i suspect, but don't know, that this includes professional schools like pharmacy, which doesn't require a prior bachelor degree for entry because of waning popularity and the need to bring in students to survive. they still supposedly have to pass all the prerequisites, but i witness administrators work around this to up the numbers. one can also enter an mba program without a prior degree. these are very different than phd programs. be interesting to know how those numbers break down.
i was the chair of a (bsc) university's academic standards council for a few years, which was made up of about half administrators/half faculty. we set the standards for admission and retention, and the requirements for both became less and less stringent in order to bring in more students. the vote was usually pretty split, with one or two reliable suck-ups voting with the administrative half to give them a majority. it was about this time when everybody was starting to count affiliated colleges of technology and any other program they could to increase reported #s. i was also the faculty chair at another university for a couple years, and there was a big push to count 'work experience' credits to enroll people who were working jobs as students. been in a business management position for a long time without a degree? no problem, give us some money and we'll give you one, and count you as a student... that particular policy was driven by the university board of directors, who had little interest in hearing the faculty's position.
so anyway, i always take these numbers with a grain of salt. sorry for the long post.
