Interdisciplinary studies are skills-centered programs of study that require that you draw from and integrate two or more disciplines to explain a phenomenon, solve a problem, or create a product. The result is one that could not have been achieved through just one discipline.
How should the USA prepare for a possible outbreak of Ebola? How valid a critique of religious belief is Voltaire’s poetic reflection upon the Lisbon earthquake? What does the development of mathematical principles reveal about the societies and cultures that produced them?
In order to respond to these questions properly, you need to integrate disciplines, combining the insights, skills, and approaches of different subjects in order to make progress. The interdisciplinary studies department is founded on the principle that a complete high school education should require students to engage with this kind of demanding and high level study, both because of its intrinsic educational value, and because of the growing need in the world at large for graduates who have skill and confidence with such study.
