The International Award (IA)

Students are engaged in hiking and camping and the final evaluation includes a student led overnight expedition. Our most recent group of students completed their requirements to the IA.

Real-life experiences

CAIS is developing a series of Expeditions. Thanks to the advice and help of the experienced Scuba Diving trip leaders at Yokohama International School, CAIS teacher Paul Bergot planned and organized the first CAIS scuba diving expedition which took place in early November 2019.
