摘要:Nowadays, sustainability issues are gaining more and more topicality in the context of improving organizational processes, including in the field of conformity assessment. In the field of certification of persons, competence assessment institutions have also become interested in using new approaches as the quality of assessment execution does not fully meet the requirements of stakeholders regarding the ability of a person to apply the acquired knowledge and skills in situations related to the professional activity. The aim of the research is to analyze the aspects of professional competence assessment related to the certification of persons and its performance according to the stakeholder requirements in order to develop a new sustainable approach to the process of certification of persons that would ensure the quality and reliability of its execution. Qualitative and quantitative research methods have been used to analyze the elements of the concept of certification of persons and the main elements of the concept of professional competence. As a result of the research, a new sustainable approach to certification of persons is offered, where certification of persons transforms from a conformity assessment procedure into a professional competence assessment process and ensures that a person’s ability is assessed not only in accordance with the industry requirements, but also with the stakeholder needs.
