Honestly, I knew people who were in that program, we had classes together, but I really don't remember. Sorry! I think the big difference is that they spread the internship out so that it goes for 12 months (fewer hours each week) instead of 8 months (21 hrs each week). But I could be remembering wrong. I think other people in the program kept their existing social work job and that counted towards their internship.
If it's the program for working professionals I'm sure they make it manageable. They're super nice and will usually work with you to fix any problem.
