Describing and analyzing the impact of Outward Bound (OB) programs on 12 high schools which reflect OB involvement varying from 1 to 5 years and include urban, suburban, and rural (public, private, boarding, and day) schools, this 1970-71 report is aimed at furthering OB philosophy and method. The report presents OB program: background; evaluation procedures; initiation rationale; funding; impact analysis; recommendations; and generalizations. Brief program descriptions are presented in the Appendix for: East High in Denver; Toledo Public Schools in Ohio; Trenton High in New Jersey; Churchill High in Eugene, Oregon; Concord-Carlisle in Massachusetts; Lincoln-Sudbury in Massachusetts; Minnetonka High in Excelsior, Minnesota; St. Alban's in Washington D.C.; Sterling School in Craftsbury Common, Vermont; Webb-Bell Buckle in Bell Buckle, Tennessee; Germantown Friends School in Philadelphia; and Adams City High in Denver. Major recommendations presented are OB should: not impose its philosophy upon its participating schools; be sensitive to institutional and administrative program readiness; leave program direction/development to school personnel as soon as possible; consider the kind/degree of OB involvement (special vs mainstream); and continue to encourage information dissemination among participating schools. The conclusions presented re: OB impact are OB programs: function as a catalyst; legitimize experiential education; and serve as a vehicle for curriculum reform. (JC)
