Parents’ Association
The Parents’ Association organises school activities and is another link between the parents and the school. Meetings are advertised in the newsletter. They meet at 7pm on the second Tuesday of each term except term one when they meet in week 4. New members are welcome.
The chairperson is Mrs Louise Purdon.
Care Network
The purpose of the Care Network is to coordinate and support St John’s Girls’ School families and staff in times of genuine need. This builds on the values of the school. The aim is to build on the positive relationships, work together and help each other whilst respecting confidentiality, to help people with the little things, as well as the big.
The SJGS Care Network Committee is a sub group of the SJGS PTA: Liz Doherty, Ange Pope, Rachel Fleming, and Sarah Bohm. They can be contacted here.
