Registration and Forms

We are pleased to announce that Mount Si High School has partnered with FinalForms, an online forms, and data management service. FinalForms works with most of the high schools in Washington State and allows families to complete all of the requirements online. This  tool also saves data from season to season and year to year, meaning that you will never need to enter the same information twice. 

 This will be a requirement to complete for your student to compete in athletics at Mount Si.

  • Completed physical form
