Because you start as a PGY1. Psych is categorical, so it is only one "block". Specialties like Radiology require a preliminary year, so people can do a prelim somewhere else and go for pgy2+ at another institution.
So in terms of applying as a PGY2 I need to contact programs directly rather than ERAS? I'm honestly willing to start again as a PGY-1 but Id prefer to continue on as a PGY-2
