National Center for Education Statistics, Elementary/Secondary Information System. Public School Data: The Department of Education's primary database on public elementary and secondary education in the United States is the Common Core of Data (CCD). The CCD surveys are conducted annually and collect data about all public elementary and secondary schools, all local education agencies, and all state education agencies throughout the United States. CCD contains three categories of information: general descriptive information on schools and school districts; data on students and staff; and fiscal data. The general descriptive information includes name, address, phone number, and type of locale; the data on students and staff include selected demographic characteristics; and the fiscal data cover revenues and current expenditures. Private School Data: The Private School Survey produces data similar to that of the NCES Common Core of Data (CCD) for the public schools. The target population for the survey consists of all private schools in the U.S. that meet the NCES definition (i.e., a private school is not supported primarily by public funds, provides classroom instruction for one or more of grades K-12 or comparable ungraded levels, and has one or more teachers. Organizations or institutions that provide support for home schooling without offering classroom instruction for students are not included).
