Working divers — verified before enrolment

The ITDA Occupational Diving qualifications are open to divers with the right background, not to everyone. Every one of the 15 qualifications has its own entry requirement, and each is enrolled separately.

Submit an experience & qualification check for the discipline you work in — once approved, enrolment on that qualification is unlocked.

1. Submit your experience check

Tell us the qualification you are applying for, the certification you hold and your logged experience — once per qualification.

2. ITDA HQ verifies it

HQ reviews your certification, agency, dive experience and medical against the entry requirement for that qualification.

3. Enrolment opens

Once the check is approved, enrolment on that qualification is unlocked for your account.

The qualifications

Each qualification is enrolled separately and states the experience required before you apply. Submitting a check for one does not unlock the others.
