As noted above, in the granting or denying of leaves is generally at the discretion of the department Chairs and school Deans. Schools have different policies and practices with regard to sabbatical leaves and other leaves of absence. To the extent that these may be at variance with University-wide policy, advance approval must be obtained from the Provost by the department Chair and the school Dean. Exceptions to the University’s leave policies may be approved by the Provost, at the Provost's discretion. Questions regarding leaves should be referred to the school Dean’s Offices.
