Students in high school were in to rampant cheating YEARS ago. When I tried to get it stopped, the administration and parents went after ME.
About ten years ago, I worked one semester for a for-profit university (not one of the common big-names). In their orientation they spent more than half of the time discussing academic integrity, that it was to be strictly adhered to, that all examples were to be sent to the administration, etc. I was impressed by their concern. For the first written assignment in my classes, 1/3 of the students fully or mostly plagiarized, and I followed the college protocol for every student. I was not invited back the next semester.
