The paper "The well-being a fundamental indicator in the didactic activity" focuses on the theoretical foundation of the concept of well-being, on the fundamental components necessary for maintaining and improving the well-being, which can contribute to generating the capital value of the society, leading to the formation through education of the mental infrastructure of the Romanian society in accordance with the global culture of contemporary society. This dimension requires the intensification of the preoccupations in the educational act by harmonizing the intellectual education with the socio-emotional education, which can generate the well-being of a learner and can ensure a high school performance. It aims to develop the personality of a student's identity in balance with cultural diversity and global policy trends. At the intersection between social, economic and cultural, educational policy is built, in a more complex analytical context, sustained by a set of interests that have generated metamorphoses in the social system, but also in the educational approaches. This state of well-being, which the individual feels leads to the promotion of a prosocial behaviour, a healthy lifestyle, time and information management, thus preventing and combating undesirable behaviours in our society that can affect well-being in social, professional and familiar relationships. Through this study, the question arises whether the objective of well-being is promoted at the level of educational action agents in view of effective psychosocial functioning of educational relations.
