Summary

Newcastle Elementary School is a public PK–5 school serving 451 students in Newcastle, Washington, a suburban community in the Seattle area. It belongs to the highly ranked Issaquah School District, which ranks 3rd among Washington’s 238 districts. Newcastle is a consistently strong school academically: it ranked 66th out of 1,138 Washington elementary schools in 2025–26, placing it in the 94th percentile statewide, and has earned a five-star SchoolDigger rating. Its student-teacher ratio was 15.6 in 2024–25, and per-student spending was $20,619 in 2023–24.

Science is Newcastle’s clearest strength. In 2025–26, 88.16% of students were proficient in science, compared with 78.36% in the district and 50.95% statewide. Math proficiency was also strong at 79.82%, above both the district’s 75.78% and the state’s 43.11%. English language arts proficiency was 75.44%—well above Washington’s 52.81%, though 3.60 points below the district average. Results are especially impressive in 5th grade, where proficiency reached 89.47% in ELA, 84.21% in math, and 88.16% in science. By comparison, Newcastle slightly outperformed nearby Apollo Elementary School overall and was close to Hazelwood Elementary School; Newcastle’s largest advantage over both schools was in science.

Newcastle also substantially outperformed most nearby schools in the Renton School District, including Maplewood Heights Elementary School, Kennydale Elementary School, and Hilltop Heritage Elementary School. The notable nearby exception is Somerset Elementary School, ranked 3rd statewide and significantly higher in ELA and math. Parents may want to monitor Newcastle’s recent ELA decline—particularly in 3rd and 4th grades—along with variation among low-socioeconomic-status students and older special education results. Even so, its strong mathematics, outstanding science growth, and consistently high statewide ranking make it one of the strongest schools in the area.
