Abstract: Critical thinking is one of the higher-level thinking skills that has been naturally applied in schools and is a way of learning that can be done by teachers. According to Ennis (1985), critical thinking skills are: 1) Providing simple explanations, 2) Building basic skills, 3) Making further explanations, 4) Formulating alternative solutions, 5) Summarizing. With the ability to think critically on the topic of environmental change, it is hoped that students can better understand the environmental conditions around the students themselves and be able to solve every problem faced by the students themselves. The purpose of this study is to describe the profile of critical thinking skills in environmental change materials owned by grade XI students at Brebes High School with a population of 36 students. The sample of this study was carried out using a saturated sample or carried out randomly. The data collection technique was carried out using a test in the form of a critical thinking essay on environmental change material. Non-test data collection in this study was conducted using interviews. The results of the study were then analyzed and classified at the level of critical thinking ability into five categories, namely very low, low, medium, high and very high. This classification is used to interpret the level of mastery of critical thinking skills that students have. The results show the highest indicator value of 46.7% or in the medium category, while the result with the lowest sub-indicator is 38.5%. The conclusion obtained in this study is that students' critical thinking skills are classified at a low level, as evidenced by the average result of the percentage of critical thinking scores that are only 41.48% or are considered low. This result is supported based on the results of interviews with the teaching teacher who said that the students who were the subjects of the research were fairly good at some students in solving problems
