It would be interesting to see how well the screening does, when it gets to numbers of students starting the course compared to the numbers finishing.
50 years ago when I joined the RAAF, there were about 400 applicants for each pilots course. Of those, 40 would be selected to start the course, and of those, around 20 would get their wings.
This is a success rate of 5% from the initial applicants, and 50% for those deemed to be "Meets Required Standard."
Does this more-thorough screening process increase the finishers:starters ratio?
