Alto International School believes in the importance of a globally-minded, progressive education.

Alto is an International Baccalaureate World School in the heart of Silicon Valley and is the only school in the Bay Area offering the International Baccalaureate from preschool through high school. Every day we create a stimulating learning environment for our students who come from all over the world. Students of all ages are exposed to an international mindset and an inquiry-based learning approach.

Our internationally focused middle and high school offers students a unique preparatory, multilingual education providing them with the necessary skills for university and life beyond. Students are taught in a multilingual environment, graduating with literacy skills in at least two languages. For younger students we offer a German-immersion focused preschool and elementary program, educating engaged, independent, and balanced learners.

At Alto, we believe that the world needs young people eager to take on today’s and tomorrow’s challenges. Alto International School equips students with the skills and confidence to contribute to making our world a better place.
