The first round of data from the Integrated Postsecondary Education Data System's (IPEDS) newest survey component, Outcome Measures (OM), was released to the public in Fall 2017. Importantly, the IPEDS OM survey begins to address some of the limitations of the prevailing Graduation Rate (GR) component data. These rates have only included "traditional" college outcomes of first-time students, leaving out part-time students and many types of non-first-time students. Now that the wider diversity of students is represented, Western Interstate Commission for Higher Education (WICHE) observes important and even surprising trends about student outcomes. In this brief, WICHE explains the differences between the long-standing GR data and these new OM data. It also illustrates the additional progression and completion information the OM data provide about public postsecondary institutions in the WICHE region (representing 16 states and territories in the Western United States) and their undergraduate populations. The final section of the brief details additional changes to be incorporated in the next wave of OM data, and the Technical Glossary provides cohort and element definitions.
