[2] Tri-West was formed from the consolidation of three high schools: Pittsboro, Lizton, and North Salem.

This also caused the formation of the North West Hendricks School Corporation.

In Pittsboro, the original gym remains as part of the elementary school.

It holds grades 9-12 from the townships of Middle, Union, and Eel River.

The school colors are navy blue and vegas gold.
