Since the chances of enrolling the intended class size on the first attempt fall at essentially zero, it would seem that colleges that do not accept from their waitlists (whether early or later) have mismanaged their admissions (by nearly inevitably over-enrolling their classes). Regarding yield this year at Hamilton specifically, they would need to enroll 75 students from the waitlist in order to reach an overall yield similar to that of last year. Based on this figure, Hamilton appears to have been conservative in their initial acceptances in order to allow for the possibility of an uncommonly high yield.
