Does anyone know what this means “on a rolling basis beginning april 1” for transfer notification?
Starting on April 1, they will send out the acceptance/rejection letters. They will continue to make admissions decisions after April 1, and they will notify those later people as the individual yes/no decisions get made. This isn’t at all uncommon, especially at public universities that might continue to admit transfers right up until the fall semester starts.
So, if you want to know yes/no earlier rather than later, be sure to get your application in well before the deadline.
