Wachter Junior High School opened in 1968, with add-ons in 1969, 1970, 1988, and 2012. Ten acres of the property were donated to the district by the Wachter Trust.
In 1991 Wachter became Bismarck's first middle school and the first fully implemented middle school in North Dakota.
From 1992-1996, Wachter was a Carnegie Bridges School. The Bridges Project was designed to help North Dakota school districts transition from the junior high to the middle school system as well as improve student educational experiences.
Wachter Middle School, serving as a model school project, hosted many visitors from throughout the state and region that were considering the middle school concept.
