Purpose: The purpose of this paper is to propose a new theory promoting long-term learning among mid-level leaders in schools via simulation training. Design/methodology/approach: The proposed model is derived from the socioecological model, a model that takes into account the multifaceted effects of different disciplines. The proposed interdisciplinary model may be assimilated by considering the ethical-social context of mid-level leaders undergoing simulation training. Findings: A new interdisciplinary model emerges from the original socioecological model. The model's interdisciplinary approach, crossing disciplines such as leadership, management and learning, enables this model to serve as a platform for research that enhances long-term learning among mid-level leaders in schools. Practical implications: The elicited model, which can be assimilated via simulation training, may enhance long-term learning among mid-level leaders in schools and help to shape educational policy, improve learning and impact the exchange of knowledge between countries. Originality/value: The emergent interdisciplinary model is expected to foster thinking beyond the traditional boundaries of each discipline and to enhance long-term learning in an ethical context among mid-level school leaders. The model's interdisciplinary approach, which creates new emergent dimensions suited to the challenges of the 21st century, makes this model a unique platform for research and simulation training that enhances long-term learning.
