This article is an abstract of a suggested methodology for comparative studies in religious education. It is based on a study where religious education in state schools in England and Norway were compared. The methodology is a synthesis of two sets of ideas. The first is an idea of three dimensions in comparative education: supranational, national and subnational processes. The second regards levels of curriculum: societal, institutional, instructional and experiential. I exemplify how this methodology can be used by referring to my particular study, but also suggest ways of developing it for further uses.
