National Assessment of Educational Progress (NAEP)
National Assessment of Educational Progress (NAEP)
The Common Core of Data (CCD)
The Common Core of Data (CCD) is the U.S. Department of Education’s primary database on public elementary and secondary education in the United States. CCD is a comprehensive, annual, national statistical database of all public elementary and secondary schools and school districts, which contains data that are designed to be comparable across all states.
The objectives of the CCD are twofold:
- Provide an official listing of public elementary and secondary schools and school districts
- Provide basic information and descriptive statistics on public elementary and secondary schools and schooling in general
The CCD survey annually collects data about all public elementary and secondary schools, all local education agencies (LEAs), and all state education agencies (SEAs) throughout the United States. CCD contains three categories of information:
- General descriptive information on schools and school districts – name, address, telephone number, and type of locale
- Data on students and staff – selected demographic characteristics
- Fiscal data – revenues and current expenditures
CCD is made up of a set of five surveys sent to state education departments. Most of the data are obtained from administrative records maintained by the SEAs. Statistical information is collected annually from public elementary and secondary schools (approximately 90,000), public school districts (approximately 16,000), and the 50 states, the District of Columbia, the Department of Defense Education Activity schools, and the outlying areas of American Samoa, Guam, and the Virgin Islands. The SEAs compile CCD requested data into prescribed formats and transmit the information to NCES.
Florida’s data is compiled by the Office of Education Information and Accountability Services in the Division of Accountability, Research, and Measurement (ARM). This office can be accessed through the Florida Department of Education’s website.
