Carbury School is a primary school reflecting and promoting the ethos and characteristic spirit of the Church of Ireland, Presbyterian and Methodist churches. The school seeks to uphold and express the doctrines, moral teachings, traditions, practices and customs of the above named churches. This distinctive spiritual and moral dimension permeates the core values and daily life of the school.

All pupils are expected to participate fully in the life of the school. Of course, the Board and staff are also sensitive to other traditions and cultures. The programme for Religious Education (a broadly Christian and Bible-based Scheme) devised by the Protestant churches is implemented in the school.

Assemblies are an important time where the school community gathers together. These assemblies may have a religious theme in keeping with the ethos of the school but equally they may cover other themes important to the life of the school.
