This collection of essays on school climate seeks to provide a broad perspective on climate evaluation and to suggest activities that can improve working conditions in schools. Written by practicing educators who have exercised leadership in school climate improvement projects, the articles are divided into two sections: evaluation and implementation. The section on evaluation includes a definition of school climate and the principal's role as a climate leader, a discussion of school assessment, presentation of a school climate assessment instrument, and a description of the School Climate Profile survey. The section on implementation covers the relationship of staff development to school climate, ways to improve classroom climate, the problem of discipline, shared governance of schools and the rights of parents, and strategies for implementing school climate activities.
