Maybe I'm just ignorant and out of line here, but I had never heard of IDEA either so I looked for them. They are a member of WRSTC, like PADI and others, but finding anything on them other than on wikipedia is hard (seemingly an old organization going back to 1952) -- their website domain has expired. There is phone and street address contact info on the WRSTC website, but I did not try to contact them. That is probably where I would start, if I were you. On the other hand, if you have an instructor that does not give you the standards and the agency does not keep up its website (very odd in today's world), I have to wonder about its future. Do you want to invest further training time in them? You might be better served switching now to PADI, NAUI, SSI or another agency with a little more transparency (and a clearer future?). My 2 cents.
