Our students are ambassadors for St John XXIII and wear their correct uniform with pride at all times.
How a student wears the uniform gives a clear message about how the student sees themselves and the school. St John XXIII uniform policy outlines what is acceptable in all matters relating to our school uniform and appropriate personal presentation.
Students in Years 7 to 10 may wear their sport uniform to school when they are timetabled on sport. However, when students are timetabled for PDHPE practical lessons, they must bring their sport uniform to school in their sports bag and change for that lesson.
