In Germany, there are many interesting and promising options for advanced training, which can provide an opportunity quickly to obtain a good specialty that is in demand in Germany.
First, there are a large number of so-called vocational training courses (dt. Weiterbildungskurse), which issue state-style certificates of successful completion of these courses. These certificates are valid for employment in Germany. Such vocational training courses can last from 3 months to 2 years and can even sometimes be a substitute for a full-fledged university diploma. The cost of such courses ranges from a few thousand euros to 25,000 euros per course.
Secondly, there is another type of advanced training in Germany called Nicht-konsekutive Masterstudiengänge in German universities. These master's programms allow you to get an additional, more promising specialty, regardless of the previous specialty that a person received at the bachelor's or master's degree. The disadvantage of this form of advanced training is only the cost of such education, because this form of education is usually not free.
The third possible form of vocational training courses in Germany is professional development at the company where you work. Usually, large companies in Germany have their own training courses for their employees. These courses are usually free of charge and they give employees of German enterprises the opportunity to improve their qualifications for free and, due to this, to advance up the career ladder at this enterprise.
