This study aims to develop a valid and reliable scale that can measure the intercultural awareness level of students in an educational environment with different cultures. For this purpose, the data obtained from a total of 535 students studying in grades 5-6-7 and 8 were included in the analysis by random sampling method. In this study, which was carried out in the general survey model, one of the quantitative research methods, 45 questions in the item pool prepared in three sub-dimensions as cognitive, affective, and psychomotor domains were presented to the expert opinion, and the evaluation results from the experts were analyzed with the Davis technique and 19 items were removed and it was decided to keep 26 items in the trial form. As a result of the exploratory factor analysis carried out to provide evidence for the construct validity of the measurement tool, 14 items in different dimensions and determined to be overlapping were removed from the analysis were carried out, and thus a structure consisting of three dimensions and a total of 12 items was reached. Confirmatory factor analysis was performed to examine the model-data fit of the obtained structure and it was determined that the model had a high fit. The two-half reliability coefficient of the measurement tool was determined as 0.74. Based on these findings, it was concluded that the Intercultural Awareness Scale is a valid and reliable measurement tool and teachers can use the developed measurement tool to measure the level of intercultural awareness in the classroom.
