Not all the qualifications from other training agencies are as easy to match to a BSAC equivalent.


Matching instructor qualifications between agencies is more complicated. With safety our paramount concern, your level of experience is often more important than your dive qualification.

In all cases the final descision on anyone’s fitness to dive rests with the Branch Diving Officer. If your qualification is not shown here, please refer to the BSAC equivalent qualificatons.
