Teacher turnover is an important factor influencing staff stability and the effectiveness of educational organizations. The growing complexity of the educational environment increases the need for practical tools that allow educational administrators to identify factors contributing to staff instability and potential turnover risks. The aim of this study is to develop a diagnostic model for assessing the risk of teacher turnover in educational organizations. The theoretical and methodological framework of the study is based on research on teacher professional resilience, occupational stress, professional motivation, and human resource management in education. The study employs methods of literature analysis and synthesis, systematization of scientific findings, and conceptual modeling. The analysis made it possible to identify key groups of factors influencing teacher turnover risk, including organizational conditions of professional activity, professional motivation of teachers, psychological aspects of professional activity, and opportunities for professional development. Based on these factors, a diagnostic model was developed that includes a system of indicators and a scoring scale for assessing the level of turnover risk. The proposed model allows for a quantitative assessment of teacher turnover risk and helps identify problematic areas in the personnel policy of educational organizations. The practical significance of the study lies in the possibility of applying the developed diagnostic tool for monitoring staffing conditions and supporting evidence-based management decisions aimed at strengthening staff stability in educational institutions.
