Many juvenile justice systems are characterized by an amalgam of different principles and ideologies, which have been incorporated into laws and policies regarding youth crime. This study examines the perceptions of youth probation officers (YPOs) concerning the 2003 Youth Criminal Justice Act (YCJA) in Canada, which is one recent case example of a mixed model of juvenile justice. For instance, although the Act emphasizes diversion and community-based sanctions for first time and minor offenders, it also allows for adult-length custody sentences for the most serious and violent youth. This study asked YPOs about their understanding of the YCJA and their ability to apply the Act in their daily work as well as their access to community programs in 2004 and 2007. The results as well as previous research on the YCJA and policy implications are discussed. (Published Abstract)
