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. The purpose of SASS is to collect information that can provide a detailed picture of U.S. elementary and secondary schools and their staff. This information is collected through the following surveys: district, school, principal, teacher, and library media center. The data were collected via mailed questionnaires with telephone and in-person field follow-up. The purpose of this First Look is to introduce new data through the presentation of tables containing descriptive information. Selected findings chosen for this report demonstrate the range of information available on the 2011-12 SASS Public School and Private School Data Files. The selected findings do not represent a complete review of all observed differences in the data and are not meant to emphasize any particular issue. This First Look report highlights findings from the SASS public and private school surveys. The tables in this report contain counts and percentages demonstrating bivariate relationships.
