Aqua instructor here. Not clear what the question is. Perhaps repost? Thanks. Certainly not all certifications in this avenue are created equally.
Hello Vernon Smith,
Thank you for asking; here is a link with sources which I hope are helpful for you:

Your best bet would be to call IDEA directly, or to google Aqua certifications and call one of those agencies. The site you posted on (IDEA) isn’t a certifying body.
There are a lot of aqua-certified instructors on this board. If you have a question about aqua fitness, they may be able to answer you.
