A key component of a DCIS education is the requirement that students develop a portfolio of their best work each year that reflects the four domains of global leadership (Investigate the World, Recognize Perspectives, Take Action, Communicate Ideas). For each work in their portfolio, students include an artifact of the piece, which could be the work itself or some representative documentation of it, such as scanned images, photographs, an image with a link to a YouTube video for a performance-based project, etc. They also include a written reflection with the artifact that describes why they are proud of the piece.
Students work with their Advisement teacher to keep the portfolio up to date through the end of eighth grade. If students stay through high school, they maintain a portfolio through the end of their senior year, when they formally present their portfolio to a panel for review. The presentation typically results in a recommendation that the student receive the Diploma of International Studies, which becomes part of the portfolio.
