The aim of this study was to assess the domain-general CT skills of 8th grade students in Turkey. In the study, first, the domain-general CT scale was adapted to Turkish, and then relations of the CT skills with gender, computer possession, internet access, and programming experience were examined. This survey research was conducted with the 284 eighth grade students. The data were analyzed through confirmatory factor analysis, independent sample t-test and Pearson correlation test. The results of the confirmatory factor analysis and Cronbach alpha showed that the Turkish version of the domain-general CT scale was valid and reliable. T-test results showed no significant difference in the CT skills of the students according to gender, computer possession and internet access. A statistically significant difference in algorithm, evaluation, generalization, and general CT skills was found between students who learned programming and those who did not. Correlational tests revealed that there was a positive and significant relationship between the programming experience of students who learn programming and their CT skills. As students' programming experience increased, their CT skills also increased. The results of the research were discussed, and recommendations for policy-makers and implementers were included.
