Summary

Northwood Elementary School is a public prekindergarten–5th-grade school in Mercer Island, Washington, serving 398 students in a community known for excellent schools and convenient access to nearby Bellevue and Seattle. The school benefits from the highly rated Mercer Island School District, which ranks first among Washington’s 238 districts. Northwood received a five-star rating and ranked 59th out of 1,138 Washington elementary schools in 2025–26, placing it in the 95th percentile statewide.

Northwood’s 2025–26 proficiency rates were 72.73% in English language arts, 75.14% in math, and 84.91% in science—well above Washington averages in all three subjects. Science is the school’s clearest strength: results have remained around 83–85% in each of the past three years and slightly exceeded the district average. However, Northwood trails nearby Lakeridge Elementary School and Island Park Elementary School in ELA and math. It is competitive with Newport Heights Elementary and stronger than Enatai Elementary School in all three reported subjects. Northwood also outperformed nearby Seattle schools such as Hawthorne Elementary School, Orca K-8 School, and Graham Hill Elementary School.

The main academic concern is fourth grade, where ELA proficiency was 65.38% and math proficiency was 64.29%, considerably below district results. Overall ELA performance has also declined from 85.00% in 2023–24 to 72.73% in 2025–26, while math remains strong but below its recent peak. Northwood’s 15.0-to-1 student-teacher ratio and $21,645 per-student spending were favorable compared with several nearby Mercer Island schools. About 10.3% of students were eligible for free or reduced-price lunch, somewhat higher than at Island Park Elementary School and Lakeridge Elementary School. Parents may also want to ask about support for special education students, whose statewide effectiveness ranking was near the middle, while recognizing that Northwood remains a strong school overall.
