All the "minimum" means is that you are able to enter the potential applicant pool. No where, on any program's website, does it say that people with the minimum requirements have the same chances of getting in as those with the higher scores. I cant really imagine a school taking someone with a 3.0 over someone with a 3.6 or higher, assuming both have relatively similar interviews and extra-curriculars. The only way I see the 3.0 getting a chance is if they spend a lot of time after undergrad working as an Aide (proving they want to be a PT), have a life-changing experience like going overseas (making them more mature), or blowing the adcomm away at their interview while all other applicants sit in their chair and have the communication skills of a tree.
I think it is important to remember that the field of PT is growing, and I have heard that the current application year is larger in applicant numbers than normal. To be honest, if you are one of the people who has Minimum scores, and you still think PT is the right field for you, I would highly advise that you apply to as many schools that you can. There is no way you can be picky. You simply need a school to take a chance on you!
I hope I did not upset anyone with this post. I am sure you are all great people and will make great therapists. I just think that we need to be looking at our own situations realistically, and if this is really the profession we want, we must do all we can to make it a reality.
