^ Petitioning is designed to provide students who experience unavoidable, extenuating circumstances, the opportunity to waive a University policy that, if enforced, would result in unsatisfactory academic progress or financial consequences. Non-degree students students must petition the Dean of Continuing Education. Degree students must petition the dean of the college in which they are enrolled and must have an instructor signature.
