Important Information to Know Before Registering:

• Students must have a valid sports physical on file to register.  If the physical on file expires before the end of a season, you will need to obtain an updated sports physical. 
• Sports Physicals can be emailed to TBrownlee@isd12.org. Please note it may take up to 24 hours to update the system.
• Parents can check the status of a sports physical date in Campus Parent Portal.  Navigate to “More”, Click on Athletic Eligibility and the most recent physical date will be listed. Sports physicals are good for 3 years from the date of the visit and must be valid throughout the entire season you wish to participate in.  If a date is not listed, a physical is not on file.
• Parent Portal is required to access activity registration. Student Portal does not have access to registration.  Steps on how to register can be found on our website. https://highschool.isd12.org/athletics-activities-at-chs/registration

• Allow for about 10-15 minutes to complete the required forms (Eligibility Brochure, Activity Participation and Transportation Waiver).
• Students are unable to participate in practice and/or tryouts until the online registration is complete and the activity fee is paid.
