That is one more typical example for the CMAS federations. Every national federation does whatever it wants. And even among themselves they are discordant.:cussing:
PADI DM as well as CMAS 3* are certified as Dive Leader according DIN EN 14153-3 and ISO 24801-3 and they are equivalent in nearly every equivalency list you will find, i.e.
Tauchschein
But even this DIN is misleading in that its for the teaching of recreational SCUBA by commercial organisations, e.g PADI Etc. Not the recreational standard of the diver by national federations, e.g SAA for the UK.
CMAS was a all about equivalence before they started teaching SCUBA themselves, now there pretty meaningless.
To the OP, I think you will find the ASE people will require someone with this equivalence.
