This National Center for Education Statistics (NCES) "First Look" report introduces new data for the universe of public elementary and secondary schools and agencies in the United States in school year (SY) 2014-15. Specifically, this report includes statistics that describe: (1) the numbers and types of public elementary and secondary schools and local education agencies (LEAs); (2) the operational status of schools and districts, including those that opened as new in SY 2014-15 or have closed since the prior school year; (3) student membership counts; teacher counts; (4) and; (5) pupil/teacher ratios. The public elementary and secondary universe data used in this report are from the nonfiscal components of the Common Core of Data (CCD). The CCD is the primary NCES database on public elementary and secondary education in the United States. The CCD includes a complete directory listing of all public schools and LEAs with the name, address, and descriptive characteristics for each school and LEA (e.g., operational status, type, charter status). The data also include aggregate counts of students in membership for each state, LEA, and school by grade and student demographic characteristics (e.g., race/ethnicity, sex) and aggregate counts of teachers and other staff in key occupational categories that are commonly found in schools. State education agencies (SEAs) report these data through the U.S. Department of Education's EDFacts Submission System (ESS), an electronic file submission system that facilitates transmission of data from the SEAs to the Department. This First Look is based on provisional data from the SY 2014-15 public elementary and secondary education universe that have been fully reviewed and edited. The purpose of a First Look report is to introduce new data through the presentation of tables containing descriptive information; therefore, the tables and selected findings chosen for this report are meant to illustrate some of the typical types of information available from the public elementary secondary universe files. The tables chosen include tabulations from only some of the available data items. The findings do not represent a complete review of all observed differences in the data and are not meant to emphasize any particular issue. The calculated totals in this report, identified as "United States" totals in tabulations and "national" estimates in text, include data for only the 50 states and the District of Columbia and exclude data for other jurisdictions. The following are appended: (1) Methodology and Technical Notes; and (2) Glossary.
