One way of training for your future occupation in Germany is by pursuing a dual vocational training programme. Such programmes offer plenty of opportunities for on-the-job training and work experience. Programmes usually last between two and three and a half years and comprise theoretical as well as practical elements. You will spend one or two days a week, or several weeks at once, at a vocational school where you will acquire the theoretical knowledge that you will need in your future occupation. The rest of the time will be spent at a company. There you get to apply your newly acquired knowledge in practice, for example by learning to operate machinery. You will get to know what your company does, learn how it operates and find out if you can see yourself working there after completing your training. This combination of theory and practice gives you a real head start into your job: by the time you have completed your training, you will not only have the required technical knowledge, but you will also have hands-on experience in your job. There are around 350 officially recognised training programmes in Germany, so chances are good that one of them will suit your interests and talents. You can find out which one that might be by visiting one of the jobs and vocational training fairs which are organised in many German cities at different times in the year. Employment prospects for students who have completed a dual vocational training programme are very good. This is one of the reasons why this kind of training is very popular with young Germans: around two thirds of all students leaving school go on to start a vocational training programme. 1.
