The award of a sabbatical leave is protected by the Constitution and Bylaws, Article 8, for the purpose of supporting and encouraging faculty scholarship (research or artistry). The evaluation of faculty members’ proposals begins in the department; however, it is the ranking based on relative merit within the college by the dean and the college council that will determine if a sabbatical is awarded. Sabbatical leave is available to faculty members who have completed six full years of service at NIU and are limited to tenured faculty and non-temporary supportive professional staff (SPS). The college does not provide replacement teaching for faculty on sabbatical leave; therefore, the department chair should ensure that there is sufficient teaching personnel to cover the course load of the department in a faculty member’s absence. Sabbatical leave can take place during a single semester for full pay or for an academic year for half pay.
