Student Athlete Registration

Family ID is now Arbiter Sports Online Registration.
Student Athlete Registration Opens 30 Days prior to the Sports Season Start Date.

Student Athlete Registration Process

The Marcellus Athletic Eligibility Health Form and the Concussion Permission Form and the Student/Athlete Handbook Agreement Form must be completed online at Arbiter Sports for each season in which a student-athlete competes.  PLEASE READ EACH FORM.

Marcellus Central School District Athletics will continue to offer the convenience of online registration for Athletics through Arbiter Sports Online Registration (Formerly FamilyID).  The registration process needs to be completed within thirty days of the start of each season that your athlete participates in.

Arbiter Sports Online Registration (formerly FamilyID) is a secure registration platform that provides you with an easy, user-friendly way to register for Marcellus Central School District athletic programs, and helps us to be more administratively efficient and environmentally responsible. When you register the system keeps track of your information in your account profile.



Your child needs to have a valid sports physical.  Sports physicals are valid for a period of 1 year plus the remaining days through the end of the month of its expiration. Physicals that expire during the season are valid through the end of the sports season.  Please be sure to send a copy to the school nurse.  Student Athlete Registrations cannot be signed off by the school nurse without a valid sports physical.
