The purpose of this study is to search and analyze different logics that operators use in the work of helping juvenile delinquents to break their criminal behavior. New institutional theory is used in this study to analyze the results. The study was conducted through qualitative interviews of six professionals in two municipalities which work with juvenile delinquency. There are two questions that we want to address in this study. The first one is what methods the social workers are using in two middle large municipalities to help youth to brake there criminal behavior. The other question is what logics are behind the social workers work so that juvenile delinquency can break their criminal behavior.This study showed that different programs are used by social workers and that the social workers logics are important in choosing what program or treatment they are going to give the young adults so that they can break their criminal behavior. The result also showed that the social workers in two municipalities work with multiple operators such as schools and police to create a network around the youth in difficult situations.
