How long after recieving drill sergeant school dates will my wife here where she will be stationed for drill duty?

She could get orders right before or during ds school.

Has to pass the course 1st, then they will assign her.

She can also look at her sponsorship form, it might show the gaining duty station. That's how I found out I was even going to school, I looked at the 5435 just to update and it said Fort Benning with a report date. I was confused because it was very specific. I then looked into ATRRS and saw my school dates. But like everyone mentioned, she can look on her ERB.

And as for ASK...That page has been down for a long time.
