Summary:
ZIP code 99022, serving the Medical Lake area, has one elementary school: Hallett Elementary School, which serves students from Pre-K through fifth grade and enrolls 496 students. Because it is the only elementary school in the ZIP code, there is no local school-to-school comparison; the most useful comparisons are with the Medical Lake School District and Washington state.
Hallett’s clearest strength is science. In 2025–2026, 60.27% of students were proficient in science, compared with 50.95% statewide, although the school was below the district’s 64.27%. Fifth grade was the strongest reported grade overall, with 58.90% proficiency in English language arts and 43.84% in math. Fifth-grade ELA and math were slightly above statewide results, while third- and fourth-grade ELA and math generally lagged the state. Across all grades, ELA proficiency was 47.13%, below both the district’s 55.22% and the state’s 52.81%. Math proficiency was 42.62%, nearly matching the state’s 43.11% but below the district’s 46.87%.
The most important concern is the recent decline in performance, especially in math. From 2024–2025 to 2025–2026, math proficiency fell about 10 percentage points, ELA declined 5.55 points, and science decreased only 1.76 points. Hallett’s statewide ranking also fell from the 68th percentile in 2023–2024 to the 49th percentile in 2025–2026, with its rating changing from three stars to two. The school remains around the middle of Washington’s elementary schools rather than among the lowest-performing schools. Families may also want to consider the broader context: 50% of students qualified for free or reduced-price lunch, the student-teacher ratio was 16.8 to 1, and reported per-student spending was $16,950. Overall, science and fifth-grade results are encouraging, while early-grade literacy and especially math merit focused attention.
