The Catechesis of the Good Shepherd is a Christian formation process for children aged 3 to 12. It is grounded in Scripture and liturgical study using Montessori principles as a tangible, yet indirect, self-teaching method developed by Dr. Sofia Cavalletti & Dr. Gianna Gobbi since 1954.

The Catechesis is based on the principle that the child desires to draw near to God. The process allows children to hear the Gospel through the use of sensorially rich materials. The children are free to work with these materials that represent essential proclamations of the Christian message.

The adult's task is to prepare the sacred space for the children, called the Atrium, so they can respond to this Holy relationship, first proclaimed to them by Jesus, the Good Shepherd. Themes are offered in such a way as to develop the religious potential present in every child.

The Catechesis is offered in 19 countries and different religious traditions.
