A new stone building was made for the Big Horn Academy in 1916. In 1925 the name was changed to the Cowley High School. The mascot of the school was the Jaguars. The Cowley High School remained in the Big Horn Academy building until 1983, when the last class was graduated from Cowley High School. There were only six students in the class of 1983. Because of the small number of students, the school in Cowley was closed. Beginning in 1984, the town's students began attending the consolidated Rocky Mountain High School in Byron, Wyoming.
