The International Thespian Society (ITS) is the only theatre honor society for middle and high school students in the country. ITS recognizes, rewards, and encourages student achievement and celebrates the work of students in all aspects of theatre – performance and production. Each student is honored on a national level and gains access to opportunities and resources beyond those of their school.

The students of Troupe 2221, Mountain View High School's chartered Thespian troupe, join over 2.4 million students who have been inducted into the International Thespian Society since 1929.
