Castle Park is a uniform school. For Prep Department pupils this includes a blazer, sweater, tie, tracksuit and games kit. Montessori children wear the School Tracksuit. The uniform is available from a local supplier and other items such as white shirts are standard. The Parents’ Association – the Friends of Castle Park – organise the sale of second-hand uniform on a regular basis. Full details are published for parents in the annual Parent and Pupil Handbook.
