This is a group of faculty members who formally evaluate your work at the qualifying, dissertation proposal, and dissertation stages. The committee must have at least three members, one of whom serves as chair (or two as co-chairs). Members must represent at least two academic units, one of which is UNT LIS, and have appropriate graduate faculty status. One member can be external to UNT, provided he/she holds a PhD and is approved by the Graduate School. After you pass qualifying, the advisory committee usually retains the same members, but is called the dissertation committee.
