Improving the quality of teaching–learning processes has long been a major concern in school systems, and existing evidence has indicated that the absence of a comprehensive management framework can hinder sustainable enhancement of educational quality. Accordingly, the present study was conducted with the aim of designing a Total Quality Management (TQM) model tailored to the needs of schools. This research employed a qualitative design using thematic analysis. The study population consisted of all credible documents, scientific sources, and research studies related to TQM and teaching–learning processes, from which 48 sources were selected through purposive sampling. Data were analyzed using a three-stage coding process including initial, axial, and selective coding, and the analysis was carried out through constant comparison and iterative refinement of themes. The findings revealed that the proposed model comprised six core components—educational leadership, learner-centeredness, teacher empowerment, planning and continuous improvement, management of instructional processes, and quality evaluation—each containing several sub-themes that collectively contributed to the improvement of teaching–learning quality. These components demonstrated that alignment among leadership practices, professional development, instructional organization, and continuous evaluation played a key role in enhancing learning experiences and educational performance. Based on the results, the proposed modelare foundational pillars of TQM. Nevertheless, much of the existing literature has focused on administrative efficiency rather than the pedagogical core. Several scholars have suggested that the adaptation of TQM to instructional processes requires a deeper understanding of classroom interactions, student engagement, professional development, and curriculum alignment. Moreover, technological developments and modern learning theories have highlighted the need for TQM frameworks to integrate learner-centered principles and data-driven decision-making.
