The C3C's father you were speaking to was mistaken. Not unusual being military jargon and such is it's own world. Once you're a cadet, you don't take the CFA any more. Therefor; the C3C's his father was speaking of, couldn't remediate doolies that don't pass the CFA. CFA is "CANDIDATE Fitness Assessment".
Now; what the C3C could be monitoring is the cadet's taking their PFT (Physical Fitness Test) and/or AFT (Aerobic Fitness Test). And while there are obviously similarities between the various "Fitness Tests", they perform different purposes. And yes; some cadets have a difficult time doing the PFT or AFT; which I believe is done twice a year each. So yes, they need remedial.
However; the CFA is for "CANDIDATES". And YES, you MUST TAKE IT. Just like Flieger and others have said. That is NOT NEGOTIABLE. And you must PASS IT. That too is NOT NEGOTIABLE. If you failed it, you are not going to be a cadet. Now; what is a "Passing Score". Can't tell you that. (Numerous Reasons). Mainly because it isn't stated clear cut publicly. However; there is definitely a failing score. I.e. Can't do ANY pull ups. So, to answer the original posters question; which has already been answered by others; the class of 2016 DID take the CFA, and their scores DID count. And no icarus, there isn't a cadet doing the job at the academy to remediate doolies who didn't pass their CFA. There is a job to remediate individuals who didn't pass their PFT/AFT, but that is NOT the same as the CFA they took when applying to the academy. Mike.....
