From the Common Core of Data website:

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 database of all public elementary and secondary schools and school districts.

Information on the Common Core of Data (CCD)

The primary purpose of the CCD is to provide basic information on public elementary and secondary schools, local education agencies (LEAs), and state education agencies (SEAs) for each state, the District of Columbia, and the outlying territories with a U.S. relationship. CCD is composed of two components: Nonfiscal CCD and Fiscal CCD.

From the National Center for Education Statistics:

"With increasing concern about alternatives in education, the interest and need for data on private education has also increased. NCES has made the collection of data on private elementary and secondary schools a priority.The purposes of this data collection activity are; a) to generate biennial data on the total number of private schools, teachers, and students; and b) to build an accurate and complete list of private schools to serve as a sampling frame for NCES surveys of private schools. The PSS began with the 1989-90 school year and has been conducted every two years since."

The School Survey on Crime and Safety (SSOCS) is managed by the National Center for Education Statistics (NCES) on behalf of the United States Department of Education (ED). SSOCS collects extensive crime and safety data from principals and school administrators of public schools in America. Data from this collection can be used to correlate school characteristics with violent and serious violent crimes in American schools. Furthermore, data from SSOCS can be used to assess what school programs, practices, and policies are used by schools in their efforts to prevent crime. SSOCS has been conducted three times, in school years 1999-2000, 2003-2004, and 2005-2006. The 1999-2000 School Survey on Crime and Safety (SSOCS:2000) was developed by the National Center for Education Statistics (NCES) and conducted by Abt Associates Inc. Funding for the survey was provided by the Office of Safe and Drug Free Schools. Questionnaire packets were mailed to 3,366 public primary, middle, high, and combined schools. A total of 2,270 public schools submitted usable questionnaires for a weighted response rate of 70 percent. Data were collected from March 27, 2000 to August 15, 2000.

The School Survey on Crime and Safety (SSOCS) is managed by the National Center for Education Statistics (NCES) on behalf of the United States Department of Education (ED). SSOCS collects extensive crime and safety data from principals and school administrators of public schools in America. Data from this collection can be used to correlate school characteristics with violent and serious violent crimes in American schools.

TIMSS Advanced was conducted in 1995, 2008, and 2015." 

"PIRLS has monitored trends in reading achievement at the fourth grade every five years since 2001. PIRLS 2026, the sixth assessment cycle of PIRLS, will provide policymakers and researchers with data on 25 years of trends in student achievement in reading literacy.PIRLS 2026 completes the transition to a fully digital assessment, concluding a process that began with PIRLS 2021. ePIRLS, an innovative assessment of online informational reading, was introduced in 2016 as an optional component and is now integrated into the digital assessment."

Established in 1975, the Fast Response Survey System (FRSS) collects issue-oriented data useful to educational analysts, planners, and decision makers.

This file was designed to enable users to locate instructional programs by crosswalking from the previously used Handbook VI code listings to the new Classification of Instructional Programs (CIP) code listings. The CIP is a taxonomic coding scheme of educational instructional programs that was originally developed by the U.S. Department of Education's National Center for Education Statistics (NCES). The CIP was intended to establish standard terminology to improve the communication and exchange of information with regard to instructional programs and to standardize record-keeping. Among the intended users of the CIP system, in addition to the federal government, are state governments, local governments, educational institutions, education research organizations, accrediting agencies, professional associations, and individual researchers.

This study analyzes GPA data from the transcripts of college grades using the Baccalaureate and Beyond survey data from the National Center for Education Statistics at the US Department of Education. It reports GPAs overall and for 12 undergraduate majors including economics. The regression analysis investigates the likely effects of prior ability or achievement, demographics, and institutional variables on both the overall GPA and GPAs in selected academic subjects, including economics. Gender differences are explored for the marginal effects of taking a course in a subject and differences in the percentages of "A" grades earned when a course is taken.

The Comparable Wage Index for Teachers (CWIFT) is an experimental index created by the Education Demographic and Geographic Estimates (EDGE) program at the National Center for Education Statistics (NCES) to facilitate comparison of educational expenditures. The CWIFT is a measure of the systematic, regional variations in the wages and salaries of college graduates who are not PK-12 educators as determined by reported occupational category. It can be used by researchers to adjust school district-level finance data in order to make comparisons across geographic areas. The CWIFT is based on data from the American Community Survey (ACS), a continuous household survey conducted by the U.S. Census Bureau. The ACS provides information about the earnings, age, occupation, industry, and other demographic characteristics for millions of U.S. workers. The CWIFT measures wage and salary differences for college graduates, using an analysis that is modeled after the baseline analysis used to construct the original CWI released by NCES in 2006.

The School District Data Book (SDDB) is an education database and information system. It contains an extensive set of data on children, their households, and the nation's school systems. Under the sponsorship of the National Center for Education Statistics, the Bureau of the Census has produced special tabulation files using the basic record files of the 1990 Census of Population and Housing by school district. These tabulation files contain aggregated data describing attributes of children and households in school districts. Data are organized by seven types of tabulation records: (1) characteristics of all households, (2) characteristics of all persons, (3) characteristics of households with children, (4) characteristics of parents living with children, (5) children's household characteristics, (6) children's parents' characteristics, and (7) children's own characteristics.
