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 new 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 page will update with a link when athletic registration for the 2023-24 school year is available. This will be a requirement to complete for your student to compete in athletics at Mount Si.
Before beginning registration, please make sure you have the following:
- Completed physical form
- Basic medical and health information
- Insurance company and policy number
- Doctor, dentist, and medical specialist contact information
- Hospital preference and contact information
Still have questions? Please use this FinalForms step-by-step instructional page.
