Effective November 1st, 2017, the EDO written examination is available in an updated electronic format only. The multiple-choice examination is only available to write at an expanded set of EDO Examination Centres and other participating examination centres. Candidates who have been approved for the written examination may register for the electronic examination. For more information on eligibility and registration for the electronic examination, please contact the NRCan NDTCB and read additional information below.
If your first examination attempt is not successful, you are permitted two re-examination attempts. You should ensure there is a period of 30 days between attempts. If you are not successful after a total of three (3) attempts, you must repeat the vocational training program and submit proof of its completion to the Natural Resources Canada (NRCan) Non-Destructive Testing Certification Body (NDTCB) before you can attempt another re-examination.
How to apply
To apply for re-examination, you must submit a completed page 1 of the Application Form for Exposure Device Operator Examination (PDF, 692 kb) to the NDTCB by mail, fax or e-mail. Ensure that you select “re-examination” on the application form and include payment.
Passport photos and copies of government issued ID are not needed to apply for an exposure device operator (EDO) written re-examination.
To protect your payment information, do not send credit card information by email. If you are paying by credit card (Visa, MasterCard or American express), submit your application via fax or email only. If you have any questions, please call 1-866-858-0473.
