The audience for the instrument is K-12 science teachers. It solicits information regarding their opinions, their preparation, and their teacher practice. The questionnaire was developed and administered to a nationally representative sample of science teachers as part of the 2012 National Survey of Science and Mathematics Education. All of the participating teachers answered a core set of items (about 25-30 minutes of survey time). In addition, teachers were randomly assigned to one of two sets of additional items, Matrix A or Matrix B (about 10-15 minutes of survey time). Teacher questionnaires were also customized for “self-contained” and “not self-contained” teachers. Web-based administration allowed customization of surveys “on the fly,” such that respondents were not presented with irrelevant items.
