Universities in Germany are part of the free state education system, which means that there are very few private universities and colleges like Munich Business School for example. While the organizational structure claims to go back to the university reforms by Wilhelm von Humboldt in the early 19th century, it has also been criticized by some (including the German-born, former Stanford University president Gerhard Casper) for having an unbalanced focus, more on education and less on research, and the lack of independence from state intervention. Many of today's German public universities, in fact, bear less resemblance to the original Humboldt vision than, for example, a typical US institution.German university students largely choose their own programme of study and professors choose their own subjects for research and teaching. This elective system often results in students spending many years at university before graduating, and is currently under review. There are no fixed classes of students who study together and graduate together. Students change universities according to their interests and the strengths of each university. Sometimes students attend two, three or more different universities in the course of their studies. This mobility means that at German universities there is a freedom and individuality unknown in the USA, the UK, or France. next 2, 3
