Registration

Highline launched a new athletics portal called FinalForms for families to complete and sign athletic participation forms for students in May 2021

FinalForms saves data from season-to-season and year-to-year, meaning you won’t need to enter the same information twice. It also pre-populates information wherever possible, for each of your students, saving you time.

You may review your data at any time to verify it is current. You will be required to sign your forms once per year and after any update.
