go to FAQ: how large is the wait list

The College of Engineering offered a place on the wait list to approximately 2,000 candidates this year. This number sounds like a lot, but in truth, it is not the operative number. Of the 2,000 candidates offered a space on the wait list, approximately half will ask to remain on the wait list. Of those individuals who want to remain on the wait list, some percentage will drift away over April and May. They will develop ties to the college or university where they have deposited and their interest in Cornell Engineering will diminish over time. So in actuality, the operative number is much smaller than 2,000.
