The advantages and disadvantages of a 60-day probation training center are discussed. An initial assessment period is deemed necessary to determine if adult candidates for the training center can withstand daily stresses; and a contract system is used to insure focus upon clear objectives for each individual during the 60-day program. The major therapeutic tool used is small group interaction to enable clients to gain more understanding and self-control. Program aspects that aid behavior modification include social skills training, planning for employment, literacy classes and creative activities. The offenders' participation in governing and assisting in the center's daily routine, as well as close involvement with probation officers in small group sessions, are also designed to change offenders' attitudes and maintain behavior improvements in the community after completion of the day center training program. The Ilderton Motor Project, which is also managed by the Inner London Probation and Aftercare Service, is a motor club in which juveniles with persistent driving offense records are integrated with nonoffenders in car maintenance training and in a strictly supervised demolition derby racing program. Through association with nonoffenders, individual and group counseling, and 'directive straight talks,' the juvenile driving offender is exposed to other social values and settings not requiring a car for status within the group. Continued enrollment by the offender in the program is contingent upon continued good behavior under a contract system. It is concluded that the program's steady development and the low recidivism rate of its participants are indicators of success. One reference is provided.
