Due to the shortage of the precious resource water and the consequences of the climate change, numerous European policies have been developed and adopted for the protection and sustainable utilisation of water creating a huge demand in particular in the vocational training. Economic factors like privatisation and increasing cost pressure in water management are heightening these educational needs leading to the demand for VET (Vocational Education and Training) opportunities and products as short and tailor-made as possible. The situation of the vocational education and training in the water management will be improved by the WACOM instrument, which defines within the water sector the needed competences and qualifications for the different tasks, working places and employees for the first time. In this way WACOM aims at increasing the volume of mobility throughout Europe as well as at a higher transparency and recognition of qualifications and competences. All and in particular modular VET opportunities and products in the water management can be exactly defined concerning the addressed competences and qualifications and will become transparent and easy to select that they are accurately fitting for users.
