A community-based program for youths in trouble, Achievement Place is a home-style training setting for pre-delinquents established on a token economy in which the boys earn various privileges by engaging in desirable behaviors that are seen as necessary for their eventual rehabilitation. Five pre-delinquents from Achievement Place attended a special summer school mathematics class where study behavior and rule violations were measured daily for each boy. The boys were required to take a "report card" for the teacher to mark. The teacher simply marked "yes" or "no" whether a boy had "studied the whole period" and "obeyed the class rules." All "yeses" earned privileges in the home that day but a "no" lost all privileges. Using a reversal design, it was shown that privileges dispensed remotely could significantly improve classroom performance. The study has been replicated in the public school, and the technique appears to be very effective as well as practical. (Author)
