From GAIS to Alto

We are proud to announce our new name ‘Alto International School’ to reflect our growing multilingual program. Our new website is currently under construction. Visit AltoSchool.org to learn more.

Our internationally focused middle and high school program offers students a unique preparatory, multilingual education providing them with the necessary skills for university and life beyond. For younger students we offer a German immersion preschool and elementary program, educating engaged, independent, and balanced learners.

As an IB World School since 2007, Alto offers both the Primary Years Program (PYP) from Preschool through Grade 5, the Middle Years Program (MYP) from Grade 6 through Grade 10, and is a candidate school for the Diploma Program (DP) in Grades 11 and 12. Students are taught in a multilingual environment, graduating with literacy skills in at least two languages.

We are accepting applications for the 2017-18 school year for preschool, elementary school, middle school, and grades 9 & 10 in high school.
