It sounds crazy, but quit your PT Aide job. Why? One reason and one reason only. VARIETY. Let's say I had identical stats as you with the exception of hours. Let's say I had 200 hours but from 3 or 4 different settings. You obviously have more hours than me and we have identical stats so you would get in over me right? Wrong. There is a very good chance that I would get in over you because PT schools want more of the variety of settings over amount of hours. It is obvious that you already have the amount. But now you need the variety.
I might be a little hasty to tell you to quit your job as a PT Aide. The reality of it is this: If you can still work there but volunteer for inpatient settings such as hospitals and nursing homes, you would be in a perfect situation. However, bills are important too and trust me, your going to need every penny for your application fees, sending GRE scores, securing your seat with a confirmation deposit WHEN you get accepted.
So if you need the money, take the other job and get as many hours as you can in different settings aside from outpatient. Justify your decisions truthfully on your application when the time comes by stating that you quit your PT Aide job to get more experience in different settings and to save for upcoming application fees, costs, etc. As long you justify your decision to a decision that will further yourself in the world of PT, you will be fine. Anyways, get that VARIETY. It means more than the amount and you already have the amount! Get at LEAST 20+ hours in each new setting you explore and you will be sitting pretty good! Good luck!
