Every spring, the sixteen technical colleges select one of their respective students to become an ambassador and represent the college and perhaps the System. The colleges respectively nominate one student to represent them, and the System recognizes all 16 of them with their nominators and families in a formal event. Selection is based on a number of criteria, including the students' academic performance and activity at the college. The role of the ambassador can vary from one college to the next, but generally, they be asked to speak as a representative of the college and/or of the state. They may help give campus tours, speak to the board of trustees, media, etc.
