I’ve found that pre med/pre professional counselors in university tend to be some of the worst sources for information. They get things almost right, but still wrong enough to add significantly to confusion. They are best suited to providing info to the best students, and tend to drop the ball for folks with more complicated needs. It’s mostly the high achievers that make the cut anyway, and they know that everyone else’s chances decrease exponentially with lower academic marks, while their drag on the counselors time for the lower achievers increases exponentially with lower academic marks.
The message on the whole is essentially correct, but the details are muddled. CASPA will allow you to fill out an application and thereby apply to any of the programs, and they will take your money (and so will the programs), but with a GPA below 3.0, you are up against strong headwinds in terms of getting accepted. Most schools won’t realistically consider folks with a GPA below that even if they will accept your application fees. 3.0 has been a historically accepted minimum cutoff, but I wouldn’t be surprised if it was much higher at this time. There’s just too much competition with grades too high. If you have a reasonable GPA cutoff, you shed a large number of folks that are statistically far more likely to not be equipped to keep up in a demanding program like physician assisting. Programs move fast, and can’t have folks holding back the other students or failing out and wasting valuable seats. When there are 10 applicants for each PA seat, and 4 of those 10 applicants have GPAs above 3.7, you don’t get anything from dipping down to interview folks with sub 3.0 GPAs.
