All people who belong to Interact Club are of high school or secondary school age.
Some clubs emphasize leadership potential or good grades as prerequisites for membership.
Interact, however, is not an exclusive club. The most important credential is that a person wants to join and become a part of a lively group involved in promoting international understanding and serving the community. Clubs come in a variety of types and sizes. No two Interact clubs are alike. Some have as few as 20 members while others have over 200.
