Hi @faithcarol !
Sorry, I haven't checked the forum in a while.
Anyways, so I took two courses through the SDSU SLP Essentials Program (SLHS 300 and SLHS 320), and I just started my post bacc at CSUF this fall. SLHS 300 Introduction to Language Science did not transfer into anything for me. However, SLHS 320 Phonetics did, so I didn't have to take Phonetics here at CSUF.
In short, those 8 classes would not cover everything. In fact, some of the classes might not even be the same classes needed in specific postbac programs. The masters programs that I have looked at usually asks for at least 10-12 specific courses. CSUN, on the other hand, will not transfer any of these courses over into their postbac program. They want their students to strictly follow their written schedule.
I would check specifically with the schools you are applying to, because some courses will not transfer over, but some will. You can simply look at the course names and descriptions to compare. For reassurance, you could also contact the coordinators at the Postbacs you are hoping to apply to, so that you can see what would transfer over. That way, you won't blow $951 on a class that is irrelevant to the program's requirements.
Hope this helps!
