Uniform Expectations

Our school uniform is a symbol of our Catholic learning community. It is supported by the parent community and School Board policy. The expectation is that our school is a disciplined environment and that our dress uniform is worn with pride and respect. Therefore our uniform must be worn at all times during the school day.

The expectation is: IN SCHOOL, IN UNIFORM.

Uniforms should be clean and in good condition. Students will not modify or accessorize the uniform. All uniform parts must be from our official uniform supplier, McCarthy's School Uniforms.
