Summary:
ZIP code 99345 has one listed school, Paterson Elementary School, serving students from kindergarten through eighth grade in the small Paterson area. With 134 students, it is a small-school setting, so grade-level percentages and year-to-year changes can shift noticeably when the results of a relatively small number of students change.
Paterson Elementary School performed above Washington averages in all three reported subjects during 2025–2026. Overall proficiency was 68.69% in English language arts, compared with 52.81% statewide; 60% in math, compared with 43.11%; and 55.17% in science, compared with 50.95%. The strongest available grade-level results were fourth-grade ELA, at 78.95% versus 50.43% statewide, and eighth-grade math, at 57.14% versus 38.8%. Third-grade ELA was also strong. Some grade-level results were suppressed to protect privacy, so they should be treated as unknown rather than interpreted as low performance.
Parents should also consider the school’s recent direction. Compared with the previous year, all-grade proficiency declined by 7.45 percentage points in ELA, 10 points in math, and 13.58 points in science. Science is the main area to monitor because its current advantage over the state is relatively small, and fifth-grade science was slightly below the statewide average. Even so, the school remains a strong performer overall, with an 11.1-to-1 student-teacher ratio and a highly rated Paterson School District, ranked 21st of 238 Washington districts. Its school ranking has slipped in recent years, however, so families may want to ask about plans to address recent declines, particularly in science and selected math grades.
