Louisiana's sabbatical leave law for public school teachers and state college faculty is one of the most liberal in the nation. Teachers are granted the right to sabbatical leave for purposes of professional or cultural development, and for rest and recuperation. While on leave, they receive partial salary compensation. The state of Louisiana spends approximately $5 million annually on sabbatical salaries. However, state law does not presently require that teachers on sabbatical leave return to the school system that granted them leave. Statistics indicate that only slightly more than half (59 percent) of the teachers granted leave for professional improvement returned to their original schools, while only 51 percent of those on rest and recuperation leave returned. Thus, in many cases both students and the public fail to benefit from the teacher improvement that sabbatical leaves are intended to nurture. The Public Affairs Research Council recommends tightening the sabbatical leave law to require, for example, that persons on leave return for one year to the school system granting them leave, or be compelled to refund salary pay received during the sabbatical. A survey of leave policies and laws in other states is included. (DS)
