Three documents describe the Project Success Environment Program, which was funded to help alleviate behavioral and academic problems of children from urban, low-socio-economic backgrounds by providing them with an opportunity to experience success in school. The program, sponsored by the Atlanta Public Schools, consisted of: (1) a positive contingency management system designed to deliver a high rate of reinforcement for appropriate social and academic behaviors, (2) a classroom arrangement designed to foster small group and individualized teaching, and (3) some revision of the standard curriculum. The three-part program, referred to as the "success technique," was tested in 44 classrooms over the three year period and resulted in dramatic improvement in classroom management and substantial achievement gains. A detailed summary of the project is presented in "An Overview of Three Years Happenings," which chronologically reviews project developments and changes as well as initial efforts to spread the technique to other schools. The "Toomer Log: A Blow By Blow Description of Applying Positive Reinforcement" presents a condensed version of the practical difficulties and day-to-day implementation procedures. A third document, "A Positive Contingency Management Program for Elementary Teachers," describes the method and results of the program's third year. (Author/KSM)
