This supplemental feature to the National Student Clearinghouse Research Center's "Signature Report on College Completions" released in December 2016 (ED580301), contains an analysis of the eight-year completion outcomes for the fall 2010 cohort. In the Center's previous signature reports on college completions, a brief analysis of the eight-year outcomes following the main discussion of six-year outcomes is provided. In response to the growing need for educational researchers to extend the time period given for graduation rate analyses, the Signature Report series on College Completions will now include an expanded examination of the eight-year completion outcomes as a supplemental feature. Among the key findings are: (1) The national total completion rate for the fall 2010 cohort increased 5.6 percentage points, from 54.8 percent at the end of six years to 60.4 percent at the end of eight years; (2) Four-year public and two-year public institution starters had fairly similar completion gains; (3) Two-year public starters had the highest proportion of completions at a different institution (36.8 percent of all completions) by the end of eight years in comparison to four-year public (24.1 percent) and four-year private nonprofit starters (20.3 percent); and (4) The completion rate increased approximately 6 percentage points for both men and women. Overall, women complete a credential at higher rates than men, where the six-year completion rate for women (58.2 percent) is higher than the eight-year completion rate for men (57.4 percent).
