Centralia High School was built in 1909. The current Centralia High School building is the second to bear the name. It was built in 1969, the first senior class graduated in 1970. In 2017, voters in Centralia passed a $74 million bond that will allow for the complete remodel and modernization of Centralia High School in two phases—-Phase 1 and Phase 2. The first Phase of construction (which includes the library, math, English, social studies, special education, most science classrooms, and the main office) will be complete and occupied by staff and students in the fall of 2019. Phase 2 is scheduled to be completed in March 2020 and will include the instrumental and vocal rehearsal rooms, art department, wood shop and metal shop, commons, and performing arts center. The entire building is set to be completed by the fall of 2020.
