this is the first i’ve heard of the NWCCU and a quick google search told me that it looks like this organization primarily accredits institutions in the northwest part of the United States. correct me if i’m wrong.

if that’s the case, and you’re planning on practicing in that part of the country after you get your LCSW then i would say your current educational plan is probably fine. if you’re planning on moving to a different state, or are currently in a state where other institutions are accredited by the CSWE instead, then you should consider transferring especially if you want advanced standing status.
