"Halt education chaos!"  headlines Der Spiegel, pleading for a unified educational system. The Hamburg weekly argues that Germany, which has as many education systems as federal states (16), is bogged down in educational idiosyncrasies that are imperilling its most important resources: brains and expertise. Between secondary education in Bavaria, eternally top of the list, and Berlin (15th place), teacher training, as well as the quality, content and duration of classes, fluctuate wildly. Result: parents living in poorly-rated states send their children to more highly-reputed ones, or pay for private schools.
