The information is quite limited. Beginning Feb 19 programs will be able to run a report to see the aggregate number of individuals who have selected "Plan to Enroll" for their school and the number who have selected "Plan to Enroll" for other schools. There are no names attached to these numbers; we will only know that, a total of 4 individuals have selected plan to enroll for our school, and 3 have selected plan to enroll for another school. On April 30, we will be able to see names and statuses of all individuals who are holding acceptances at our school.
Prior to the 2019 cycle, we could see all the current acceptances of those individuals holding acceptances at our program beginning in mid-February. This allowed us to make an assessment of the likely yield of those holding acceptances, and perhaps make additional offers before May 1. For instance, if I saw that an applicant was holding an acceptance at a school that might be more desirable to them personally due to location, research fit, prestige, etc., I might decide to pull someone off the waitlist at the beginning of March, rather than wait until I get a decline email on May 1. The waitlist grows stale quickly, and someone who might have been willing dump Fencer's program for mine in February might get tired of waiting and decline our offer after May 1. That happened to us last year (though not with Fencer's program). We had an applicant that I spoke with 2-3 times a week throughout the month of April. He was in another program, but really wanted to come here. We were oversubscribed, but I told him that we almost always took someone off the waitlist. On May 1 I told him that several applicants still had multiple "Plan to Enroll" statuses, and there was a good chance we would be going to the waitlist. However, he decided that he could no longer wait, and committed to the other program on May 2.
