Activities & Athletics Registration

Students register for sports and activities online. The registration system has moved to a new platform called Affinety for the 2026-27 school year. All families must create a new account and add their students in the new system before registering. The following steps only need to be completed once before registering.

How to Create an Account in Affinety

Sports Physicals

Sports physicals are valid for three years. Please turn the MSHSL Medical Eligibility Form in to the Activities Office.

Affinety will not allow registration if the sports physical is more than three years old or if it is set to expire during the season for which you are registering.
