Parent training as a service delivery model for 12-month programming is discussed. Legislation, litigation, and research concerning 12-month programming and parents as program implementers for handicapped students are reviewed. A parent training program is described, and results of a study using the program as a 12-month service delivery model showed less regression, shorter recoupment time, and increased skill levels for handicapped students over the summer break in programming. Comparison with students who did not have 12 month service delivery indicated more regression, a longer recoupment time, and fewer increases in skill levels. (Author/CL)
