The article presents the growing interest in private schools, including the Catholic ones. The qualitative research conducted shows factors influencing this phenomenon. Catholic schools offer a certain model of relations among teachers, students and parents. The method of teaching is based on Christian personalism that provides individual attention to each student. These institutions are also characterized by a high level of education, which makes them attractive not only for ‘church goers’. Parents play an important role in Catholic schools, they are invited to take part in school management, which makes them partners rather than supplicants at school. In addition, the school management is trying to create opportunities for parents to get to know each other, therefore educational consistency between home and school is built. The type of religiosity handed down is more focused on community spirit and helping others, rather than maintaining strict rules and prohibitions.
