This report provides descriptive national data on the prevalence and characteristics of dual enrollment programs at postsecondary institutions in the United States. For this survey, dual enrollment refers to high school students earning college credits for courses taken through a postsecondary institution. The National Center for Education Statistics (NCES) previously collected data on dual enrollment and dual credit for the 2002-03 academic year from postsecondary institutions and high schools (Kleiner and Lewis 2005; Waits, Setzer, and Lewis 2005). To gather current data on dual enrollment and dual credit, NCES fielded an updated survey of postsecondary institutions on dual enrollment and a complementary survey of high schools on dual credit. The study presented in this report collected information for the 2010-11 academic year from postsecondary institutions on the enrollment of high school students in college-level courses within and outside of dual enrollment programs, and dual enrollment program characteristics. NCES, part of the Institute of Education Sciences, conducted this survey in fall 2011 using the Postsecondary Education Quick Information System (PEQIS). PEQIS is a survey system designed to collect small amounts of issue-oriented data from a nationally representative sample of institutions with minimal burden on respondents and within a relatively short period of time. Because the purpose of this report is to introduce new NCES data from this survey through the presentation of tables containing descriptive information, only selected findings are presented. These findings have been chosen to demonstrate the range of information available from the PEQIS dual enrollment study rather than to discuss all of the data collected; they are not meant to emphasize any particular issue. The findings are based on self-reported data from postsecondary institutions. Appended are: (1) Standard Error Tables; (2) Technical Notes; and (3) Questionnaire. (Contains 31 tables and 13 footnotes.)
