The Survey of Pre-service Teachers' Knowledge of Teaching and Technology instrument is one popular tool designed to measure Technological pedagogical content knowledge (TPACK). This study extends the measurement framework by providing a confirmatory factor analysis of the theoretical model proposed by Schmidt et al. (2009) on a sample of 227 preservice teachers from four public institutions of higher education in the southeastern United States.

The data did not fit the theoretical 10-factor model implied by Schmidt et al. (2009), thus, an exploratory factor analysis was conducted to determine the optimal structure of the measurement tool for these data. This resulted in a nine-factor model, and there were measurement issues for several of the constructs. Additionally, the article provides evidence of external validity by correlating the instrument scores with other known technology constructs.
