Hilo High school has several commencement traditions that stretch back to the school's first graduation in 1909. The graduating class recites a variation of Gaudeamus Igitur with lyrics directly referencing Hilo High, and members of the Hilo High School Alumni Association pass out a lei to every graduate. This latter tradition is attributed to the patriarch of the Tong family, who was among the school's first graduates and supposedly gave a lei to a fellow graduate who was without one during their commencement ceremony. The Tong family also awarded the school's Salutatorian award and trophy with a cash prize until 2003, when the Salutatorian returned the cash prize out of respect for the family's disagreement with the school's current practice of awarding the Valedictorian distinction to more than one student. The Valedictorian trophy is maintained by the Hilo High School Foundation.
