Mount Si High School 2021 Graduation Slideshow & Highlights


This year, 456 seniors in the Class of 2021 earned Mount Si High School diplomas. Due to COVID safety requirements, the school’s 77th Graduation was conducted in-person through three ceremonies on Friday afternoon, June 18, 2021. This approach enabled the school to celebrate the students in person, while limiting crowd size with fewer grads and guests, and adhering to public health school safety requirements. Students selected the ceremony time they wanted to attend (at 2 p.m., 4:30 p.m. or 7 p.m.) and could sit with a friend with whom they wanted to walk. In addition, all three events were livestreamed.  


Below, enjoy a slideshow, links to the ceremony videos, and some Class of 2021 highlights shared by Mount Si High School Principal John Belcher.
