From the Cranbourne Carlisle Uniform Policy:
Parents are reminded that stud earrings and sleepers worn in the lower earlobe are the only acceptable jewellery to be worn to school. Watches are permissible upon parent approval. No responsibility is accepted by the school.
In an effort to prevent jewellery-related injuries from occurring during physical education, we request that no jewellery at all be worn on the days that children have PE. If earrings must be worn, please ensure that they are small studs only.
