The Collaborative Supervision Project involving the University of New Hampshire and several public schools is described. This paper addresses the university teacher education interest in enhancing supervisory effectiveness and the teacher education faculty during the initial planning stages and the development, demonstration, and dissemination years of the project. A description is given of the context of the collaborating school district. A directive from the superintendent to the principals in the district to investigate different models of supervision resulted in two years of self-study of supervisory effectiveness. This led to the school district's interest in joining with the teacher education faculty to mutually develop a program which would address supervision issues. Successful practices are described and the way in which the project addresses some of the Holmes Group goals is summarized. (JD)
