Summary:
Sunnyside School District serves students from pre-kindergarten through grade 12 across eight schools: five elementary schools, two middle schools, and one high school. The district enrolls about 6,147 students, and reported free- or reduced-price lunch participation exceeds 80% at every school with available data, indicating substantial economic need across the area. Overall, the district ranks in the 7th statewide percentile, so families should view school-level differences as important when comparing options.
Washington Elementary has the strongest overall elementary profile, with the highest elementary ELA, math, and science results; its math proficiency of 32.56% is particularly notable. Outlook Elementary has the district’s best science result at 38.57% and the lowest student-teacher ratio, although its ELA performance is weaker. Pioneer Elementary School made the largest recent science gain, improving by 10.5 percentage points. Chief Kamiakin Elementary School posts middle-range results, while Sun Valley Elementary School serves pre-kindergarten through kindergarten and has no comparable test-score or ranking data reported.
Among middle schools, Harrison Middle School currently outperforms Sierra Vista Middle School in ELA, math, and science, with the largest difference in science. Sunnyside High School has the district’s strongest ELA result at 40.60%, but its math proficiency is only 6.67%, making secondary mathematics the clearest concern. Districtwide, ELA and math declined recently while science improved. Graduation is 80.2%, slightly below the state rate, and the dropout rate is somewhat higher than the state figure. Parents comparing schools should focus especially on math support, early-grade literacy, and the schools’ differing science performance.
