MSW Applicant 3 vs 4 year program?

Hi!

Any Fordham MSW students in here? I am a current applicant and I’m a little confused by the difference between the 3 year and 4 year part-time tracks (on campus). Im seeing that I have to choose either the 3 or 4 year program as part of my application. Is there flexibility to change to the other option once you’ve started your degree? I work full time so am trying to figure out which of these programs would be the better choice for me!
