The purpose of this study was to identify the different subgroups of students at risk of dropping out of school. The typology was developed based on the three main contexts associated with school dropout risk, namely, the personal, family and school contexts. On the basis of these factors, the clustering results enabled us to categorize at-risk students into four subgroups: (1) the Anti-Social Covert behavior type, (2) the Uninterested in school type, (3) the School and Social Adjustment Difficulties type, and (4) the Depressive type. Moreover, considering all the contexts involved in school dropout, the clustering technique confirms the importance of behavior problems and learning difficulties, while emphasizing the significance of both depression and the family and classroom environments in the development of dropout risk. Students at risk of dropping out of school report many family organisational problems and that they obtain little emotional support from their parents. They also perceive little order or organisation in the classroom. (Contains 6 tables.)
