Summary:
Griffin School District has one listed elementary school, Griffin School, serving students from prekindergarten through 8th grade in Washington. With 585 students, a 17.6-to-1 student-teacher ratio, and a five-star district rating, it is a high-performing PK–8 school rather than one campus among several local elementary options. Because Griffin School District includes only this school, school and district results are the same, and meaningful school-to-school comparisons are not available.
Academically, Griffin School performs well above Washington averages overall. In 2025–2026, proficiency was 64.01% in English language arts, 57.18% in math, and 66.39% in science, compared with statewide rates of 52.81%, 43.11%, and 50.95%. Science was the strongest subject overall, led by fifth-grade science at 73.44%. Math was especially strong in the upper grades: seventh-grade proficiency reached 64.79%, exceeding the state by more than 23 percentage points, while sixth- and eighth-grade math also substantially outperformed Washington. English results were strongest in seventh grade at 73.24% and third grade at 68.89%. The eighth-grade ELA result was suppressed, so it should be considered unavailable rather than interpreted as weak performance.
The clearest area to watch at Griffin School is fourth-grade math, where proficiency was 49.23%, essentially equal to the Washington rate of 49.54%. Sixth-grade ELA also had a smaller-than-usual advantage over the state, at 51.67% compared with 48.27%. Even so, the school’s results have been generally stable: math improved slightly year over year, while ELA and science declined modestly. Its statewide standing also improved, rising from the 68th percentile in 2023–2024 to the 76th percentile in 2025–2026. For families considering this area, the available data point to a strong, improving school with notable strengths in science and middle-school math.
