Jörg Krummenacher reports in the NZZ that roughly 20% of a cohort graduate from Switzerland’s most academic type of high school (Gymnasium). In the canton of St. Gallen, only 13% do. Not surprisingly, these St. Gallen high school students do well in standardized PISA tests.

Also, running one additional class of students in high school costs nearly 500 000 Swiss Francs per year. About 80% of St. Gallen pupils entering Gymnasium graduate with the “Matura.”
