Abstract
<jats:p>The article theoretically substantiates the concept of partner mentorship as a key factor in developing the acme-potential of a young teacher against the backdrop of modern educational challenges and systemic reforms. The study comprehensively reveals the nature, core principles, and structural components of partner mentorship based on equality, mutual trust, and reciprocal professional growth. Special attention is paid to the analysis of collaborative models, including co-mentoring, peer mentoring, and network mentoring. The author characterizes the specific features of each model and evaluates their functional potential in facilitating the smooth professional adaptation of novice educators into the school environment. The paper demonstrates that the integration of these mentorship models effectively fosters the development of professional subjectivity, deep reflexivity, and emotional resilience among young teachers. The mechanisms of psychological and pedagogical support detailed in the research help novice educators overcome professional crises, reduce reality shock, and prevent early burnout. It is established that partner mentorship shifts the traditional hierarchical "master-student" paradigm toward a horizontal interaction, which stimulates the continuous self-actualization and self-improvement of both participants. The findings emphasize that network and peer mentoring resources are vital for building sustainable professional communities and enhancing digital pedagogical competencies in times of crisis. The practical significance of the study lies in providing conceptual foundations and methodical recommendations that can be utilized by school administrations, postgraduate pedagogical education systems, and cherries of higher education to optimize induction programs for early-career teachers.</jats:p>
