Kelly Walsh High School, which was named after a principal of Natrona County High School, opened in 1965. Several subsequent expansion and remodeling projects have been completed, including the construction of a second gymnasium in 1995. The school started offering instruction to students in grades 10–12 only and continued that for nearly 38 years.

During this closure classes were held across town at Natrona County High School. Classes for Natrona County High School students were held in the morning, while classes for Kelly Walsh High School students were held in the afternoon. Kelly Walsh High School partially reopened for classes during the fall of 1990 and was completely open after the Christmas break in January 1991.
