Summary

International School is a public 6-12 school serving about 600 students in the highly-regarded Bellevue School District, and it currently holds the #1 ranking out of all 438 schools in Washington state.

It excels across all subjects, with over 84% of students proficient in math, English, and science, outperforming other top local schools like Mercer Island High School and Newport Senior High School.

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
