Computational thinking is recognized as a vital skill related to problem-solving in technological and non-technological fields. The existence of different sub-domains related to this skill has been pointed out. Therefore, there is a need for tools that measure these different sub-domains. Because of its structure that includes different skills, computational thinking has a structure different from that of the tools used to measure academic skills. Moreover, no special programming knowledge is required for tools that measure this ability. In order to measure this skill in younger age groups, it is possible to apply the measurement tool without adult support. At this point, it is aimed to reveal the computational thinking skills of Turkish children by adapting a test developed for the 7-9 age groups into Turkish. For this purpose, an adaptation research study was performed for TechCheck-2 developed by Relkin et al. (2020). In the study, a total of 372 primary school students studying in Ankara were contacted. Item and test analyses were performed on the data obtained as a result of the application of the test. The distinctiveness and difficulty values of the items making up the test and Kuder Richardson-20 scores were calculated. At the end of the analyses, it was seen that the test could be used as a valid and reliable measurement tool for Turkish children.
