, as well as the name and complete address of the photo studio and the date the photo was taken on the back of one photo
• be submitted, via mail or courier

Self-taken and/or self-printed photographs and non-passport photographs will not be accepted. We may request additional photographs at any time if we deem previously submitted photographs unacceptable.

Identification instructions

Please submit verified true copies of two (2) valid pieces of Canadian Government recognized identity documents on a completed Identification Verification Form, signed by your employer or by a professional individual as listed on the form. Examples of acceptable proof of ID are a passport, driver’s license, military identification, certificate of Indian Status, or a provincial or territorial health card that includes your photo and signature (excluding Alberta, Manitoba, and Newfoundland and Labrador).

• One of these documents must have the applicants’ full legal name, date of birth, photo & signature.
• If you have already applied to the NDTCB for NDT or X-Ray Fluorescence (XRF) analyzer operator certification and have submitted one of these documents, then you only need to submit one (1) piece of ID.
• Documents in a language other than English or French must be translated.
