Staff members from the Center for Survey Measurement (CSM) at the U.S. Census Bureau conducted 24 cognitive interviews with a shortened teacher questionnaire of the National Teacher and Principal Survey (NTPS) on behalf of the National Center for Education Statistics (NCES). The goal of the testing was to evaluate question wording, as well as compare answers to question pairs in which a question is asked both with and without instructions in a within respondent experiment. These results will be used to guide question selection for an upcoming field test.
