Criminological studies of contextual effects on adolescent offending have focused either on residential areas (considering effects of characteristics like disadvantage and collective efficacy) or on school characteristics (studying effects of organisation and social climate, for example). However, adolescents are simultaneously exposed to multiple contexts, and the influence of these contexts on their lives should be studied simultaneously rather than separately. The principal subject of this contribution lies in analysing to which extent there is unique neighbourhood level variation and unique school level variation in adolescent offending, and in two major and stable correlates of adolescent offending, morality and low self-control. Data are used from the Study of Peers, Activities and Neighbourhoods (SPAN), with 612 adolescents in various schools and neighbourhoods in the Netherlands. The results show that there is no unique neighbourhood level variance anymore after controlling for unique school level variance, while some variation at the school level still remains with regard to self-control and morality.
