The Civil Rights Data Collection, 2006 (CRDC 2006), is part of the Civil Rights Data Collection (CRDC) program. CRDC 2006 (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. CRDC 2006 achieved an unprecedented 100% response rate for LEAs and a 99.6 % response rate for schools. Key statistics produced from CRDC 2006 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.
