Frequently Asked Questions

What is IDSA's primary role?
IDSA is an independent, non-governmental organisation that sets international standards for commercial diver training. We audit and accredit member schools to ensure these standards are met, promoting safety and quality across the industry.
What is the difference between a Full Member and an Associate Member?
A 'Full Member' is a training school that has successfully undergone a rigorous audit and demonstrated full compliance with IDSA's training standards. An 'Associate Member' is a school that is actively working towards implementing these standards to achieve full membership.
How can I verify a diver's qualification?
You can instantly check the validity of an IDSA Qualification Card (Q-card) using our public online register. You will need the certificate number and the holder's date of birth. For cards issued before 2016, manual verification may be required.
