The correlation of student teachers' religiosity with their views on the religious education course that they are called on to teach in Greek public schools is the subject treated in the present survey. The five main features of religiosity, that is, (1) religious faith, (2) religious knowledge, (3) religious experience, (4) participation in a religious group or community, and (5) daily practice and conduct, were assessed for 1009 student teachers. With the help of data processing and cluster analysis, a causal relationship was found between their religiosity and their views on religious education. (Contains 9 figures, 1 footnote, and 7 tables.)
