Babcock Field was overflowing with family, friends, faculty and staff last night as 92 seniors gathered to be honored with diplomas and officially conclude their time as Polytechnic School students. Hale Integrity Prize recipient Michael Yen offered the invocation, after which Head of School John Bracker welcomed the seniors and their families and friends. This year’s commencement speeches were delivered by the seniors themselves. Eight students were randomly selected to deliver speeches telling the stories of their Poly experiences. Head of Upper School Jennifer Fleischer then presented the class. After diplomas were awarded, Faculty Appreciation Award recipient Dinh Nguyen offered the benediction before Bracker concluded the evening.
