Accompanying the rise in the number of working parents is a growing demand for after-school care schemes for children. After-school care schemes, in addition to school, provide pupils with more learning opportunities than the experiences that school provides. The hypothesis is that after-school care schemes offer a better knowledge-basis for learning science than the school and home environments only. This article investigates how after-school care schemes affect learning in grades 5 and 8. While taking into account the socio-economic and ethnic backgrounds of pupils, results indicate that after-school care is of significance. The influence of after-school care is roughly explained by the increased number of learning opportunities. We discuss the implications for research and the limitations of this survey.
