The ways schools shape their (religious) identity may change over time. Because of developments in society and individualization of religion, the formal identity of schools in the pillarized educational system of the Netherlands is not completely representing the religious identity of teachers anymore, nor of pupils and their parents. Religious schools make their own decisions regarding the way they shape their religious identity. However, we lack information on how they actually realize this nowadays. This contribution describes an empirical study on how Dutch Protestant primary schools position themselves in relation to the cultural and religious diversity in society.
