The results of a study conducted by the National Commission on Resources for Youth, Inc., (NCRY) to demonstrate the feasibility of a Youth Tutoring Youth program (designed to put 14- to 15-year-old disadvantaged underachievers to work as paid tutors of similar elementary school children) for possible implementation as a project of the Neighborhood Youth Corps (NYC) are the subject of this final report. Opening sections describe the philosophy of the tutoring program, emphasizing its several levels of impact (improvement of self-concept, study habits, tutee work, school-community relationship, and school reform efforts toward dropout prevention) and the history of the program, outlining two demonstration projects and a program model (developed from the demonstration projects) used to develop and construct replicate programs. Brief descriptions of NCRY strategies for implementation and of the 1968 implementation of replicate programs in 13 cities, two community-controlled schools, and one rural area are offered in the following section. Closing sections deal with measuring the success of the Youth Tutoring Youth program (assessing the problems of evaluating programs which involve behavioral change, defining the goals of the program, and discussing the case of a representative tutor) and future NCRY assistance to NYC. Appended are a description of the Philadelphia Public School program and of internships, one of the NCRY strategies for implementation. SP 002 593 and SP 002 204 are related documents. (SM)
