Most DIU courses are offered in either the Fall or Spring terms (with a few courses offered in both). But the other three terms offer a very limited number of courses.
May-Extended term is mainly for Intensive courses offered by CEWA (World Arts department) and CIS (the undergraduate College of International Studies).
Year-term is currently only for students taking the CTD (Certificate in Tropical Agriculture Development) courses taught in person at the ECHO research farm campus in Florida.
Summer term varies in the courses it offers, and overlaps with the longer May-Extended term.
DIU does not publish a single comprehensive full-academic-year PDF schedule of courses for all of our terms. But see the “Academic Calendar” section of the catalog, and the “Typical Course Offerings By Term” section that immediately follows it. Also see the Course Listing section of the catalog to see when any particular course is likely to be offered.
Be aware that DIU is not always able to offer a course in the term that the catalog says it is typically offered, so always consult the course schedule for a specific term to see if it is offered.
