Hope you are doing well. PA School's have very competitive programs. From my experience, students attend college to receive a Bachelor's degree. In the meantime, I have seen students complete CNA / EKG Technician certifications to gain Patient-Care Hours as some schools may require about 1000 hours during their undergraduate career. Depending on the program of interest, schools may require you to take the GRE which is a graduate school entrance exam and/or take some specific electives like Microbiology. Overall, I say complete tasks that will ultimately make you a more competitive candidate. Good luck with all of your endeavors.
Ashley recommends the following next steps:
Attend a 4-year university and obtain a degree; make sure to get outstanding grades.
Make sure to make time for clinical shadowing, volunteering and maybe even research. PA school is very competitive and many students do not get accepted their first time.
Good luck and don't give up!
