Problem-solving using mathematics in various aspects of daily life encourages the importance of mathematical modeling skills. Mathematical modeling holds a crucial role, particularly when solving real-world or contextual problems, as it bridges the extra-mathematical world and the mathematical world. This paper discusses a study on the mathematical modeling skills of eighth-graders in solving contextual problems. This study aimed to investigate the mathematical modeling competency level achievement of the students. This study used the qualitative research method with a case study approach, consisting of five major stages: design, preparation, data collection, data analysis, and reporting. In the design stage, we determined the research focus, and in the preparation stage, we developed research instruments. We collected data by giving tests to 24 participants. After we analyzed the data, we reviewed and rearranged all of the research stages. The results showed that, out of six levels of mathematical modeling competency, which includes level 0 to level 5, most students only achieved level 3. Therefore, we conclude that the students are not yet capable of carrying out all aspects of the mathematical modeling processes. © 2023 Author(s).
