Teacher competence is a crucial factor in the sustainability of the educational process. However, the portrait of the low competence of teachers is still a severe problem in the process of implementing education. The development of teacher work spirituality is believed to be a significant factor in efforts to increase teacher competence more effectively. This study aims to reveal which aspects of the pedagogic, personality, social, and professional competencies of MI teachers in Tanggamus Regency require development and to what extent the work spirituality framework can be developed and applied to promote these competencies. The method used in this research is descriptive qualitative with a case study approach. Data were obtained from direct interviews, observation, and documentation of teachers, madrasah principals, and madrasah ibtidaiyah supervisors in Tanggamus district and were analyzed with data reduction, data display, and data verification. The results of the study explain that there are many aspects of the competence of Madrasah Ibtidaiyah teachers in Tanggamus, especially pedagogic competence and professional competence, that have not shown satisfactory results. Therefore, development efforts should be thoughtfully made by all relevant parties. In addition, the description of the research data also finds the potential for teacher work spirituality that can be optimized with the correct principles and implementation strategies to support the development of all madrasa teacher competencies and improve the quality of learning more effectively.
