Memorandum for the NCES Review Tracking System (RTS) - IPEDS Data Collection Cycle

2018-19 IPEDS Data Collection: Winter Data Release – Provisional Level

The provisional level data release of the components collected during the winter collection period of the 2018-19 Integrated Postsecondary Education Data System (IPEDS) does not contain substantive changes in file structure or file documentation compared to the previous year. The data are released to the public through the "Use the Data" portal ( on the IPEDS website. The IPEDS Methodology has been reviewed and approved by the NCES Review Staff and is currently posted on the IPEDS website as a resource for data users. 

IPEDS is an annual, large-scale, web-based survey that collects institution-level data from postsecondary institutions in the United States (50 states and the District of Columbia) and other U.S. jurisdictions.1 For more information about the IPEDS Survey, its 12 components, and data release procedures visit This memorandum documents the IPEDS universe of reporting institutions and response to the winter collection period of the 2018-19 IPEDS, which was open from December 12, 2018 to February 13, 2019 .

2018-19 IPEDS Universe of Institutions

The IPEDS universe is established during the fall collection period. During the 2018-19 collection year, there were 6,353 Title IV institutions and administrative offices 2 in the United States and other jurisdictions of the United States, such as Puerto Rico. For 2018-19, a total of 479 postsecondary institutions were reported exclusively by a parent institution and are not included in the universe counts. The four U.S. service academies that are not Title IV eligible are included in the IPEDS universe because they are federally funded and open to the public3.

NCES statistical standards require that the potential for nonresponse bias for all institutions be analyzed for sectors for which the response rate is less than 85 percent. Because response rates were nearly 100 percent for each survey component, no such analysis was necessary.

Table 1 provides an overview of the number of institutions responding to the components that comprise the fall and winter collection periods. This table is updated after each collection period’s data release. Appendix A provides a summary of responses for the previous collection year for comparison purposes. Appendix B shows a table of institutions with Title IV status changes4. Of the 478 institutions that changed Title IV status in 2018-19, 385 were for-profit institutions.
