About international schools in Seattle, United States

Seattle’s international-school options span tuition-free district “International” and dual-language immersion pathways inside Seattle Public Schools as well as private bilingual and independent day schools, so families typically choose between a no-fee public route and fee-paying private programmes. Common offerings include Dual Language Immersion in Spanish, Mandarin and Japanese, International Baccalaureate classes at some secondary schools, and US-style curricula with added world-language strands; small independent schools sometimes run French or other bilingual programmes. Costs vary widely: district DLI places are part of the public system, while private bilingual schools commonly charge in the mid-teens to low-thirties of thousands per year and established independent day schools frequently sit in the high-tens to fifty-thousand-plus range, with additional application and activity fees. Admissions rhythms differ: district School Choice and open-enrolment windows with lotteries (usually in the winter months) control places in International/DLI pathways, while independent schools follow a separate application cycle through common portals such as Ravenna or the Puget Sound Independent Schools consortium and are best started 12 - 16 months before the year you want to begin.

FAQs for United States

What curricula and languages are commonly offered in Seattle’s international schools?
Public International and Dual Language Immersion (DLI) programmes in Seattle commonly provide instruction in Spanish, Mandarin and Japanese, with linked middle- and high-school pathways; International Baccalaureate courses are offered at some secondary schools alongside standard US curricula. Smaller independent bilingual schools may offer French or other language programmes, and many schools combine an American curriculum with strong world-language options.
How much should we expect to pay for a private international or bilingual school in Seattle?
Public DLI and International Schools are part of Seattle Public Schools and carry no tuition, but private options vary a great deal. Smaller bilingual day schools often charge in the mid-teens to low-thirties of thousands per year, while long-established independent day schools commonly charge tens of thousands annually and some competitive schools exceed fifty thousand; families should also budget for application, enrolment deposits, trips and activity fees.
When should we apply if we are relocating to Seattle?
For district International/DLI pathways you must use Seattle Public Schools’ open-enrolment/School Choice process (the district posts exact dates each year but the window and lottery work around winter months), so plan to register as soon as the district’s enrolment window opens. For independent schools, many use shared portals such as Ravenna or the PSIS systems and follow a fall application-to-winter decision cycle; local guidance commonly advises beginning the search and application process 12 - 16 months ahead of the intended start date.
Will a child who starts in a DLI programme be able to continue the same language pathway?
Seattle’s DLI model is designed with continuity in mind: most elementary DLI pathways link to named middle and high-school programmes so pupils can continue study of the same language as they progress. Placement rules and transportation vary by address and pathway, and some mid-grade entries require language proficiency assessment, so check the specific pathway and linked schools before you decide.
What should parents look for when comparing international schools in Seattle?
Focus on how instructional time is split between languages, whether the school guarantees continuation into linked middle or high programmes, teacher qualifications in bilingual education or IB, special-education and English-language support if needed, and the total cost including fees and trips. Also check admissions timing and waitlist practices, opportunities for parental involvement, and whether the school’s curriculum and assessment approach match your child’s needs and your family’s plans for future moves.
