I will be beginning a PsyD program in the fall, here's my info:
Research Experience: 1 1/2 years as an RA in a physiology/addiction lab
Clinical Experience: 1 semester (Sept-Dec) internship in an acute inpatient unit for adolescents in crisis (where I basically just shadowed, but my supervisor let me contribute to group therapy and write mock core assessments of patients once I became comfortable)
Undergrad psych GPA: 4.0
Undergrad overall GPA: 3.7
GRE scores: 160 verbal, 155 math, and 4.0 writing
Psych GRE: 630
Entering the program right from undergrad
I applied to 8 PsyD program, got interviews from 6, and then was offered admission to 5 (2 of which I was originally placed high on the waitlist for, but ended up getting offers)
So as you can see, I got in with way lower GRE scores than you. I think a lot of it has to do with which schools you apply to (like whether or not they're within your "reach" so to speak) and how you sell yourself. I got help from people in my research lab with my CV and personal statements, and one person who interviewed me told me I had very strong letters so I'm sure those helped a lot. If it helps, I applied to Rutgers, Loyola Maryland, Immaculata, Chestnut Hill, George Washington, Marywood, Widener, and La Salle. I got rejected from Rutgers and Loyola, offered interviews everywhere else. I didn't get into Marywood (I got food poisoning on the day of the interview so I asked them to remove me from the applicant pool because I already decided on what school I wanted to attend), and I got waitlisted at Widener and La Salle but was then offered admission to both. Not all of these schools required the Psych GRE (I forget which ones did).
My guess is that there are SO many factors that determine whether or not you get into a school, but I think you definitely need some experience so that they know you're serious. I know one girl who went on an interview and they were basically like "how do you know you want to enter this field if you have no experience in it?"--that's gotta be a tough situation to be in.
Sorry I wrote a novel, but I know how stressful applying is so I hope that this helps!
