This school-level database contains data from the following sources: the National Center for Education Statistics’ Common Core of Data (CCD), the Civil Rights Data Collection (CRDC), the US Department of Education’s EDFacts, and IPUMS' National Historical Geographic Information System (NHGIS). Although the CCD includes information on schools over a long period, the topics covered are more limited than in the CRDC. Data elements in the CCD include basic information about the school (e.g., location, grade offerings, and charter status) and student enrollment demographics. The CRDC contains three years of data on every public school on such topics as student discipline, retention, course enrollment, chronic absenteeism, and SAT or ACT test-taking. EdFacts provides assessment data broken down by various subgroups. NHGIS provides census geographies such as tract and block group for each school.
