Summary:
The high-school list for Centralia HSD 200 includes one school, Centralia High School, serving grades 9–12 with 887 students. The available results cover 2024–2025 and 2025–2026. The most important finding is that mathematics has the largest average shortfall from the state: in 2025–2026, the school’s average proficiency was 24%, compared with 39% statewide, a 15-point gap.
There is no other listed high school to compare with, so Centralia High School is both the highest- and lowest-ranked school in this list by default. Against the state, English language arts is its relative strength: its 2025–2026 average was 46%, 9 points below the state’s 55%; the math gap was 15 points, and the science gap was 14 points. Grade 10 science is a notable weak spot: proficiency was 25% at the school versus 48% statewide, a 23-point gap.
Results shifted unevenly over time, with the overall comparison becoming less favorable: the average gap across reported results widened from 10 points in 2024–2025 to 13 points in 2025–2026. The math gap grew from 12 to 15 points, while the ELA gap edged from 8 to 9 points. Not every result fell: grade 9 ELA rose from 54.5% to 55.4%, and grade 9 math rose from 21% to 24%; grade 10 science fell from 36% to 25%. SchoolDigger’s ranking history also declined, from the 53rd percentile in 2023–2024 to the 26th in 2025–2026, with its star rating falling from 3 to 1; a separate current summary lists the school at the 14th percentile. Other context includes a 12.2 student–teacher ratio and 64% free/reduced lunch eligible in 2024–2025. In 2025–2026, graduation was 88% versus 90% statewide, dropout was 1.8% versus 2.3%, and chronic absenteeism was 28% versus 24%. With only one school listed, these figures cannot show differences among local high schools.
