Refer to the table below to check your equivalent SAA Diver grade.

Qualified divers from other agencies are welcome to join the SAA and cross over to our training structure is easy to do.

* equates to CMAS 1* until 10 additional qualifying dives done.

This guide gives the highest permitted cross-over level. Each Club Diving Oficer reservers the right to assess each application on experience as well as qualifications held and my cross qualifications over at a lower level.

Nothing in this guide alters the policy that Diving Officers may not award certification higher than that held by them.

Grades above SAA Dive Supervisor may only be awarded by the National Diving Officer.


We welcome Instructors trained by other agencies exactly as we welcome divers. The difference is that all Instructor cross overs are done centrally by the National Diving Officer.

All that is asked is that you meet the same criteria as SAA Instructors need for the relevant Instructor grade. This means holding the appropriate SAA diver grade (crossed over by the Club Diving Officer or National Diving Officer) and any other criteria such as holding any necessary SAA qualifications.  Your new Club or Region will assist in this process and advice is always available from Head Office or the National Diving Officer – Use the Contact us page to get in touch with either of them.
