Declo High School

Declo High School's first graduating class graduated in 1927.

The school's colors were green and white until about 1930, when they were changed to orange, black, and white.

Before the spring semester of the 1997–1998 school year, the junior and senior high schools (grades 7 through 12) were taught in a building built in the 1950s in crowded conditions. When the new building was completed, the high school moved there with grades 9 through 12 and the junior high remained in the older building, with grades 6 through 8.

In 2003, the original one room log school house was relocated in front of the high school and restored. Declo graduated its first class in 1927. Originally the schools colors were green and white, but were changed to its present orange and black in the 1930s. The mascot is a hornet. The school fight song melds the choruses from “Stars and Stripes Forever” and “Go, Vandals, Go”, the fight song of the University of Idaho.
