Seeing available NCLEX test dates without ATT?

I don't think so. I wasn't able to.

No it's not possible. The times change regularly throughout the day

I don't think so. You might ask your friends who already have ATT and paid for NCLEX to look it up for you.

Whatever appointments are available today will not be available tomorrow. Appointments scheduled may be cancelled. There's a reason you cannot have calendar access until you have an ATT: it doesn't matter AT ALL before then.

I guess I should have said this is my original post or asked this question instead: I'm not interested in seeing specific times, I'm just wondering how soon after getting my ATT will I be able to test?

It literally varies from hour to hour. When I register earliest date was 4 days away, 2 hrs before me classmate had to go 2hr away as earliest time locally was 3 weeks away. An hour after I registered, classmate was able to get next morning. Looking now is what is now. It can change in an hour or days.

OP, the quickest way to answer your question "how soon will I be able to test?" would be to say "as soon as an appointment is available for you to book".

Beyond that....it's ALL up in the air.

In my area, if your schedule is flexible and you feel ready, there are almost always day before cancellations that you can snatch up if you want to test quickly!

I had to wait for it to actually see the dates unfortunately.
