Overview

The Common Core of Data (CCD) is the 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: first, to provide an official listing of public elementary and secondary schools and school districts in the nation, which can be used to select samples for other NCES surveys. And second, to provide basic information and descriptive statistics on public elementary and secondary schools and schooling in general.

Design

The CCD survey annually collects 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.

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 state education agencies (SEAs). Statistical information is collected annually from approximately 100,000 public elementary and secondary schools and approximately 18,000 public school districts (including supervisory unions and regional education service agencies) in the 50 states, the District of Columbia, Department of Defense Schools, and the outlying areas. The SEAs compile CCD requested data into prescribed formats and transmit the information to NCES.

Policy and Research Issues
The five data sets within CCD can be used separately or in conjunction with one another to provide information on many topics of interest. Examples of CCD data that could be used to address important education issues are:

  1. size of school and pupil/teacher ratio;
  2. size of school district and region of the country;
  3. locale of school and racial/ethnic composition for selected states;
  4. racial/ethnic composition and pupil/teacher ratio for selected states;
  5. locale of school and percent of free-lunch eligible students for selected states;
  6. grade level and pupil/teacher ratio;
  7. size of school district and number of special education students;
  8. graduates; and
  9. state share of expenditure for education and expenditure per pupil.
