I feel a little weird putting all the numbers on the internet, but basically I had a GPA a little higher than the median, high writing/ verbal GRE, lower quant GRE. Undergrad in psychology from a moderately high ranked liberal arts college. I had 4 LoR - two strong letters from professors who know me well, two from supervisors. I spent a lot of time on my application essays, which I made longer than the cut off, and I was sure to include a lot of suggestions from Melanie that I got when I met with her (highlight my interest in child development, Spanish-speaking populations, the purposeful switch from psych to social work, interest in poverty as a risk factor, etc.).
I will say what I was most concerned about was experience - I only graduated from undergrad in 2010. I have one year as an Americorps volunteer/ intervention specialist in an elementary school doing various social and academic interventions (anti-bullying curriculum, small groups, etc), and this year I am working as a behavioral therapist for children with autism. I highlighted other past experiences as well, such as being an RA in undergrad, working in a deaf preschool, and volunteer work. I also highlighted significant academic experiences, such as research, a class in poverty and child development that affected me strongly, and my undergrad thesis (prejudice reduction in children). So for all of you fretting on not having multiple years of being a case worker, I still got in!
Something Melanie said that stuck with me - the people reading are professors, so at the very least, academics are appreciated by them from the perspective of who they want to have as a student. I really tried to highlight why I would be a passionate, committed student, as well as future professional.
Good luck everyone!
