How might independent schools play an effective role in educational reform through public-private collaborations? This study, a project of the Klingenstein Fellowship, surveys the types of partnerships, explores varying degrees of collaboration, and examines the impact of collaborations on schools and communities. Portraits of five collaborative projects between public and private schools are presented: (1) Springside and Philadelphia All-Girls High School (Pennsylvania); (2) Crossroads and Los Angeles Public Schools (California); (3) Aim High: San Francisco (California) and St. Louis (Missouri); (4) Katherine Delmar Burke School and Martin Luther King, Jr., Middle School (California); and (5) The Hyde School of Greater New Haven (Connecticut). Contains a directory of 30 collaborative programs that work and 3 appendices that provide an overview of school-university collaborations, school-business partnerships, and a copy of the survey. (LMI)
