Students are required to have the ability to implement mathematics in solving everyday life problems. A good solving process will produce an excellent solving ability. The existing problem-solving stages cannot be used in solving problems with the Higher Order Thinking Skills (HOTS) category. The aims of this research are 1). to know students' problem-solving process in solving HOTS category questions; 2). To design the stages of problem-solving that can be used to solve HOTS category questions. Twenty-four students who took the differential calculus course in mathematics education at one of Indonesia's private universities made up the study group. The solving process is divided into high, medium, and low. The descriptive and qualitative research method describes the Polya stages' problem-solving approach. Researchers used four sets of problem-solving by making nine indicators. Based on the analysis results, it can be concluded that several indicators of the problem-solving stages have not been appropriately implemented, including I4, I8, and I9. In addition, the steps at the Polya problem-solving stage of devising a plan and looking back must be improved. Based on the findings above, research recommendations design the stages of problem-solving consisting of 6 steps. Future research will develop steps of problem-solving with the characteristics of the HOTS category questions. © 2024 City University of New York. All rights reserved.
