How do you quantify a agency?
Agency:
: a business that provides a particular service (i.e. diver training, or cave diver training)
In this context, the above definition suffices. There's no need for quantification of basic English terms that exist in the dictionary.
What is your definition on "agencies of note"?
The word 'Leading' is suitable for what I had in mind...
Leading:
: having great importance, influence, or success
: most important
: coming or ranking first / foremost
: exercising leadership
: providing direction or guidance
That said, specifically in relation to "agencies of note", the word noteworthy might be relevant:
Noteworthy:
: worthy of or attracting attention especially because of some special excellence
So, for the purposes of discussion, a 'cave agency of note' might be defined by;
" A diving training agency exercising leadership in cave diving... and/or worthy of; or attracting attention especially because of, some special excellence in the field of cave diving training ".
Another way to look at is - is whether cave diving is the foremost, or primary focus of the agency concerned. Or, to what degree cave-specific tuition features in their overall prospectus of training courses.
