This study aims to describe the effectiveness of the inquiry lesson model on chemical equilibrium material in improving higher-order thinking skills. The population in this study were all students of grade XI of SMA Negeri 14 Bandar Lampung in the 2025/2026 academic year consisting of 5 classes, namely XI 1 to XI 5. Sampling in this study used a purposive sampling technique and obtained class XI 1 as the experimental class and XI 2 as the control class. This study was a quasi-experimental study design with a nonequivalent pretest–posttest control group. The data of this study were analyzed by testing the difference in two means using the Independent Sample t-test. The results showed that the average n-gain of the experimental class was significantly higher than the average n-gain of the control class. The results of the Independent Sample t-test showed a significant difference in the average n-gain of students' higher-order thinking skills in the experimental class and the control class, so it can be concluded that the inquiry lesson model on chemical equilibrium material is effective in improving higher-order thinking skills.
