Teaching and Learning International Survey, 2013

The universe of interest was composed of schools where ISCED Level 2 education (grades 7, 8, and 9) is provided along with the affiliated principals and teachers. The TALIS 2013 U.S. sample was based on a stratified two-stage probability sample design. At the first stage the primary sampling units were individual ISCED Level 2 schools , selected systematically with probability proportional to size from the stratified sampling frame. At the second stage, the secondary sampling units were the in-scope teachers, selected randomly within the sample schools. TALIS minimum standards include a minimum of 200 schools, 3,400 teachers, and 20 teachers per school. In 2013, 140 U.S. schools participated; 111 principals and 2,034 teachers completed questionnaires. Data collection occurred from March 4 through May 31, 2013. The U.S. school sampling frame was developed from two national databases in the National Center for Education Statistics—public schools in the Common Core of Data (CCD, http://nces.ed.gov/ccd/) and private schools in the Private School Universe Survey (PSS,http://nces.ed.gov/surveys/pss/). These sources provide full coverage of all TALIS-eligible teachers in the education system in the United States. The TALIS school frame was constructed using the 2010-11 CCD and the 2009-10 PSS, the most current data at the time of the TALIS frame construction.
