The first half of this report reviews four major projects which are training tutors for cross-age and peer tutoring, and the second half outlines a model for training and using tutors in either elementary or secondary schools. The four projects reviewed are 1) Youth Tutoring Youth, operated by the National Commission on Resources for Youth in New York City; 2) Tutorial Community Project, operated by Systems Development Corporation in Santa Monica, California; 3) Cross-Age Teaching, an ESEA Title III Project conducted by the Ontario-Montclair School District in Ontario, California; and 4) Development of a Tutorial Program for Kindergarten Reading Instruction, conducted by the Southwest Regional Laboratory for Educational Research and Development in Los Angeles. On the basis of features identified in the review of the four projects, the model makes detailed recommendations on procedures for selecting and training tutors, selecting tutees, and scheduling. It also contains a behavior checklist which identifies methods tutors should use consistently in tutoring sessions. (RT)
