In addition to the concepts and attitudes as outlined above, the knowledge from the curriculum, and the Transdisciplinary Skills, action is another essential element of the philosophy of an international education.  ISB provides students the opportunity and empowers them to choose their actions, to act, and to reflect on these actions in order to make a difference in and to their world.

The action component of the PYP involves service in the widest sense of the word: service to fellow students, to the staff, and to the community.  Through such service, students are able to grow both socially and personally, developing skills such as cooperation, problem solving, conflict resolution, and creative and critical thinking.  These actions are, moreover, ways in which the students exhibit their commitment to the attitudes that teachers seek to engender within the PYP classroom.
