A typical high school graduation ceremony lasts between 1.5 to 2.5 hours. In some cases, especially with larger graduating classes or more elaborate programs, it can stretch up to nearly three hours. The ceremony usually includes a processional, speeches (from valedictorians, administrators, and others), and the calling of each graduate's name one by one. Several factors influence the length, such as the number of graduates, the number and length of speeches, special performances, venue logistics, and how the names are read. On average, guests can expect to spend about 1.5 to 2 hours witnessing the full ceremony.
