Students are expected to acquire problem-solving skills as a goal of their mathematics education. Based on their self-efficacy, junior high school students' mathematical problem-solving abilities are the focus of this study. This study used a qualitative descriptive approach and was structured like a case study. A combination of interviews, a test of problem-solving abilities, and a self-efficacy questionnaire was used to gather data. Reducing, presenting, and drawing conclusions from data were all aspects of interactive analysis that were employed in data analysis techniques. Participants in this study ranged in self-efficacy from very high to very low; they were all eighth graders at SMP N 15 Padang. The findings revealed that: (1) students who scored higher on the self-efficacy scale also scored higher on all indicators of mathematical problem-solving ability; (2) students who scored lower on the scale had lower problem-solving abilities overall. © 2026 Author(s).
