Well, it’s kind of a long story.
The applicable rule seems to be Article 42.1.2 of “Qualifications and Criteria Standards for foreigners undertaking the jobs specified under Article 46.1.1 to 46.1.6 of the Employment Service Act.” The English translation of that rule says simply “Be graduated from colleges or above,” where “colleges” probably means something like junior colleges. It adds that graduates of junior colleges need “qualification certificates for language teaching if they have not obtained bachelor’s degrees.”
One English version is here:
One Chinese version is here:
However, the Workforce Development Agency seems to say that the Ministry of Education determines which foreign institutions of higher learning are acceptable (so far, I haven’t been able to find this FAQ in English):
The Ministry of Education has a Reference List–which is something like a “list of lists”–of foreign institutions of higher learning, with a search function located at this page:
One of the tabs on that page leads to a world map, and you can click South Africa on that map, and then click the white rectangular button that says “查詢” (“inquire”), and it should give you the Ministry of Education’s list of South African institutions of higher learning.
Another way to get that list is to use the other tab, and for the dropdown menu that’s labeled “洲別” (“continent”), choose “非洲地區” (“Africa Region”), and for the dropdown menu to the right of it that’s labeled “國別” (“country”), choose “南非” (“South Africa”), and then click the white rectangular box that says “查詢” (“inquire”). Again, that should give you the Ministry of Education’s list of South African institutions of higher learning.
I don’t see Pearson Institute on that list. However, I agree that it seems that Pearson Institute is accredited in South Africa.
The website of South Africa’s Council on Higher Education says:
To verify whether the institution or programme is registered and accredited consult the Register of Private Higher Education Institutions at: http://www.dhet.gov.za/
The above instructions are located here:
At the website that the instructions refer you to, you can find Pearson Institute on these two lists:
“REGISTER OF PRIVATE HIGHER EDUCATION INSTITUTIONS”
“REGISTER OF PRIVATE HIGHER EDUCATION INSTITUTIONS

I wonder if there’s a way to get in touch with either Taiwan’s Ministry of Education or the Taipei Liaison Office in the Republic of South Africa (http://www.taiwanembassy.org/za_en/index.html), or whoever it is that needs to be gotten in touch with, and see if you can get some documentation that would satisfy the requirements of the Ministry of Education, or whoever it is that needs to be satisfied.
I hope this helps, or at least does no harm, and I wish you the best of luck in your efforts to make a living.
