As a part of the international project "SKILLCO - Skills sector alliances for transfer of knowledge and skills of VET workforce in construction" we have prepared a survey which aims to identify skill gaps in various areas of work in the construction industry. The aim of the project is to identify and define the 4 most common skill gaps for workers with secondary vocational education in construction, which are common to all partner countries (Germany, Hungary, Belgium and Slovenia) and integrate them into the curriculum of vocational secondary education. On this basis we will prepare short programs of staff training, to contribute to improving competitiveness and facilitating the transition of employees of construction workers in the common European labour market.
