Abstract
<jats:p><p style="text-align: justify;"><strong>Context and relevance. </strong>Ensuring the professional longevity of teachers, maintaining their health and performance, requires a comprehensive study and the development of scientifically based technologies. This issue becomes particularly important in the context of an aging population and age-related changes in teachers themselves. <strong>Objective:</strong> to identify the relationships between indicators of teachers' professional longevity and professional burnout, as well as their life resources (psychological safety of the educational environment and resilience). <strong>Methods:</strong> the Professional Burnout Inventory (MBI) by K. Maslach and S. Jackson, adapted by N.E. Vodopyanova; Psychological Diagnostics of the Safety of the School Educational Environment (I.A. Baeva); Human Viability Test (E.A. Rylskaya); Method of Studying Biopsychological Age (by K.A. Abulkhanova and T.N. Berezina); Scale of Expected Retirement Age. The study involved teachers at the professionalization stage (N = 23, average age of 30.2 years) and teachers at the pre-retirement stage (N = 26, average age of 52.2 years). <strong>Results.</strong> It has been shown that the characteristics of psychological safety in the educational environment and resilience act as factors that reduce the psychological age and aging of teachers, while the indicators of professional burnout act as factors that increase them. <strong>Conclusions.</strong> Despite the multidirectional effects of the factors, the expected professional longevity of the entire sample of teachers is approaching the officially accepted values; teachers at the professionalization stage do not have any connections with the studied stresses and resources; at the pre-retirement stage, the expected professional longevity may increase if teachers are free to make their own decisions (the cognitive component of the psychological safety of the educational environment).</p></jats:p>
