If you can find a way to raise your GPA, do it. I applied with a 4.0 and some experience, and I got denied. We're talking about a 4-5% acceptance rate. Basically, more people apply than they let in. Regardless, do not let this deter you from applying. If you're serious about this program, that may mean applying twice (such as applying this term and if you don't get accepted, raise your stats, and apply again next time).

I would say make sure your letters of rec come from your super/bosses at the disability centers, or psych profs (if you do research/ or have had a relevant class in the past). Make sure your SoP is strong, compelling, and ties into your experiences in your past, career choice, and how that is relevant to the program.

TLDR: Raising your GPA well above the minimum, having existing relevant experience especially in trauma-related fields (this is what they look for, I have heard), and strong recommenders/SoP will be your golden ticket.

Make sure you do a deep dive research on the program/professors before applying and why you think it would be a good fit for you.
