It was a general problem as far as I can see. There was a notice placed on the website last year promising that the backlog was going to be cleared by the end of 2011. That has now been removed and they still have backlog of more than 1000 applicants spanning 51 pages according to their status update page on the website http://alliancept.org/pdfs/credentia...tus_update.pdf
As I said above, for some reason the Alliance has created a bottleneck in the credentialing process which is now causing this huge problem for applicants. What's more annoying is that they are still displaying this 14-20 weeks on their forms and correspondence with applicants. The whole process is quite frustrating really.
