Summary

Northwood Elementary School is a highly-rated public elementary school (PK-5) serving 398 students within the top-ranked Mercer Island School District in Washington.

Academically, Northwood is an excellent school, consistently earning 5-star ratings and performing well above state averages, with recent proficiency rates over 75% in English and Math. It's important to understand its performance in context: while Northwood ranks in the top 10% of all Washington elementary schools, it is typically the lowest-performing among the four exceptional elementary schools on Mercer Island, which include Lakeridge Elementary School, Island Park Elementary, and West Mercer Elementary. Interestingly, Northwood spends more per student than these peer schools. When compared to schools in neighboring districts, Northwood outperforms many, such as those in the Seattle School District No. 1, but trails some elite schools in the Bellevue School District like Medina Elementary School.

Key insights for parents include Northwood's strength in student growth, with fifth graders performing notably higher than third graders, and its low student-teacher ratio. A point of attention is the performance of its Special Education students, which has seen a significant decline in recent years. Ultimately, Northwood represents the "Mercer Island Effect"—even the district's lowest-performing school is still outstanding compared to most schools statewide, highlighting how district boundaries can shape educational outcomes.
