This paper presents preliminary results from the National Study of Non-Credit Course Activity, which is funded by a grant from the Lumina Foundation. This research examines how non-credit data are collected and used by institutions, state and federal agencies, and national associations. An online survey was administered to all state SHEEO offices and to a sample of 2,086 Title IV, degree-granting institutions. Interviews were conducted with key informants, including association and agency staff. The results are used to describe a national portrait of non-credit activity, to develop a standard definition, and to highlight emerging policy issues related to the use of non-credit data.
