International Assessments

Assessments Requirements Overview

Applicants requesting certification as a Commercial Surface Supplied Diver under the Diver Certification Board of Canada (DCBC) scheme will have to undergo an assessment to determine whether they meet the enabling objectives of the Canadian Standards Association CSA Z275.4, Competency Standard for Diving Operations.

The Association of Diving Contractors International (ADCI) currently offers U.S.-based certification. Working divers without ADCI certifications may also contact us for assistance if an assessment is required.

The assessment is a two-part process:

  •  initial review of an applicant’s current qualifications (certs, dive logs, documented work experience), and
  • observed, practical assessment in which any missing enabling objectives are completed and the applicant’s competency is tested in both diving related theory, and practical demonstration of commercial practices and underwater skills (observed dive).

International Assessments
The initial assessment encompasses a comprehensive, detailed look at the applicant’s formal commercial dive training, current certifications, work history, commercial log books, and medical fitness to dive. The results of this will determine eligibility as well as identifying areas not in compliance with the CSA Commercial Diver Competency Standards or ADCI Consensus Standards. Enabling Objectives not met during the initial screening process will have to be completed prior to applying for the diving certification. A detailed training schedule and cost will be provided upon request.

At completion of the final assessment, a letter is sent to you (the applicant), which you include with your application to the certifying agency (Diver Certification Board of Canada or Association of Diving Contractors, International). The final assessment letter documents that  you have completed an assessment and have met all requirements for Certification to the level you have applied for in accordance with the CSA Z275.4 and CSA Z275.5  or ADCI Standards. You send in your application directly to DCBC or ADCI along with the required fees. The applications can be downloaded from their respective websites at ADCI  or DCBC.

DIT will maintain a file with a copy of your application documentation for periodic review and audit by the Diver Certification Board of Canada and the Association of Diving Contractors International.
