The in-company apprenticeship training is part of the practical training in the trades and an important addition to the in-company training. It is necessary because, due to its small-scale structure, the craftsmanship offers very different training conditions in the individual craft enterprises. The task of ÜLU is to ensure a broad uniform basic training and specialist training at the latest technical level for every apprentice. In the basic level courses, the apprentices use the example of simple customer orders to organise workflows, to carry out work orders professionally and also to check and assess them in the end. The specialist level courses then focus on the safe handling of demanding customer orders using “high-tech” and special technologies.
