CCS had made adjustments to the uniform policy for the 21-22 school year. Please take some time to review this policy. Here is a link to the policy, uniform policy.

Please note that while uniforms are no longer required to be from Flynn and O’Hara, CHS students are still required to wear the color blue with khakis or sweatpants during PE days. Hooded sweatshirts should not be purchased, as they are not a part of the approved CHS uniform. A quarter-zip or non-hooded sweatshirt is allowed to be worn.

Transportation is handled by your local district; please reach out to them with any questions or concerns. If you have not received your student’s bus information from your home district it could be because you did not complete the required Act 372/Request for Transportation form.
