Originally established in 1910, the high school sat between the downtown area of Corvallis and Oregon State University.

Prior to the construction, all grades were housed in Corvallis Central School, which was built in 1889 and was located one block west on 7th Street.

In the 1930s, Corvallis High School had reached a population of 650 students in a structure that was intended for 400.

This allowed the school district to apply for a Public Works Administration grant and loan, which was awarded in January 1934.

In the spring of 2000, after the district finished a seismic analysis of its 17 schools,[7] it was decided that the building was unsafe for student use.

[8] In an effort to save the structure, the building was nominated and added to the National Register of Historic Places in 2003.

The second Corvallis High School structure was torn down in the summer of 2005 and was replaced with a softball field and a parking lot.

The original front parking lot still remains, as well as several auxiliary buildings along Dixon Creek that were built in the 1960s.

This third Corvallis High School building, facing Buchanan Street, was opened in the fall of 2005.

Founded by CHS students in time for the 2002 FIRST Robotics Competition season, Team 997 Spartan Robotics provides a hands-on program for high school students to learn about STEM in a competitive sports-like environment.

Spartan Robotics was ranked fifth in the nation during the 2007 FIRST Championship at Atlanta, Georgia, after winning at both the Portland and Sacramento Regionals.

Team 997 ranked first in the 2010 Autodesk Oregon regional competition, making it to Atlanta for a second time.
