While NSC has been around for quite some time, it is relatively new to academic researchers and policy-makers. This paper explores the strengths and weaknesses of the NSC data for a variety of research and policy purposes. We exploit a unique dataset that includes measures of postsecondary attainment from two sources: the NSC and transcripts obtained from Michigan?s public colleges. We use these data to examine how measurement error in the NSC data affects estimates of the level, trends, and socioeconomic gaps in postsecondary attainment. We also calculate sector-, group- and state-specific NSC coverage rates by comparing enrollment at the universe of colleges (contained in IPEDS) to enrollment at the subset of colleges that report to NSC.
