ConVal High School offers students a wide variety of co-curricular clubs and activities. From the Art Club and the ConVal Current, the student newspaper, to ConVal Robotics and the Yearbook Club, the school recognizes a total of 35 clubs and local chapters of civic organizations, such as Interact.
ConVal High School also hosts local chapters of honor societies and national recognition programs for high school students, such as the National Honor Society and Future Business Leaders of America (FBLA).
Some clubs are associated with competitions at the local, state, regional, or even national level. Students are encouraged to become actively involved, both for fun and to supplement academic pursuits. Meetings typically occur after school.
