The change from IFS to IFT was driven by the new Commander of AETC. He felt that the syllabus and intent of IFS was too inflexible and that (essentially) people who were on the ragged edge of being successful were being washed out because the IFS policy did not allow the school to give them the extra ride or two (i.e., a little additional training) to enable them to succeed. It was a waste of the AF's time and money to wash them out. That policy change reduced the emphasis on "screening" and increased the emphasis on "training". That doesn't mean you can stay and fly forever, and it is still a screening program, but it does mean that now if the IP thinks you can pass with just a little more opportunity to train/practice, the school is allowed to give you a ride or two to prove it. If you do, you continue, if not you wash out. Other than that policy change, the school is still the same. The change in title from IFS to IFT was meant as a signal of the change.
