School Uniforms

Notre Dame de Sion provides a dress code to promote an atmosphere conducive to learning, enhance personal pride and dignity, and project a positive school image to the community. The dress code helps us focus on the essential tasks at school, teaching, and learning. Students demonstrate their commitment to school spirit and community by following the uniform expectations.

For middle school and high school students, dress uniform is worn on special occasions, including all school masses, specific field trips, and ceremonies. Other special dress days are set aside once a season for athletic teams, clubs, cheer, and dance teams and other student organizations.
