Last year - once the 1st year commit deadline had passed, and they had been busy the first week of May to reach out to 1st-year waitlists, they then moved on to release transfer decisions (remember - limited staff, so they have to stagger their projects).
When decisions were released last year (Barnard Transfer Fall 2022 - #223 by Giraffe6), 2nd week of May, they were accepted, denied or “waitlist”. Come June, unless someone de-committed, one would not expect movement.
If they follow the same procedures, one would get a definite response. In that case, NO response would NOT mean “denied” - it likely just means they haven’t finalized their decisions yet.
