The research method used is a descriptive quantitative method. The sample used was 259 students. The instrument used for data collection is multiple choice test questions based on critical thinking skills indicators on plants' structure and function materials that have been validated from the expert evaluation team and statistics parameters including validity, reliability, discriminating power, and difficulty level. Questions were created based on 6 indicators of critical thinking skills, namely interpretation, analysis, evaluation, explanation, and self-regulation. The results showed that students' critical thinking skills in the interpretation indicator had a percentage of 58.3% with less categories, analysis indicators had a percentage of 35.1% with less categories, evaluation indicators had a percentage of 38.2% with less categories, inference indicators had a percentage of 39, 7% with less categories, explanatory indicators have a percentage of 38.2% with less categories, and self-regulation indicators have a percentage of 39.7% with less categories. Based on the results, it can be seen that the average critical thinking skills of students is 41.53% which shows students' critical thinking skills on plants' structure and function materials are still low.
