A few miscellaneous comments . . .
Pennsylvania has traditionally been one of the tightest states regarding regulation of academic programs. As a general rule, unaccredited degree-granting institutions have had to be evaluated by the state for licensure purposes every five years. Most, but not all of these schools, tend to lean toward the religious fields, and some historically had a doctrinal objection to accreditation at one time or another.
An example of this is Calvary Baptist Seminary in Lansdale, which comes from the BJU (Bob Jones University) school of thinking - in fact, they historically had several BJ graduates on their faculty. CBS has had one of the best graduate theological programs in the state (for those who can appreciate the Fundie line of thought), but for years avoided accreditation because of doctrinal objections. However, even they were accredited by Middle States in 2009, as many schools around the country lessened their objections over the years. (I often used the CBS library when I was in the Union program and teaching at Biblical Seminary, a few miles from CBS.)
Today's accreditation environment is certainly different from the mindset that was going around in the early 90's, when the prestigious Westminster Theological Seminary got into hot water with Middle States because their board of directors lacked gender diversity. As I recall, Westminster gave into MSA, although I had the impression that they didn't really need to do so.
Regarding Joe Alercia - he's a classical, old-fashioned private investigator. At one time, his school was accredited by one of the CHEA-recognized trade school accreditors, but it's always been largely a one-man show. (My oldest brother, who is a PI, has worked with Joe at one time or another.) I think their current status is merely a matter of Joe taking a more laid back approach as he ages. Nonetheless, in the PI field, degrees have never been a major issue - as in music, for example, it's not a matter of credentials as much as
who you studied with. And H.G. is right - fields ranging from barber/cosmetology studies to massage have never been degree-based in terms of credentials (or even licensure), but diploma based.
Incidental note: For certification as a weapons instructor under Pennsylvania legislation, the State Police have traditionally required at least an associate's degree. During the time that Joe Alercia issued degrees, the police
did recognize Lion Investigation Academy degrees, even when unaccredited, as an acceptable credential for instructor certification.
Final note: One of the reasons Pennsylvania has such a good track record is the head honcho in the Department of Education for licensure licensure issues, Warren Evans. Warren retired several years ago, and I don't know how effective his successors have been in this area (remember, I'm retired from this field).

I met Warren when I organized the Institute on Religion and Law back in 1991, and had to clear the use of the word
Institute with the state DoEd for registration purposes (certifying that IRL would not purport to issue degrees, etc.). In Pennsylvania, terms like
college, university, seminary, and
institute are still regulated, and their use must be approved by DoEd.
By the way, I'm delighted to see that the Won Institute achieved MSA accreditation. They are located only six blocks from where I was partially raised (I spent my high school years in Glenside) and always seemed to have a very credible operation. Not my particular cup of tea, but the school has always had solid programs.
