I am looking into applying for a couple of art therapy grad programs. I have a B.A. in Theatre and graduated in 2011. The art therapy programs that I am looking at both require 12 credits in Psych and 18 in Studio Art. I have no psych classes under my belt, and my art training was all through THEA classes (along with out of school training). The admissions counselor recommended that I take classes at the local community college in order to get these prereqs. I already have my A.A. and my B.A. and am really concerned about taking even more classes at a community college just to *maybe* get into grad school. Is this a common occurrence?
