The International Thespian Society, a division of EdTA, is an honorary organization for high school and middle school theatre students. There are ITS troupes at more than 4,900 affiliated schools around the world. The Society’s mission is to honor student achievement in the theatre arts. Students earn induction by participating in an affiliated school’s theatre program and accumulating points based on the quality and quantity of their work in theatre. Points must be achieved in both performance and technical theatre. High school inductees are known as Thespians, after the first actor.

At Mercy, ITS fulfills one's club credit. The Mercy ITS troupe act as leaders in our theatre community.  ITS organizes fundraisers, Halloween events including the annual Haunted House, a Christmas party and more!
