rosesw- all of the 3school you got accept will lead you to become a LCSW. Honestly, I would go for school that offers the most funding and visit schools.
I am currently attending second semester at NYU. You can become clincial (LCSW) from any MSW school. However, NYU is all about clinical and you must follow their cirriculum. Columbia you choose concentration during second year. (policy, clincial, and etc.) Overall, I would give 8 out of 10. Hunter is way cheaper than NYU or columbia. If you want to become a thearpist, NYU is good! If you care about Ivy degree choose Columbia.
From my experience, if your results doesn't come out by 1week of march you more likely to get a rejection letter. Columbia sends out rejection letter at the end.
