Children's religious education is vital for the formation of pupils in Dutch Orthodox Protestant schools. Therefore, it seems self-evident that parents and teachers cooperate. This article presents research on parents' and teachers' opinions about the helpfulness of cooperative practices in religious education. A total of 1346 parents and teachers completed questionnaires developed from a previous study. This article finds that parents and teachers cherish the ideal of 'coherence between school and family' although differences between the respondent groups and school types occurred. Moreover, the research shows that this ideal influences the valuing of cooperative practices of religious education.
