The presentation discusses how different models of learning religion promote respect for the right to freedom of religion or belief. Three different models of learning about religion are offered in Estonian schools: there are schools with no Religious Education, others have inclusive Religious Education, and there are also religiously-oriented schools with a confessional approach to teaching religion. The article draws on data of the research done in the framework of REDCo project (the main project 2006-2009, replicative study in 2012) and also CARDIPS project (2014). The research projects studied students' views about how they see religion in education. The samples consist of students from different Estonian regions and different experience of learning about religions. Their attitudes to two questions are studied. First, how do students differ in their own attitudes about the need to respect a person who is of a different religion? Second, what do young people think about religious freedoms in the school context? The results of the study call out for discussion of practicing religious freedom in school and practices what may best contribute to a tolerant society.
