The Danforth Foundation Program for the Preparation of School Principals has recently been implemented at Georgia State University, the University of Alabama, and The Ohio State University, and it will soon be extended to another 11 universities across the United States. This article provides a brief description of a week-long specialized training institute that was developed and carried out at Ohio State during the summer of 1987. The institute sought to prepare a group of practicing administrators who were nominated by their districts to serve as mentors to a group of classroom teachers selected to participate in the Danforth Foundation Program for the Preparation of School Principals at Ohio State during the 1987-88 academic year. These designated mentors included 19 building principals, 3 assistant principals, 1 director of elementary education, and 1 superintendent. The objectives of the training were to familiarize participants with the goals of the program and with their responsibilities, and to develop personal and group understandings of the concepts, assumptions, and practices of mentoring. An agenda of the Danforth Mentor Institute is appended, along with a list of summary ideas related to mentoring in the Danforth program. (TE)
