I can see why you are having trouble finding an answer.
There is a listing of this organization on the IDEA site. However there are no reviews and the links to a web site do not take you to the web site. The address listed does not include the state, just a city (it is located in Texas). There are prices listed for both group fit and personal training certifications.
The organization does not appear to be or have been NCCA accredited.
There is a web site for a company called PFIT, that appears to be a small business run by a couple whose name begins with the letters pf, which is kind of catchy, but there is nothing on the site to link to professional training.
There is a facebook page, and I found one person posting over and over asking for information on how to renew her certification. There is a posting in a small block on the side telling people they can renew through ISCA, which will honor PFIT initial certifications. Which makes it seem as though they are not offering the certification any more.
I looked at the page for ISCA and do not see that they say they are NCCA accredited either (at least on the home page of their site). I also did not find them in the comparison tools that both IDEA and ACE offer to allow you to compare major certifications for what they cover, what they cost, how the exams are proctored, etc. However I am in no way an expert on what certifications are most accepted where, and would suggest you look to see what credentials will provide you with the work you most want.
Given that you are going to have to pay to recert anyway you could see what it would cost to do it through ISCA, and compare that to other options and see what works best for you.
Some years ago I hired a contractor to do some work in my basement. over 5 or 8 years some of it fell apart, some of it had to be ripped out as it was not code. I have since found and developed a relationship with someone who is not cheap, but whose credentials are as impeccable as is his work. So I think the moral of the story is that it is worth while to certify through an organization that has been around for a fair amount of time, and that is nationally recognized.
