Mobile phone policy

Provided by the school and not part of our review

Students may only access their phones with express permission of a staff member and for a specific and temporary purpose. In all other circumstances, when a student's phone is on show, it will be confiscated and passed to the main office, where a record will be kept. Persistent concerns will be referred to the relevant pastoral lead. The school reserves the right to confiscate potentially dangerous equipment for up to half a term and to request that a parent attends school to collect the item at the end of the confiscation period.
