In the 2003-04 academic year, approximately 4 million undergraduates began postsecondary education for the first time, enrolling in a wide variety of institutions, including 4-year colleges and universities, public 2-year community colleges, and for-profit institutions offering career-oriented and vocational programs. These Web Tables cover the enrollment experiences of a representative national sample of these 2003-04 first-time postsecondary students over a period of 6 academic years, from 2003-04 to 2008-09, and provide information about the rates at which these students completed degrees or certificates, transferred to other institutions, and left postsecondary education without attaining any degrees or certificates. The data are based on the 2003-04 Beginning Postsecondary Students Longitudinal Study, Second Follow-up (BPS:04/09). The tables are grouped into six sections. Section 1 presents the distribution of the first-time postsecondary students by demographic and enrollment characteristics within degree programs and within the types of institutions that they first attended. Section 2 presents 6-year attainment and persistence rates "at any institution." Section 3 presents the 6-year rates of attainment and retention "at the first institution attended." Section 4 presents 2003-04 first-time postsecondary students' 6-year persistence and attainment rates "at any institution" by the type of program (certificate, associate's degree, or bachelor's degree) in which they were enrolled during their first year (2003-04). Section 5 presents the year-by-year cumulative rates at which these students (1) withdrew from postsecondary education without a degree and (2) withdrew without a degree from the first institution attended. Section 6 presents information about the 2003-04 first-time postsecondary students who transferred, including both those who transferred without a degree as well as those who had attained a certificate or an associate's degree before transferring. Section 7 shows the bachelor's degree completion rates in 4 years or less, in 5 years, or in 6 years of 2003-04 first-time postsecondary students who started in bachelor's degree programs at public and at private nonprofit 4-year institutions. A glossary is included. (Contains 228 tables and 5 endnotes.)
