The Civil Rights Data Collection, 2009-10 (CRDC 2009-10), is part of the Civil Rights Data Collection (CRDC) program. CRDC 2009-10 (https://ocrdata.ed.gov/) is a cross-sectional survey that collects data on key education and civil rights issues in the nation's public schools, which include student enrollment and educational programs and services, disaggregated by race/ethnicity, sex, limited English proficiency, and disability. LEAs submit administrative records about schools in the district. LEAs and BOCES-type regional education centers functioning as LEAs were sampled. Prior to 2011-12, charter schools were primarily sampled if they were part of a LEA, not if they were a separate charter school district. For CRDC 2009-10, 100% of LEAs and 100% of schools provided data. Key statistics produced from CRDC 2009-10 can provide information about critical civil rights issues as well as contextual information on the state of civil rights in the nation, including enrollment demographics, advanced placement, discipline, and special education services.
