One of the many pieces of "consumer information" that the Higher Education Opportunity Act (HEOA) requires the National Center for Education Statistics (NCES) to post on its College Navigator website is a student-to-faculty ratio for institutions in the IPEDS universe with undergraduate programs. NCES added the collection of this measure to the Integrated Postsecondary Education Data System (IPEDS) Fall Enrollment component for the 2008-09 data collection year and revised the methodology for the 2009-10 data collection year. This paper explores the challenges related to collecting a meaningful student-to-faculty ratio while minimizing reporting burden imposed on institutions, and makes suggestions for improvement in future IPEDS data collections. The report also includes an appendix that identifies the individuals who were interviewed for this paper.
