This article has deteriorated into a list of names and weblinks of any organisation that offers dive training, and Wikipedia is not a directory. The selection criteria for this list is simply too imprecise to keep out spammers and the list no longer has encyclopedic value. RexxS ( talk) 22:55, 6 April 2013 (UTC) reply
And it's simply a matter of style choice that the title does not include "notable" as a limitation; the omission of that does not legally bind us to literally include all training organizations that exist. See Wikipedia:Manual of Style/Lists#List naming: "[T]he precise inclusion criterion of the list should be spelled out in the lead section (see below), not the title. For instance, words like 'complete,' 'famous' and 'notable' are normally excluded from list titles. Instead, the lead makes clear whether the list is complete, or is limited to famous or notable members (i.e., those that merit articles)." postdlf ( talk) 16:30, 7 April 2013 (UTC) reply
I've also already addressed above the incorrect notion that this list is somehow obligated to include the "thousands" of such organizations, just because they exist; the truth is that we can limit it to only organizations that merit articles and we do this routinely with lists. Whether you want this list to include "training organizations", as it and its corresponding category presently do, or "certifying organizations" is a separate issue and not an AFD concern, one you can deal with through normal editing and discussion).
I also don't know where you got the idea that the list cannot have the same inclusion criteria as the category; WP:CLN tells us the exact opposite, that they are complementary methods of organization. We could decide that a list and a category of the same name have different selection criteria, if we see some value in including non-notable entries for example, or we could decide that a list be limited to notable entries only and so have only the articles that go in the corresponding category. postdlf ( talk) 15:43, 8 April 2013 (UTC) reply
"This page lists SCUBA diver training organizations". The article on diver training states
"Competent diving instructors may work independently or through a university, a dive club, a dive school or a dive shop. They will offer courses that meet, or exceed, the standards of the certification organization that they work with. Many dive shops in popular holiday locations offer courses that try to teach you to dive in a few days, and can be combined with your vacation". So yes, universities, dive clubs, dive schools and dive shops may be diver training organisations, and tens of thousands of them are eligible for this article as it stands. As you already know, subjects that are not notable are just as acceptable as entries in lists, which is why we don't use "Has a Wikipedia article" as the inclusion criterion. In any case, this article already has masses of entries that fit the current selection criteria (and potentially many thousands more). If you want to change the selection criteria to something useful (and "Has a Wikipedia article" isn't - because of the Western ethnocentric bias in en-wp), then please tell us how to trim the current list to fit your new criteria for "List of diver training organizations" at the same time. If it was that easy, it would have been done by now. -- RexxS ( talk) 22:59, 8 April 2013 (UTC) reply
