He created the position of school chaplain, an important pastoral presence for the youth, by assigning a special priest to each school,

"Among the many ministries in the Piarist Community, there will be the confessor, who will attend to the confessions of the students, and who, with charity and kindness, will attract the hearts of the young people to God, so that all will honor and love Him as a true Father.

You will be able to organize in the schools an assigned confessor who does not teach any classes.

If it is possible, priests should lead the students in continuous prayer. And all the students should participate in groups of ten or twelve, in the morning and in the afternoon and during the class time...The assigned minister will teach the small children how to prepare themselves to receive the Sacrament of Penance and will instruct the older ones about the Eucharist. Ans as much as it might be possible, the students should learn an easy way of praying and other things suitable to their capacity."

Calasanz was the first founder os a Religious Order specifically dedicated to teaching. While the Benedictines, Dominicans and Jesuita, among pthers, were engaged in educating children it was one of the several ministries they exercized. Only the Jesuits had, in the time of Calasanz, more schools in Europe and on other continents than the Pious Schools had during the best times of its expansion. But no other Order was founded with the concrete goal of educating children, especially the poor.
