Spring Sports - Crystal Lake South High School (IL)

It's that time of year again! We are excited to have your student interested in participating in

athletics for the 2025-2026 school year.

Due to Arbiter purchasing the rights to Rschool, we need to update our registration process for athletics. Below you will find information on how to register with the new program.

Each Registrant needs the following:

Create a NEW account in the new system, your Rschool account is no longer active.
Parents/Guardians of student-athletes intending to participate in athletics MUST complete their online registration.
Upload students’ most recent physical to ensure eligibility for participation.

Please follow these steps:

Create an Arbiter Registration account (you only need one account for your whole family). You may create your account by clicking here.
Activate your Arbiter Registration account using the activation link that will be automatically sent to your email. (Note: this email may go into your junk folder).

• If you are having trouble creating your account, receiving the activation email, or logging in, you may contact support at registration@arbitersports.com or call at 800-311-4060.

confirming we have received your registration.
