An operant conditioning program for 12 problematic adolescent boys is described in detail. Complete procedures are discussed, including criteria for student selection and the Programming Interpersonal Curricula for Adolescents (PICA) academic and psychological test battery. The academic component of the program focuses on mathematics and English language. Both individual programmed materials and classroom experiences are utilized. A series of interpersonal skills classes deals with the development of behavior useful to students both in school and at home. General elements of the study program are examined: (1) the reinforcement schedule for successful performance; (2) the requirements for advancing through the program; and (3) an explicit detailing of the data management procedures. Students attend PICA only in the morning and return to their regular schools in the afternoon. A school liaison program, designed to co-ordinate the two, is described. A substantial section of the report deals with the parent training program which is divided into two parts: (1) setting behavior standards; and (2) contingency management procedures. All materials and instructional procedures of this parent program are elaborated. Addenda include: (1) PICA forms to report student status and progress to schools; (2) selections from the student handbook; and (3) selections from the PICA "parents newsletter." (TL)
