The district offers a variety of clubs, activities and sports.
Music
Mount Union participates in competitive marching band in the Tournament of Bands Circuit. The group has earned much recognition within the circuit for numerous competitive victories. Additionally, the band has performed in highly visible parades such as: The West Virginia Strawberry Festival, New York City Veterans’ Day Parade, and the Washington D.C. Centennial Parade for the Boy Scouts of America.
Additionally, Mount Union was formerly home to a County-Wide Indoor Percussion Ensemble, known as Darkhorse Percussion, which hosted students from across Huntingdon County. Since 2022, the unit has been hosted by the Juniata Valley School District because Mount Union no longer saw fit to officially support the ensemble despite not having supported it for several years.
