Online Athletics Registration

HPS Athletics provides online registration through Family ID, a secure registration platform that is a user-friendly way to register for athletics. When a family registers through Family ID, the system keeps track of information in their Family ID profile, which allows information to be entered one time for multiple seasons, multiple family members, and multiple programs.

The system is mobile friendly, which allows registration to be completed on a smart phone, although most individuals find creating the initial profile on a computer more convenient, It is recommended that initial entries be completed all at once. 

Families without access to a computer are welcome to visit their school’s main office, where they can use a school computer to complete the process.
