Making predictions about the possible delinquent behavior of youth may be harmful to the children involved. The breadth of the concept makes specific predictions difficult. An interpersonal maturity classification provides some definition to the scope of this conflict by classifying youth according to cognitive and maturity factors. Another delinquency perspective separates behaviors according to individual perception and internalization of social rules and to individual abilities to perceive the views of other people on diverse topics. A third view of delinquency considers differences in family childrearing effectiveness as a classification mode. Teachers interested in using these systems must first recognize the unique individuality of each child. These theories can be useful in helping educators understand the backgrounds, history of delinquent behavior, frustrations, and perceptions of predelinquent male youth. Labeling a child as delinquent or predelinquent is not necessary in order to focus on changing negative behavior. Sixteen references are included.
