In this study, it was aimed to develop a measurement tool that measures the level of intercultural sensitivity of adolescents in a valid and reliable way. For this purpose, a total of 1094 secondary school students, 675 for exploratory factor analysis, 445 for confirmatory factor analysis, and 73 for test-retest reliability, formed the study group. While creating the scale item pool, how the concept of culture is handled in primary and secondary school textbooks, measurement tools developed for this purpose, literature and student group interviews were used. The items that emerged in this way were reviewed by 4 field expert academicians and 3 field worker psychological counselors and necessary corrections were made. Before the 40-item form was applied to the students, a pilot application was made in a group of 10 students with different cultural characteristics, and the items were finalized according to the students' opinions. As a result of the exploratory factor analysis (EFA) and expert opinion on the data obtained as a result of the first application, 26 items were removed, and it was determined that the structure consisting of the remaining items explained 41.53% of the total variance. As a result of EFA, it was determined that the measurement tool consisting of 14 items consisted of two sub-dimensions: 'Openness to Culture' consisting of 9 items and 'Respect' consisting of 5 items. As a result of the confirmatory factor analysis (CFA) performed on the data obtained as a result of the second application on a different study group, the goodness of fit values of the scale were found to be χ2/sd = 2.17; RMSEA= .05; GFI = .95; CFI = .96; NFI = .95; IFI= .96; SRMR = .04 was found to be a perfect fit, and AGFI = .93 was found to be at a good fit level. In the Cronbach alpha calculation made to determine the reliability level of the scale in terms of internal consistency, a value of .78 for the 'Openness to Culture' sub-dimension, .75 for the 'Respect' sub-dimension, and .77 for the whole scale was obtained. In order to determine the reliability of the scale in terms of stability, a value of .90 for the 'Openness to Culture' sub-dimension, .87 for the 'Respect' sub-dimension, and .84 for the whole scale was obtained as a result of two applications performed 28 days apart in a different study group of 73 people. Taken as a whole, these data show that the Intercultural Sensitivity Scale for Adolescents (ISSA) is a valid and reliable tool in determining the level of intercultural sensitivity of secondary school adolescents.
