I know the FAA well as I always have to wait for my permanent Certs to come after checkrides, so I am very patient with them now :bandit:. I just didnt know how it works since I was a OTS applicant using ASAP.

If it helps at all, I know that it works somewhat like this:
After they're ready (HAHA!), they will post on the MAIN page on ASAP declaring that you have been authorized to take the AT-SAT.
Then, a few days to a few weeks pass, as each group (separated by which testing site you'd take your AT-SAT at) gets notified of the specific testing timeframe that they can schedule in. Then, Robinson Aviation (the FAA's contractor, and who is in-charge of all things AT-SAT) will contact you, or you have to contact them (someone else please verify) within a certain timeframe, to schedule your precise time/date.
After you take your AT-SAT, the scores will also be on ASAP after a few days. There's more to the process involving ASAP after that, but this should give you a beginning idea.
