This study examines the relationship between teaching quality, teacher self-efficacy, and students' mathematics achievement among junior high school students in Ghana, utilizing Realistic Mathematics Education and Self-Determination Theory as frameworks. A stratified purposive sample of 507 junior high school mathematics teachers from eight regions was selected, employing a correlational cross-sectional survey design. Structural Equation Modeling (SEM) tested the hypotheses that teaching quality positively affects mathematics achievement, teacher self-efficacy influences teaching quality, and self-efficacy mediates the relationship between teaching quality and achievement. Results confirmed that high-quality teaching significantly improves mathematics achievement, especially when contextualized with RME principles. Teacher self-efficacy emerged as a critical factor in enhancing teaching quality and directly influencing student outcomes. Mediation analysis showed that teacher self-efficacy strengthens the effect of teaching quality on achievement. These findings highlight the need for educational policies to focus on professional development that boosts teachers' efficacy and promotes realistic, student-centered instructional strategies.
