Graduation happens when you successfully complete an academic program, like high school or college. Then you go to a graduation ceremony.
Scientists might talk about the graduation lines on beakers and rulers that mark out units of measurement. But when most people hear this word, they think about finishing school. Students and their families celebrate graduation from high school, college, training programs, and even kindergarten. At graduation ceremonies, people often wear funny tasseled hats and long robes, then walk up one by one to get an official diploma or certificate.
