We do pre-employment checks and education - degrees and certifications are part of what we do. I am not commenting on any of the examples you raise as to good or bad or whatever, but let me say that my short experience in Hong Kong suggests that there is a pecking order of institutions when you apply for good jobs that is even more prevalent than in Canada.
If you get a degree from any of the 9 or so HK universities, you will find them acceptable I'd think pretty much here or anywhere. They pass the smell test which is not always true for non-traditional programs where it is online or some combo. But you can see on this site the IB boys love them higher rated MBA schools over the locals.
Be careful of accreditation. It is not about that as much as it is about public or employer perception of the value of the degree or the worth of the specific program. For example, HK's universities are self-accrediting while particular programs are accredited by other organizations in the specific disciplines. Most students can never tell you the accreditation of their program or if their university is accredited. That is not the primary issue.
Here in HKSAR a short time ago they rejected a bid by the Institute of Education to become a university. This says that right or wrong HKSAR has standards.
I have come across websites where the HK course provider says the program is fully accredited as does the parent university. Only when we checked the website of the accrediting organization it is at the top of the list of revoked accreditation with no appeal and has been that way since August of 2008.
If the goal is a quicky bachelors degree it can much like quicky sex where you haven't checked out the sex partner and later find out the quicky had STDs and she's now pregnant, everyone knows about it including your partner/wife and now your reputation is shot and it's going to cost you a lot of money.
There are lots of very good private educational bodies doing great work for folks here and elsewhere. You just have to be very, very careful when you enrol and pay a lot of money for a university degree program if it is not offered on a traditional class room basis. All those you note may be terrific but ask around.
Remember beauty is in the eye of the beholder and if it doesn't pass the smell test save your money.
I know many knock the Associate program as it is not a full out university in academic situations, but if that is all I could afford I'd rather take my chances with that and have a transcript that shows top marks than risk a non-traditional program that employers disavow. I'd find some other way to build my qualifications and experience than risk money if no one thinks it has value.
Most of the bad stuff we get here are fakers who say they have degrees and transcripts from the best universities in North America and Australia but bought them from some guy in a parking lot in Toronto.
The funny thing is that every time we get a non-traditional or "degree mill" sort of program, out of interest I Google it and bingo you will find someone out there in this town or region showing it in their credentials on the internet. But when the SCMP or Singapore's Straits Times get on these cases, it becomes embarrassing to their organizations and to the degree holders. HK has many stories like that.
