A "triennium" is a period of three years. This term is often used in academic, financial, and organizational contexts to describe cycles, terms, or events that occur every three years. For example, some institutions may have a triennium for their budget planning or project evaluations. In the context of education, a triennium can refer to the duration of certain programs or initiatives that are designed to be reviewed or renewed every three years. This allows for periodic assessment and adjustment to ensure that goals are being met effectively.
