This report presents selected findings from the Public School and Private School Data Files of the 2011-12 Schools and Staffing Survey (SASS). SASS is a nationally representative sample survey of public and private K-12 schools, principals, and teachers in the 50 states and the District of Columbia. School districts associated with public schools and library media centers in public schools are also part of SASS. Developed by the National Center for Education Statistics (NCES) of the Institute of Education Sciences within the U.S. Department of Education and conducted by the U.S. Census Bureau, SASS was first conducted in school year 1987-88. Since then, SASS has been conducted six times: in school years 1990-91, 1993-94, 1999-2000, 2003-04, 2007-08, and, most recently, 2011-12.
