This study was carried out to develop a valid and reliable measurement tool that can measure the awareness of mathematics teachers about the nature of the transition from arithmetic to algebra. The survey model, one of the quantitative research methods, was used in the study. Three hundred forty-five mathematics teachers participated in the study. Exploratory factor analysis was applied to the data obtained from 254 of these teachers, and confirmatory factor analysis was applied to the data collected from 91 of them. The results revealed that the "Awareness Scale for the Nature of Transition is valid and reliable.
