When will I hear back from the schoolhouse for decision on my class seat (Reservist Reclass)?

I've been retired for 13yrs but in my experience, if my command didn't own the seat the wait list opens up at 30 days out. At which point any empty seats are filled first come first served. As a training and ops NCO I always checked on my soldiers in a wait status at 30 days out up until 10 days out for any cancellations I could slip them into if not already in a reserved seat/status. Unfortunately it's hit and miss if your command doesn't already own the seat. Again, I've been retired for 13 yrs almost, things may have changed. Good luck.

The course is very long, phase 1 runs from 25 JUN to 18 DEC at Ft Sam.
The phase 2 could be at Ft Sam or 20 other locations.
This course only has Army Reserve quotas for NPS (non-prior service). That is initial entry training. For reclass, you would be trying to get one of those unused quotas at 45 days out from report when it opens to all applications.
Your ATRRS profile should have your correct email address, and you should have received an email when the application was submitted. You would receive another email when that application is denied, or approved for a reservation or a wait.
If you never received that first email, you should talk to your schools NCO about correcting your email address in ATRRS.
You should also ask that schools NCO what level that application is pending today, (there are levels of review between input and approval), and if they have a plan to get a non-quota seat.
