The Common Core of Data (CCD) is a universe collection of public elementary and secondary education data that is administered by the National Center for Education Statistics (NCES). The CCD is a system of five surveys, three nonfiscal and two fiscal. The nonfiscal surveys are the: (1) Public Elementary/Secondary School Universe Survey; (2) Local Education Agency Universe Survey; and (3) State Nonfiscal Survey of Public Elementary/Secondary Education. The fiscal surveys are the: (1) School District Finance Survey (F-33); and (2) National Public Education Financial Survey (NPEFS). The data for these surveys are provided by state education agencies (SEAs) through the CCD survey system. This report provides an overview of data from the CCD. Nonfiscal data are presented for school year 2004-05 (except high school completion data, which are for school year 2003-04), and fiscal data are presented for school year 2003-04 (fiscal year 2004). For all surveys, the U.S. totals presented in the tables and in the text include only the 50 states and the District of Columbia. Appended are: (1) Technical Notes; and (2) Glossary. (Contains 10 tables and 10 footnotes.)
