Each year, Greenhills holds Convocation for students on the last day of the first week of school. It is a time to gather together in community in order to formally appreciate and recognize the senior class as they move into the position of being leaders in the school. Seniors sit on stage, facing their 6th–11th grade peers, with several of them speaking to the school about the upcoming year and its many opportunities. This event is also being live streamed at greenhillsschool.org/convocation2025.
