The Guidance Services and Research and Development Departments of the College Board coordinated an investigation of the results of a national high school survey. This survey, administered in 2000, follows a similar, large-scale survey of high schools in 1993 by the College Board. The current research report is designed to provide the reader with detailed and updated information about high schools in the United States. It provides basic facts, figures, and trends about common features among the participating institutions. The report also presents evidence in support of observable trends among the educational and demographic factors of concern as of 2000 and 1993. Two appendices are included: (1) 2000 Advanced Placement Examination® (AP®) Participation by Total School Enrollment and by Institution Type; and (2) Methodology and Survey Instrument.
