Employee competences play a significant role in the labor market, influencing the development of the global economy. Previous studies have largely focused on the management of documents confirming the competence and credibility of these documents. Carrying out an in-depth analysis of acts, vocational regulations, and government reports, a conceptual model was developed that integrates competencies and skills data description, documents and all other forms of confirmation of competence acquisition. Application of blockchain technology allows integration all data into one autonomous system while using exiting competencies ledgers. The developed IT conceptual model meets the requirements of all interested parties: employees, employers and organizations issuing such documents. The findings are of great importance for improving the effectiveness of managing information on individual competencies.
