CISP is an interdistrict grant program that partners urban and suburban schools. While the students learn more about other regions of the world, they also learn about one another. The schools interact with one another all year after school, building lasting relationships with one another. Past topics have included Migration, International Celebrations, Sports and Games, Martial Arts, Art and Architecture, and Global Economies. PIER works with CISP to design and implement activities appropriate for high school students interested in international studies.
