The Washington Post looks at Finland's education system (seen via Gary Farber):

Finland finishes first in the Program for International Student Assessment (PISA) exams that test 15-year-olds in all of the world's industrial democracies. Finland also finishes at or near the top in many global comparisons of economic competitiveness: Internet usage, environmental practices and more. Finland, where the modern cell phone was largely invented, has more cell phones per capita than any other nation -- nearly 85 per 100 citizens.

As recently as the 1970s, Finland required that children attend school for just six years and the education system here was nothing special. But new laws supported by substantial government spending created, in barely 20 years, a system that graduates nearly every young person from vocational or high school, and sends nearly half of them on to higher education. At every level, the schooling is rigorous, and free.

Wouldn't that mean the Finnish cell phone industry, for example, was built by people who had done all or most of their education before the current system was set up?

By the way, are the PISA tests administered by the Finnish schools or by impartial observers?
