Everything I've heard thus far about NYC MSW programs can be summed up in this: go to Hunter. The idea of NYU's well-regarded clinical track is a big draw, and even one quick stroll through Columbia's campus leaves me feeling like a more important person, but I have not heard any alum from NYU or Columbia who suggest that you will get the same perceived value in education that you take out in loans. All of the schools, Fordham included, send students to the same field internships. If certain schools were known for their private, personalized relationships with certain placements that would be a game changer (although I don't know how I'd actually feel about that, to be honest.) Some of the same professors at Columbia even teach at Hunter!
My sense is that some of the extra cost pays for hand-holding. I wouldn't expect or tolerate having to jump through the same bureaucratic hoops at an Ivy that I would at a city college. There's also the opportunity to take some of your electives within other departments or schools within the larger university or pursue a more extensive dual-degree. The facilities are nicer - I would imagine? It's a pretty nice feeling to tell your family and friends that you're going to Columbia for grad school, let's be honest, and I'd be interested in research done on the financial earning power over the course of one's lifetime based on name recognition of schools alone. All of these are good reasons for some people, not good enough for others.
All this to say that I would also love to hear thoughts from others who are making this decision or have already made it. Tell us why the private schools are worth it!
