St. Peter’s School was founded next to the Church in 1872. At the time Government regulation stated that if the Church did not provide an adequate school for local needs then the local School Board would step in to ensure such provision. Many Church schools were founded at this time to meet these requirements. Lord Radnor donated the land for the school, as he had for the Church, and the Mayor of Folkestone, Councillor John Hoad, laid the foundation stone in April 1872. The School opened in October the same year. Over 200 people attended the tea and concert held by Father Ridsdale in celebration.
The Church and the School have had close ties ever since. The Vicar is closely involved with the daily life of the school and the Church also provides a Governor. Some of the current School buildings and parking facilities are also leased from the Church. The School uses the Church regularly for assemblies and weekly Mass. In addition, the Church and School combine services for special occasions such as School Sunday, Mothering Sunday or Christingle.
