Contextual problem-solving ability is a crucial skill that students, particularly those in vocational schools, must possess, as they will immediately enter the workforce. To optimize students' abilities, research was conducted on the variation of students’ difficulties in solving problems. This study aims to identify variations in vocational high school students' difficulties in solving contextual problems of the system of linear inequalities in two variables based on Polya’s theory and to offer alternative solutions that can be used to overcome these difficulties. The type of research used is qualitative with a descriptive approach. The study subjects were 3 students of 36 students of the grade XI vocational high school, who had received the material. These students were selected based on the category of abilities they had, namely high, medium, and low, as well as considerations of communication of teacher recommendation results. Data collection was carried out through tests and interviews. Based on the results of the study, it was found that 1) Low Ability Students (LAS) experienced many variation in difficulties at all stages in solving problems according to Polya’s theory, 2) Medium Ability Students (MAS) at the stage of understanding the problem experienced fewer variations in difficulties compared to the other three stages, 3) High Ability Students (HAS) at the stage of understanding the problem and making plans experienced fewer variation in difficulties compared to the other two stages. Apart from being based on Polya’s theory, students also experience other variations of difficulty, namely the difficulty in defining variables, constants, and coefficients correctly.
