The resource used at St Thomas More school is 'A Journey in Love' which is a developmental programme for primary children written by Jude Groden.

A Journey in Love has as its foundational premise the belief that we are made in the image and likeness of God and, as a consequence, gender and sexuality are God's gift, reflect God's beauty and share in the divine creativity.

In order that children may grow and develop healthily and holistically towards an understanding of their gender and its implications for successful relationships, they must be at ease with themselves and grow in self knowledge.
