This set of Web Tables is the second 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 second set of tables focuses on 6-year retention and attainment rates at the first institution students attended. The tables indicate the percentage of 2011-12 first-time postsecondary students who attained a certificate, an associate's degree, or a bachelor's degree by spring 2017 at the institution where they first enrolled. If they had not attained a credential at the first institution, these tables specify whether they were still enrolled at the first institution, had enrolled at a different institution, or had not enrolled at any institution after leaving the first institution. This publication first presents these retention and attainment rates at the first institution for all first-time postsecondary students (tables 1.1-A through 1.1-D). The following tables show rates for first-time postsecondary students attending institutions that vary by control (i.e., public, private nonprofit, and private for-profit) and level (i.e., less-than-2-year, 2-year, or 4-year). Tables 1.2-A through 1.2-D report rates for first-time postsecondary students who began at public 2-year colleges. Tables 1.3-A through 1.3-D and 1.4-A through 1.4-D present estimates for those who began at public and private nonprofit 4-year institutions. Subsequent tables focus on first-time postsecondary students' retention and attainment rates at different levels of private for-profit institutions, specifically, less-than-2-year institutions (tables 1.5-A through 1.5-D); 2-year institutions (tables 1.6-A through 1.6-D); and 4-year institutions (tables 1.7-A through 1.7-D). The final two sets of tables focus on 2011-12 first-time postsecondary students who began a bachelor's degree program at public (tables 1.8-A through 1.8-D) and at private nonprofit 4-year (tables 1.9-A through 1.9-D) institutions and present the percentages who completed a bachelor's degree at the first institution in 4 years or less, 5 years, or 6 years.
