Cooperation between colleges and schools is considered in seven chapters. Attention is directed to academic standards, accelerating students, teacher preparation, experiments in transition, minorities, and special models. The analysis is intended to illustrate the great diversity of partnership activities in progress. In an introduction by Ernest L. Boyer, conclusions of the publication are identified as follows: high schools and colleges should cooperate to determine the content and specific skills considered essential for college entrance; students should be free to move at their own pace to make the transition from school to college; programs for beginning and senior teachers should be collaboratively developed by colleges and schools; experimental transition schools should be established that combine the school-college years and avoid curricular overlap and duplication; collaboration is required to identify disadvantaged students at an early age and to provide the assistance they require as they move from school to college; and colleges and universities should establish a partnership with one or more school districts to provide educational and cultural enrichment as determined by principals and teachers at the schools.
