We operated tech schools at one time, we had six of them, and it's not the same population. Our average student has been working seven or eight years. We have a highly disciplined student population. They expect a lot from the instructor. Instructors don't get to slide.
Students are much more demanding.
If a student fails, probably the instructor doesn't even have to fail him. That's because students are required to be members of study groups, and a non-performing student in a study group is expelled by the group. And they always drop out if they are expelled. That's quite a jump - that students themselves dismiss a fellow student. We've had a couple of court cases in which students say you required me to be a member of a study group, so you must provide me a study group.
