Enrolment happens in the Summer term for the sacraments of Confession and Holy Communion for children in year 3 of Primary school or older. This is in response to an invitation at Mass and in the newsletter. First Holy Communion takes place in May of the following year. Children are eligible provided they have been baptised. At least one parent must be a baptised Catholic attending Sunday Mass regularly at this church.  St. Aidan’s Catholic Primary school has children from Old Coulsdon as well as a few from other parishes. Children who attend St. Aidan’s School must be enrolled in the parish where they live.

A team of catechists prepare the children in monthly sessions that take place in the church Hall on Saturdays late afternoon beginning in September.
