For close to 45 years, Silicon Valley International School (formerly known as International School of the Peninsula and Alto International School) has provided students with a rigorous and dynamic bilingual International Baccalaureate education through its Chinese (Mandarin), French, and German, and now Upper School Language Acquisition programs, guiding students to develop the critical thinking abilities and cultural fluency associated with being bilingual.

INTL has two campuses, located in Menlo Park’s tree-lined Willows neighborhood, and also in a convenient Palo Alto location close to HWY-101.

Early Years Center (Preschool & Pre-Kindergarten), Middle and High School is located on our Willows Campus at 475 Pope Street, Menlo Park

Kindergarten – 5th Grade is located at our Cohn Campus at 151 Laura Lane, Palo Alto

INTL provides an exceptional and nurturing environment for young learners (preschool and pre-kindergarten) and year-round care (which includes a few weeks in the summer) is included in tuition for preschool and pre-kindergarten students.

The school is known for its renowned bilingual elementary school as well as a college-preparatory program in upper school (6th to 12th). For students who do not have previous bilingual immersion experience, we invite families to inquire into our Upper School Language Acquisition program.

INTL is proudly recognized as an International Baccalaureate World School, authorized to provide the internationally-respected Primary Years, Middle Years, and Diploma Programmes for grades preschool to 12th.
