The Bellevue School District is arguably the most sought after district in the state.  Boasting more top 10 WA schools and more top 100 nationwide schools than any other, it is not surprising that the district has closed borders.  To attend a particular school, you must live in its service area.

Westwood service area schools are:

Elementary - Somerset Elementary

Middle School - Tyee Middle School & International School

International School is available to anyone in the Bellevue District by lottery.  Application is made for admission into the 6th grade, and the program continues through high school.
