St Mark's School is an integrated, co educational, full primary school, providing education with special character, for children from Years 0-8. There is a maximum roll of 245 girls and boys, aged from 5 to 13 years and has a decile rating of 10. Students tend to come from a wide range of socio-economic backgrounds and demographically are enrolled from the wider Christchurch community.
The key element is the association with the Anglican Church, which has been maintained since it became independent from St Mark's Anglican Church in 1981. Today the pastoral care and link between the school and the church is just as strong. A sense of family and community values is not only taught, but practised and experienced.
