The Common Core of Data (CCD) is an annual collection of public elementary and secondary education data by the National Center for Education Statistics (NCES) in the Institute of Education Sciences of the U.S. Department of Education. The data presented in this report are selected from the three nonfiscal components of the Common Core of Data (CCD) survey system: the Public Elementary/Secondary School Universe Survey; the Local Education Agency (LEA) Universe Survey; and the State Nonfiscal Survey of Public Elementary/Secondary Education. This First Look report presents findings on the numbers and types of public elementary and secondary schools and local education agencies and public school student enrollment and staff in the United States and other jurisdictions for school year (SY) 2011-12 from the provisional version 1a school universe file, provisional version 1a LEA universe file, and the provisional version 1a state universe file. The purpose of this First Look report is to introduce new data through the presentation of tables containing descriptive information; therefore, the selected findings chosen for this report demonstrate the range of information available when using data from the CCD non fiscal survey components. This First Look provides users with an opportunity to access provisional data that have been fully reviewed and edited. State education agencies (SEAs) report data annually for the nonfiscal CCD via the ED"Facts" collection system. SEAs submit separate files for each of the three nonfiscal survey components (school, LEA and state). For each survey, SEAs submit only aggregate sums of person-level data such as membership or number of teachers. The ED"Facts" collection opens for each school year beginning in January, with groups of data collected over a schedule throughout the year. The data in this report represent data reported from January 2012 through April 2013. The SY 2011-12 ED"Facts" collection will remain open to SEAs for revisions and corrections for approximately 3 years after the opening of the initial collection, continuing through the end of 2015. NCES may release additional revisions of the provisional data when necessary to reflect the most recent revisions reported from SEAs. Once the collection for SY 2011-12 closes, NCES will issue a Final version of the nonfiscal survey data files to include any final reported revisions. Appended are: (1) Methodology and Technical Notes; and (2) Common Core of Data Glossary. (Contains 4 tables and 2 footnotes.)
