Do you have to take an APFT 30 days before School?

If I remember correctly it has to be within 30 days before a leadership school.

Taking a Pt test prior to attending a school is not a requirement in any regulation, however you will be required to pass a Pt test when you arrive to the school house.

Check out tradoc 15-10.
You are not required to take a Pt test before school but you are required to pass one upon arrival to your class.

Yes

It would be a unit requirement. However, refer to the ATRRS info or school MOI for more info. If it isn't a hard requirement, but your unit wants one maybe they will allow you to negotiate based on prior performance and work issues.

Sir,

I am reporting to recruiting school next Monday. I was instructed to take another since the last was over 30 days ago before reporting to school. It normally stated
that you need a test 30 days prior to attending a school and you get tested again. Within the first week or so.

Yes if they are NCOES schools esp. 60 and 30 days out just to make sure you pass once you are at the school if not then your state will get dinged and will funding for the next fiscal year.

Unless it has changed in the last 3 years, APFTs are given during the first few weeks of any major school.

The requirement is twice a year, nevertheless a commander can have them every month if s/he wants; not recommended!

Wouldn't you be due one next month anyway?
