Summary:
ZIP code 62801 has one middle school, Centralia Junior High School, serving grades 4–8 with 559 students. With no other middle schools in the ZIP to compare, the clearest picture comes from its results against district and state figures. In 2025–2026, its largest academic challenge was mathematics: proficiency was 9%, compared with 40% statewide, a gap of 30 percentage points.
Centralia Junior High School is both the top and bottom school in this one-school group, so that is not a meaningful school-to-school ranking. Against the state, ELA was its stronger subject: 40% proficiency versus 56%, a 17-point gap; its result was also 2 points above the 38% district result. Mathematics was 9%, versus 13% in the district, or 4 points lower. ELA’s state gap was 14 points narrower than the math gap. SchoolDigger ranks Centralia 962nd out of 1,126 statewide, in the 15th percentile, and gives it 1 star for 2025–2026.
Scores rose from 2024–2025 to 2025–2026, but Centralia did not consistently catch up with the state. ELA increased by 4 points, and its state gap narrowed by 1 point; math rose by 1 point, while its already large gap widened slightly. Science scores rose in grades 5 and 8, but the state gained faster, widening those gaps by 5 and 4 points, respectively. SchoolDigger’s percentile also fell from 31 in 2023–2024 to 15 in 2025–2026, while its rating changed from 2 stars to 1. The student–teacher ratio is 11.5. For 2024–2025, the low-income measure is “All students receive free meals (Community Eligibility),” not a percentage. Chronic absenteeism was 23% in 2025–2026, about 1 point below the state and 3 points above Centralia School District 135. Because this is the only school in the ZIP, the data cannot show how schools compare with one another.
