ERG stands for Enrollment Requirement Group. ERGs are used in the course catalog and schedule of classes to restrict enrollment to specific student populations. They are the organizational method behind prerequisites (in the form of catalog requisites), reserve capacities (rCaps), and class level enrollment control (section level ERGs). ERGs can be built using a combination of student group codes, programs, plans, test scores, academic level, and courses.
The creation of and changes to ERGs applied to undergraduate College courses are directed by the Office of Undergraduate Curriculum, Policy, and Records (OUCPR) based on the College's Undergraduate Bulletin. ERGs are built and maintained by the Office of the Registrar. For questions about ERGs, please contact OUCPR at ugcurric@iu.edu.
