The committee is a panel of professors and pre-health advisors who evaluate your GPA, DAT, EC, etc and ask for you to submit 3-4 letters of rec from 3-4 different people (usually 1 dentist, 2 science professors, 1 liberal arts professor). The committee will then use those letters and will sometimes even conduct interviews of you to put into a packet to send off to TMDSAS or AADSAS.
