At a Berufsschule (vocational school), you learn the skills and knowledge you need for your vocational training. At the same time, you complete practical training at a company or organization. This type of training is called "duale Ausbildung" (dual vocational training) or "betriebliche Ausbildung" (company-based vocational training).
In Berlin, many Berufsschulen (vocational schools) are called Oberstufenzentrum (OSZ).
