International Assessments


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 assessment is a two-part process:

  • Applicant’s current qualifications (certs, dive logs, documented work experience) are reviewed for alignment with requirements
  • Observed, practical assessments are conducted to complete any missing objectives and to test the applicant’s competency in both diving related theory and practical demonstration of commercial practices and underwater skills (observed dive)
