 Baccalaureate and Beyond Longitudinal Study

The estimates and statistics reported in the tables and figures of this report are based on data from the Baccalaureate and Beyond Longitudinal Studies (B&B):B&B:93/94 and B&B:2000/01. The two B&B studies conducted by the U.S. Department of Education’s National Center for Education Statistics provide information on the education and work experiences of bachelor’s degree recipients. The B&B:93/94 and B&B:2000/01 studies were a 1-year follow-up of bachelor’s degree recipients who completed their degree between July 1, 1992 and June 30, 1993 and between July 1, 1999 and June 30, 2000, respectively, and who were first interviewed as part of the 1992–93 and 1999–2000 National Postsecondary Student Aid Studies (NPSAS), respectively. The 1992–93 graduates were followed up again in 1997 and 2003, but no data from these later follow-ups are used in this report. Data from all components of NPSAS (including the institutional record abstract, the student interview, matches with U.S. Department of Education financial aid records and SAT/ACT scores) are used as base-year data for the B&B studies.

The NPSAS studies included about 1,100 institutions and were based on a nationally representative sample of all students enrolled in postsecondary education institutions, including undergraduate, graduate, and first-professional students; each NPSAS study represents more than 16 million undergraduates who were enrolled at some time between July 1 and June 30 of the respective survey year. The survey frames for the NPSAS data collections used in this report were built from the Integrated Postsecondary Education Data Systems Institutional Characteristics file (IPEDS-IC) for 1990–91 and 1998–99. The estimates presented in this report are based on the results of interviews with approximately 10,000 bachelor’s degree recipients each year from sampling frames of about 12,500 in 1992–93 and 11,600 in 1999–2000. These bachelor’s degree recipients represent the approximately 1.2 million bachelor’s degree completers in each of the 2 years.1 Excluded from the final sample were students who were determined during the B&B interview or from transcripts not to have earned a bachelor’s degree during the relevant academic year (760 in 1992–93 and 70 in 1999–2000). The smaller number of exclusions in the later study reflects better methods to identify bachelor’s degree recipients.

The NPSAS sampling design was a two-stage design in which eligible institutions were selected at the first stage and eligible students were selected at the second stage within eligible, responding sample institutions. At both stages, sampling was stratified and implemented with probabilities proportional to the corresponding sizes in order to make the sample be representative of the relevant population in the United States and Puerto Rico. For sampling purposes, institutions were stratified according to type of control (public, private not-for-profit, and private for-profit) and level (less-than-2-year, 2-year, and 4-year).

The B&B interviews were done between June and October in 1994 and between July and November in 2001. Efforts were made both during and after data collection to ensure data quality (e.g., data cleaning, resolving possible discrepancies among different data sources—including situations in which a composite variable is derived from several item variables—and applying logical imputations for respondents missing data on one item while known for other items).
