This set of Web Tables is the fourth in a series of four that together provide key information about 2011-12 first-time postsecondary students' characteristics and their 6-year retention, persistence, attainment, withdrawal, stopout, and transfer rates. The series draws on data collected for the 2012/17 Beginning Postsecondary Students Longitudinal Study (BPS:12/17)--a nationally representative longitudinal sample survey conducted by the National Center for Education Statistics (NCES)--which followed first-time students for 6 years after they began their postsecondary education. This fourth set of Web Tables has two sections. Section 1 focuses on withdrawal, presenting the year-by-year, cumulative rates at which first-time students withdrew from postsecondary education without a degree. These withdrawal rates are shown in terms of the academic years (from July 1 to June 30) in which students were not enrolled and had not returned by spring 2017. Section 2 of these Web Tables explores stopout and transfer. "Stopout" is defined as a break in enrollment of 5 or more consecutive months.
