Online CMS sports registration now through Arbiter
Colonial Middle School will be moving all athletics registration to Arbiter for the 2026–2027 school year. Rather than a disruption, this is an upgrade, and families can expect the same trusted experience they've come to rely on, now backed by an even more robust platform.
What does this mean for you?
- All sport registrations for 7th and 8th grade student-athletes for the 2026–2027 school year will now be completed through Arbiter.
- Below you will see additional communication with step-by-step instructions on how to create your family account and register your student for their sport(s) of interest.
- Arbiter's platform allows for easier management of required documents, emergency contacts, and eligibility information.
Our athletics office as well as Arbiter will be available to assist any family that has questions or needs support navigating the new system. Thank you for your continued support of Colonial Middle School Athletics. We look forward to a fantastic 2026–2027 season!
