Critical thinking skill is one of important skills in the 21st century. With critical thinking skills, people can observe a phenomenon from different perspectives. Therefore, it will lead individuals to think more critically in responding to information received. This study aimed to product self-perception instrument of students’ critical thinking skill that valid and reliable. This research used a modification from 6 steps of research by Borg and Gall. The credibility of instrument is observed from its validity, reliability, exploratory factor analysis, and validation result by the experts. To examine validity and reliability of this instrument, researchers adopted SPSS 23. Results showed that there were 13 items in self-perception instrument of critical thinking skills with a valid and reliable category. Exploratory factor analysis test results show that the 13 items that have been developed form 3 critical thinking skills factors, namely analysis, evaluation, and synthesis. In addition, results showed that the self-perception instrument of critical thinking skills which has been implicated is in the category of “very good” and it is highly valid to measure the levels of self-perception of critical thinking skills. For example in natural science learning activities.
