Mission Statement:

Our mission is to be an exemplary learning community—enriched by differences, informed through inquiry, global in reach.

Philosophy/Belief Statement:

Our challenging international program draws on classroom-based research on pedagogical practices and curriculum design from renowned organizations such as the International Baccalaureate Organization (IB) and Project Zero, a research group based in the Graduate School of Education at Harvard University.

The WIS educational approach reflects the globalized, interconnected society in which we live, giving students a world perspective in mathematics, the sciences, social sciences, languages, literature, technology and the arts.


  • From Preschool through Grade 5, students follow the inquiry-based IB Primary Years Program. Preshool to Kindergarten students are fully immersed in French or Spanish. From Grades 1-5, studies are dual language: English/French or English/Spanish.
  • In Middle School (Grades 6-8) and Grades 9-10 the academic program continues to develop deep thinking skills to enhance understanding. Teachers emphasize methods from Project Zero.
  • All students in Grades 11 and 12 are enrolled in the IB Diploma Program (DP), which prepares them to take exams to receive the International Baccalaureate Diploma in addition to a WIS diploma. The DP is a comprehensive, internationally-focused curriculum that places emphasis on deep understanding of complex topics.
