Be water, be extended

Taken from the official AIDA International course standards, last checked 23 Oct 2026. The numbers are minimums, not the whole assessment — technique, safety awareness and buddying are judged too.

Congratulations on deciding to take A3 and go looking for a better version of yourself. Every metre is unknown territory, but once you have been there, you stop being afraid of it. It is a little like learning to ride a bike, or learning to swim — once you have reached a depth, the fear goes. What is left is missing it.
