<p>Here's information that was sent to me as an interviewer in an email:
[quote]
Interviewers are welcome to communicate with wait listed students to express their support. Especially in such a tough year, this is quite an achievement and they may end up being admitted to Brown.</p>
<p>There are several hundred students on the wait list. Once we know who has matriculated from the admitted pool by May 1, we will reassess the remaining candidates on the wait list.</p>
<p>Applicants on the list are not ranked, and it is difficult to predict what the odds will be for waitlisted students. In the last five years, anywhere from 0-90 students have come off the wait list.</p>
<p>We do not release past or current wait list information by school, state, geo, etc.</p>
<p>By putting the student on the waitlist, the admission commitee definitely believes the student is a great candidate, so it is not necessary to send extra material or recommendations to improve chances, However, the applicant should indicate their desire to remain on the list. If there has been a significant achievement or change in their record, they can certainly let us know.</p>
<p>Applicants should commit to another school by May 1, and if they come off the waitlist, they can then rescind the commitment to the other school. This is standard practice.</p>
<p>From a financial standpoint, admission from the wait list is the same as regular decision admission – it is need-blind for permanent residents and U.S. citizens.</p>
<p>Applicants will be notified by late May at the earliest if they are being offered admission.</p>
<p>As students are admitted off the waitlist, BASC will notify chairs and individual interviewers of the applicant's status.
