The Atlas is an interdisciplinary project focused on the rights of religious or belief minorities (RBMs) in 16 EU countries through 5 policy areas: legal status, education in public schools, religious or belief symbols, spiritual assistance and family law. By analysing data on the policy area 'Education in Public Schools' in a comparative way, this paper discusses the place of religion in different education systems in Europe. Which religions are taught in schools? Who decides the curricula? Who pays the teachers? Are RBM representatives satisfied with the system of teaching religion(s) in their country? To tackle religious illiteracy and discrimination linked to religions and its members, it is important to know how the religious factor is dealt with in schools; from this point of view, the results of the Atlas stand as an important analytical and reflective tool for students, teachers and policy makers.
