To be fair, the PIT enterprise at RND produces a flying instructor that is orders of magnitude better than what the FAA's CFI-creation process is.
I went to PIT as a salty O-4 who already had more than one IPUG program under my belt, and as @BashiChuni mentioned the "Instructor Fundamentals" academic course taught by the blue-suiters was the first time in my career that the AF had actually made an attempt to teach me how to instruct. It was probably one of the most useful academic courses in my entire AF career.
It wasn't perfect, by any stretch, but it actually codified processes to both platform instruct in the briefing room, as well as gave specific tools on finding root causes and instructional fixes to in-flight performance. It actually explained and put names on a bunch of tools that numerous Patch-wearers and IPs had been trying to explain (but were not actually teaching me) in the process of mashing my balls to mush in hour 13 of the DCA IPUG debrief.
That course at PIT could have actually used a healthy dash of improvement with some of the WIC processes that were vogue out in the ops world at the time (the "perception-decision-execution" method of root cause analysis, for example), but it was good. It is something that *all* new instructors at every level of the training pipeline could really use.
