International School

Public Grades 6-12
Summary

International School is a public school in Bellevue serving about 600 students in grades 6–12, in the highly regarded Bellevue School District, an area known for strong schools and high academic expectations. The school ranked first among 438 Washington schools in 2024–2025 and has remained in the state’s top 10 in every reported year since 2017–2018. It also earned five stars in every reported ranking year, showing that its strong reputation is based on sustained performance rather than a single exceptional year.

Academic results are excellent across all three tested subjects. In 2025–2026, 88.3% of students were proficient in English language arts, 83.06% in math, and 89.94% in science. These results were substantially above both state and district rates, with math and science standing out as particular strengths. The school also showed strong middle-grade results: 85.87% of sixth graders were proficient in ELA, 78.26% in math, and 88.04% of eighth graders in science. Among nearby schools, Newport Senior High School had slightly higher ELA results, while Mercer Island High School had higher ELA but lower math and science results. International Community School reported higher ELA and math results in the latest comparison, though its current science result was suppressed.

Families should also note the school’s consistency: across the four most recent reported years, ELA stayed approximately between 88.2% and 89.5%, math between approximately 82.1% and 84.0%, and science between approximately 89.9% and 95.7%. International School’s reported student–teacher ratio of 19.9 is fairly typical for nearby schools, so its results are not simply associated with unusually small classes. Its 8% free- and reduced-price lunch share is lower than at most nearby comprehensive schools, an important context when comparing outcomes. Graduation and dropout figures were not provided, so those measures cannot be compared directly.

Open Quote International school is amazing! I have two sons attending and my daughter will attend in 2 years. They have an amazing curriculum, the teachers are always engaging and the student body is very diverse. I feel very lucky my children have the privilege to attend this school. Close Quote
