Alta High School has an award-winning performing arts program. The Theatre Department won the 5A State Championship in 2012 and in 2013. Alta's jazz band has consistently received high markings in state competitions. As part of the 2017 voter-approved bond, a new Performing Arts Center will replace the current auditorium. It is taller, not within the center of the building, and has twice as much seating as the former space. It is scheduled to open in March, 2020. Alta offers Key Club, the largest international student leadership organization in the world. Alta also offers Art, Anime, Ultimate Frisbee, Polynesian, Latinos in Action, Improv, Drama, Nintendo, TableTop Gaming, Chess, Robotics, Medieval, and Hacker clubs.
