School Self Renewal, rooted in the ideas of Organizational Development, is a process of school improvement undertaken with the participation of the members of the school community. Based on reports of Renewal projects in New York City Public High Schools, this paper presents some of Renewal's problem areas, strengths, and the implications of the assessment findings for the future of the Renewal process in schools. Some of the issues addressed include: definitions of School Self Renewal; goals of Renewal in schools; reasons why individuals participate in Renewal activity; and costs and/or disadvantages for those who participate. In examining changes in school life that are to be the products of Renewal activity, this report points out certain developmental patterns which seem to indicate the flow or growth of Renewal activity in a school. The area of evaluation is described as one flaw in the execution of Renewal projects, although otherwise, it is concluded, Renewal works well. (Author/EB)
