Almost all PA programs award a masters degree these days. A rare few offer a bachelors degree, and fewer still offer a PA associates degree. There might still be a certificate program out there, but I'm not sure.
Most PA programs require applicants to have bachelors degrees before applying to get into their PA schools to get the masters degree in physician assisting. After you get your PA masters degree, you take your certification exam, and then can start practicing as a physician assistant.
So it sounds like you have funding available for you to get a bachelors degree. In your case, you would use that money to pay for a bachelors degree like a biology degree for example. Once you have that bachelors degree (and it doesn't have to be in biology, but you do need to have completed the prerequisite courses that PA schools require) then you apply to PA school to get the masters degree in PA. Many times that takes basically 6 years total to become a PA (4 years for your undergraduate bachelors degree, and 2 years of PA school to get the masters degree in PA so you can practice).
