Summary

Southgate Elementary School is a K–5 school in Kennewick, Washington, serving 416 students in the Kennewick School District. The school ranks in the 53rd percentile statewide, with three stars, and has shown notable recent improvement. Its ranking rose from the 28th percentile in 2023–2024 to the 48th percentile in 2024–2025 and then the 53rd percentile in 2025–2026. Southgate is currently fourth among the nearby schools provided, just behind Hawthorne Elementary School and ahead of several other local schools.

Math and science are Southgate’s strongest academic areas. In 2025–2026, 53.88% of students were proficient in math, compared with 36.83% in the district and 43.11% statewide. Science proficiency reached 56.72%, the highest among the nearby schools listed and slightly above Sage Crest Elementary. Fifth-grade math was particularly strong at 62.69%. Southgate’s 41.06% ELA proficiency rate, however, was below both the district and state averages. Third-grade ELA was the clearest weakness at 24.24%, while fourth- and fifth-grade results were considerably stronger. By comparison, Lincoln Elementary School and Sage Crest posted stronger overall rankings and ELA results.

Southgate’s 54.57% free-or-reduced-price lunch rate indicates a moderately high level of economic need compared with nearby schools, and its 13.9-to-1 student-teacher ratio is competitive locally. The school’s low socioeconomic-status subgroup ranked in the 68th percentile, an encouraging sign that recent gains extend to economically disadvantaged students. A major area for follow-up is special education, whose most recent available subgroup ranking was at the 6th percentile, far below the school’s overall standing. Overall, Southgate appears to be a rapidly improving school with clear strengths in math and science, but continued work is needed in reading—especially third grade—and special education outcomes.
