Treasure Valley Indoor Association was created in 2017 and rebranded as Idaho Indoor Circuit in 2023.  It is the mission of the Idaho Indoor Circuit to support and promote indoor color guard, percussion, and winds in the state of Idaho. The circuit produces clinics, workshops and showcases that are focused on student growth through the guidance of highly qualified clinicians and adjudicators. Additionally, the circuit is a resource for directors to develop and refine their knowledge about the indoor activity.

In 2019, TVIA, now known as Idaho Indoor Circuit, became a division of Armada Corps, Inc. a 501(c)(3) non-profit organization.  Armada Corps promotes further education in the marching arts and is a member of Winter Guard International (WGI).
