The use of Student Mobile Phones are banned in all public schools. Bringing a mobile phone to school is discouraged. If mobile phones are brought to school, they are to be handed in at the office from the time of the student’s arrival at school, until their departure from school. The school cannot accept any responsibility for theft or loss of mobile phones brought onto school grounds. Students who are found to bring phones to school and not hand them in will have phones placed securely in the office and returned at the end of the day.
