Sunday school tuition forms an integral part of the spiritual care of the children of the New Apostolic Church. Lessons generally take place after the Sunday morning divine service. A child's Sunday school career spans a four year Sunday school course, a three year Religious Instruction course and a one year Confirmation course which run consecutively. The lessons in each syllabus have been expertly designed to meet the needs of the developmental stage of the children in each course.The content of each lesson is scripturally based with a contemporary application so that the children are able to experience their faith.

Teachers are appointed according to the needs of each congregation. They ensure that in addition to the formal Sunday school lessons, a wide variety of informal activities (such as outings) are undertaken. During these activities the children strengthen the child/teacher relationship and the fellowship with their peers.

The foundation for future musical development is laid into our children. All children are exposed to choir singing in Sunday school, and are also encouraged to learn to play the recorder. Further progression to the playing of an orchestral instrument is thereby promoted. Children's choirs sing in divine services and on various other occasions.
