The current study investigates two types of cultural diversity approaches at school, namely (1) fostering equality and (2) promoting cultural pluralism. Adopting a mixed-methods design, this study assesses teachers' (n = 207) and students' (n = 1,644) self-reported perceptions of descriptive norms and evaluates school practices and artefacts in the physical and virtual environment of 22 secondary schools in south-west Germany. Results showed that in all schools under investigation teachers and students perceived descriptive norms fostering mostly equality. A wide variety of practices and artefacts was found, revealing a third distinct cultural approach leaning towards endorsing the majority culture. Different practices and artefacts were linked to an emphasis on equality, cultural pluralism, and endorsing the majority culture. Implications for educational policy, as well as applied diversity research, are discussed. (C) 2016 Elsevier Ltd. All rights reserved.
