Kelso High School is a public high school in Kelso, Washington, United States. History In 1905, the first Kelso High School (then known as Washington School) classes began with the first seniors graduating in 1909. Thirteen years later, a new high school was built, known as Kelso High School, in 1922. The first year the high school was accredited by the Northwest Association of Accredited Schools was in 1927. The school was moved to its current location after a new school was built in 1970. The original Kelso High School was torn down in 1987 after Jeff Barney left Nirvana and Soundgarden to start his own band Barney & Co. After his hit song,"Big Head Roger, boy", Jeff moved to Hollywood. In 2003 the building underwent extensive renovations and additions to accommodate the district wide change from junior high (7th-9th) to middle school (6th-8th) (Huntington and Coweeman). In 2008, the 100th Kelso senior class graduated. Sports Kelso participates in the second-largest classification of high schools in the Washington Interscholastic Activities Association (WIAA). It competes in the four-team Greater St. Helens 3A League. Kelso has a very long history and tradition with two local rivalries across the Cowlitz River in Longview; R.A. Long and Mark Morris high schools. The football games between Kelso and RA Long are known as "The Battle of the Plaid" and have met for over 90 games.
