Legal treatment for juvenile delinquents in Taiwan is based on the Law Governing the Disposition of Juvenile Cases. In recent years, the concept of punishment has been replaced by the idea of rehabilitation in treating juvenile cases. Thus, the Law underwent the amendment for the fifth time in October 1997, and the 42’’ clause of Residential Community-Treatment, which further induced the rehabilitation concept to the legal treatment for juvenile delinquents. This study aimed to research on the Residential Community-Treatment by distributing self-compiled questionnaires to judges and probation officials (N= 140) in district and juvenile courts in Taiwan. Thus better understandings of considerations, current situations and difficulties of the Residential Community-Treatment were gained. While related opinions were collected, subjects of the involved organization members of Residential Community-Treatment (N=109) were consulted for further information. With the understanding of the needs and suggestions of the workers in fields of juvenile jurisdiction and Residential Community-Treatment, related research findings, it was expected to produce a more effective mechanism of Residential Community-Treatment.
