As an FIE, if somebody came out with that sort of rubbish when I was testing him or her, they would fail the test. If it was an initial test I would discuss the matter with the school that "taught" him and, if necessary, take the matter up with the CAA. The FIC course is bad enough as it is without having individuals being taught to teach something so blatantly wrong.
DFC, the only thing that the CAA approve is the syllabus. It has practically no say in how it is taught.
As for the lack of elevator authority at low speed, it sounds as if the aircraft in question is one of those that has been designed to be "unstallable." This is a load of nonsense in its own right because if you were to fly at 100 knots and pull hard enough there would be plenty of elevator power to get the nose well up to the stalling angle of attack.
