Purpose: The current body of research has separately examined ethics education design and evaluation, as well as the development of ethical identity in managers. However, a notable deficiency in the literature lies in the absence of a comprehensive investigation into the interconnections between these two areas. This conceptual paper aims to address this lacuna. Design/methodology/approach: Building on the theoretical foundations of identity control theory, this paper presents a conceptual model that outlines the dynamics of ethics education for managers, whether outside the organization or as a human resource development (HRD) initiative. Drawing upon a diverse range of literature sources, the model places significant emphasis on the interactive nature of identity formation, taking into account both individual agency and the educational context. Findings: The conceptual model developed based on identity control theory illuminates the functioning of ethics education and its impact. The model illustrates the multifaceted nature of the relationship between ethics education and the development and sustenance of ethical identity in managers. It underscores the iterative process of identity control, wherein managers continuously navigate their ethical identities in response to internal and external influences. Originality/value: While ethics education in management and HRD studies is widely acknowledged, there is a significant gap in understanding the psychological mechanisms that explain the maintenance of self-identity and the dynamic interplay between individuals and their social environment. This gap is particularly relevant to educational programs, which not only shape the social environment for trainees but also aim to foster the development and preservation of their individual identities.
