The purpose of this study is to use item response theory (IRT) as well as exploratory and confirmatory factor analyses (EFA and CFA) to investigate the survey from Ross et. al.'s (2003) “A Survey Measuring Elementary Teachers’ Implementation of Standards-Based Mathematics Teaching.” IRT clarifies how the items and response categories function, whereas EFA and CFA reveal the factor structure measured.
