Tagging onto this thread. I applied for Masters/Specialist programs at: Tufts, Northeastern, UMass (eta: Boston! Not Amherst!) and William James and have had interviews for all. I have already have received acceptance and a small scholarship from William James.
Based on my interviews, I felt the most congenial vibe from Tufts students and faculty, so I'm a bit dismayed to find that perhaps it is really hit or miss. My undergrad is in the area so my interviewer and I immediately had a connection and we began talking about mutual contacts. The students seemed happy and friendly. I found that Tufts and Northeastern really opposed each other for some things. Tufts seemed to disapprove of behavioral programs and stressed that there was no ABA component, while Northeastern actually offers School Psych students to receive APA training as a concentration. I'm not sure what to feel about that. I felt as though Northeastern professors were the most engaged in practical research and were very excited to talk about it. I feel pretty neutral about UMass -- I didn't feel as though there was a great connection between the students and faculty, and didn't feel as though I really got a chance to "shine" as we did not have individual interviews. William James is a solid option although I wonder if it being less "known" would have an impact.
I am going to wait for acceptances and aid to come through. Based on the "feel" at Tufts, I feel as though I would be the most comfortable there and likely will receive aid there, but I am not sure how to pass up Northeastern's academic breadth and rigor.
