Different places have different rules about accepting transfer credit. Most of my experience has been along the following lines:
Note: It really, really, really helps to have the full catalog course description, the syllabus including the titles of the books of each course you want transferred.
Someone in admissions approves credit for “generic” courses. English 101, Western Civ., etc. If they seem like an okay match, you could get credit for the corresponding course at the new place. Sometimes, all you get is credits in a category only. E.g., you get 9 hours of English credit or Social Science credit. And even then you might get 9 hours of credit for 15 hours of courses. Just because.
For a bit more advanced (and frequently not the least advanced) courses, someone in the corresponding department checks it over. I was this person many, many times at different places over the years. (It’s a job on the “someone needs to do this” list and if you’re a junior prof, volunteering for one of the easier jobs is smarter than having one of the nastier ones dumped in your lap.)
So the admin sends the student over, I ask for the catalog description, syllabus, what text was used, etc. I get a blank stare. Send them away. Maybe they’ll come back later with the right info. (It is astonishing to me that students cannot name the book they used for an advanced course in their major that they just took. I can recite the author’s of books in courses I took decades ago.)
If there’s a corresponding course, I fill in and sign a piece of paper. Sometimes I also got to set how many credits matched up. (Having taken Operating Systems to fulfill a requirement isn’t the same as getting 3 or 4 credits for a course.)
The last place I did this the transfer credit stuff was required before a student could take a summer course or some such elsewhere. Once enrolled, all later outside classes had to be approved. This was smart. Saved a lot of headaches.
One key thing: There are always limits as to how much total credit can be transferred. Maybe half or so of the degree total in many cases.
If I was reviewing transfer credits for a UofP* courses in my field, I suspect the chances are the answer would be nope, nope, nope. The student might be lucky to get only credit for some of the hours, not for specific courses. Not rejected just because it’s UofP, but because I suspect the courses won’t really qualify. A distinction that certain people should note carefully.
*The University of Portland must be POed at Phoenix. Smear by similar acronym. It’s a really respectable place. Kunal Nayyar attended there. If it’s good enough for Raj …
