Per UIUC's admissions brochure (on their website):
"The initial applicant assessment ranks individuals numerically according to a composite score derived from their cumulative and science grade point averages, their graduate record examination score, and an evaluation of the rigor of their academic experience.
The second stage of the assessment process is a non-academic evaluation of the VMCAS Application and the College of Veterinary Medicine Supplemental Application by the Admissions Advisory Committee. The non-academic score is determined using the following factors: VMCAS Personal Statement, CVM Supplemental Personal Statement, veterinary related experience, animal related experience, other career experience (research, lab animal work, business experience, agribusiness experience, etc.), community service/citizenship, leadership, initiative/enterprising activities, any special recognitions (academic, personal or professional), and letters of reference.
At this junction a preliminary order of merit list is developed and a determination is made as to which applicants will be offered the opportunity for a personal interview. Once interviews are completed, the final, official, order of merit lists designate resident and non-resident applicants who will be offered admission."
