This Master’s thesis project is commissioned by Hyria Education. Hyria Education is a multidisciplinary educational institute providing Vocational Education and Training. It operates in the Hyvinkää – Riihimäki region. The aim of this thesis is to explore whether and how the personnel’s inter-nationalization competences can be developed through staff mobility. The commissioner have long and proofed traditions in student mobility, but as the operating environment changes, there is now an apparent need for staff mobility as well. Hyria Education wants to be ready to meet the require-ments of work life as it becomes more globalized and to support the inter-nationalization at home of its VET learners. This requires new skills and competences from the staff. The main research question to be answered in the Master´s thesis is: How to develop personnel’s internationalization competences through staff mobility? In order to answer this question the internationalization competences first needed to be defined and then inspected whether they can be acquired through the staff mobility. The contribution to the Hyria Education was to make a suggestion of a new staff mobility process including guidelines for individual staff members and to create a clear procedure for the staff mobility in the Hyria Education organization. The procedure is created based on the findings made in literature and earlier research as well as on the results of conducted unstructured interviews. The project in whole is a qualitative driven mixed methods research that includes both primary and secondary data. The thesis project was successful and a suggestion for the new staff mobil-ity procedure is represented in the report. However, the new procedure is not yet tested. Before taken to full use, the procedure still needs to be add-ed with detailed forms and other supportive materials.
