Athletics Online Registration

Athletic Paperwork Online

Online Registration is here!  Starting with the 2020-2021 school year, Chief Sealth International High School Athletics is moving to all online Sports registration using FinalForms, a secure online registration service. 

Switching to FinalForms will help us elevate compliance and safety and will make it easier for you to complete and sign athletic forms from your computer, tablet or mobile device. Plus, FinalForms will save data from season-to-season and year-to-year so you will not need to re-enter the same information over and over! FinalForms also pre-populates common information wherever possible for each of your students, saving time if you have multiple athletes.

You can login ANY time to update information such as emergency medical contacts and changes in your contact information. You will be required to sign your forms once per year and any time you make an update.

FinalForms is our new sports online registration system that completely replaces the paper packet.

Please register here:

Once you are on the FinalForms home page, follow the prompts to create your account, manage your student/athletes and sign your forms.

If you require any support during the process, scroll to the page bottom and click “Use Support”.

Thank you for your participation! We are excited to use FinalForms to increase the safety of our student athletes and their personal information, streamline the registration process for families and staff, and elevate our compliance with city and state athletics.
