Catechesis of the Good Shepherd (CGS) combines the story of the Good Shepherd with the educational principles of Maria Montessori to take make children feel engaged and understand the importance of the liturgy. Central to this approach is the Atrium, a sacred space prepared for the children. A place of beauty, the Atrium is designed for being with and enjoying God, listening to God’s Word, and praying. At St. Andrew Catholic School, we offer levels one and two Atriums for children ages 3-9 years old.
