To substantiate the modern model of professional competences of healthcare workers based on expert modelling of labour functions in a professional standard as a basic element of the system of assessment of their qualifications and continuing professional development. In the system of healthcare professionals' training, a prognostic approach to designing a structural and functional model of a specialist remains the main one. Using the analysis of modern data on the relations between the labour market and the system of doctors' professional training, the pragmatic (actualisation) model of professional competences is substantiated. The latter is based on the analysis of experts who observe the actual work of doctors in real conditions, build their expert opinion on the basis of self-reflection and analysis of their own professional experience. In contrast to the prognostic model, this model can be used as a basis for the formation and assessment of professional competences of healthcare professionals, in particular those acquired through non-formal and informal education based on constructivist learning principles. The features of the pragmatic (actualisation) model of doctors' professional competences are as follows: methodological reliance on constructivism; expert method of forming the content of labour actions and competences; results of professional self-reflection of healthcare professionals; fixation of professional competences in professional standards by medical specialities; evaluation of the results of non-formal and informal learning; analysis of current labour market information, up-to-date descriptions of activities in the workplace and relevant job functions; realism and pragmatism. In order to develop the National Qualifications System in the field of healthcare, it is necessary to implement the following: implementation as regulated by the current legislation of the procedures for assessment of formal, non-formal and informal results of professional training in the system of continuing professional development; development of professional standards for all specialities of healthcare professionals — doctors, nurses, pharmacists and managers of healthcare facilities; development of a system of independent qualification centres in the healthcare sector.
