This survey was conducted by the National Center for Education Statistics (NCES) using the Fast Response Survey System (FRSS). FRSS is designed to administer short, focused, issue-oriented surveys that place minimal burden on respondents and have a quick turnaround from data collection to reporting. Questionnaires for the survey "Dual Credit and Exam-Based Courses" were mailed in fall 2003 to a representative sample of 1,499 regular public secondary schools in the 50 states and the District of Columbia. The sample was selected from the 2001-02 NCES Common Core of Data (CCD) Public School Universe file, which was the most current file available at the time of selection. The sampling frame includes 17,059 regular secondary schools. The estimated number of schools in the survey universe decreased to an estimated 16,483 because some of the schools were determined to be ineligible for the FRSS survey during data collection. Data have been weighted to yield national estimates. The unweighted and weighted response rates were both 92 percent. Detailed information about the survey methodology is provided in appendix A, and the questionnaire can be found in appendix B.
