Southside School District

Southside School District in Shelton, Washington, has one listed school, Southside Elementary, serving 208 students from kindergarten through 7th grade. Families will find a small-school setting, a 14.4-to-1 student-teacher ratio, and a district ranked 52nd out of 238 Washington districts, placing it in the 78th percentile with a four-star rating.

Southside Elementary has shown steady improvement in its statewide standing. Its ranking moved from the 45th percentile in 2023–2024 to the 55th percentile in 2025–2026, while its rating increased from two stars to three. Science is the clearest strength: 65% of students were proficient in 2025–2026, about 14 percentage points above the Washington average. Math proficiency was also slightly above the state average overall. Upper-grade performance was encouraging, particularly sixth-grade math, where proficiency was 56.52% compared with 39.79% statewide, and fifth- through seventh-grade English Language Arts, which all exceeded state results.

The main area for improvement is performance in the earlier tested grades. Third- and fourth-grade English Language Arts results were considerably below state averages, and math results in grades 3 through 5 were also below state levels. By contrast, results improved notably in the upper grades, suggesting that families should look at grade-specific performance rather than relying only on the overall averages. English Language Arts improved by nearly three points and science by almost six points from 2024–2025 to 2025–2026, while math remained nearly unchanged. The school also reported $19,996 in per-student spending for 2023–2024 and 44.71% participation in free or reduced-price lunch programs. The seventh-grade math result was suppressed for privacy and should be treated as unknown, not as a zero.
