The National Student Clearinghouse (NSC) is a useful data source on U.S. postsecondary enrollment of students who have applied and/or enrolled at Harvard. Harvard staff now have the ability to request NSC data for internal projects by contacting OIRA. The University Data Advisory Group (UDAG) recently provided a detailed description of the request process in its April 2025 recommendation, which can be viewed on our Data Governance Portal (HarvardKey login required).
