Since the 1980s, the main driver of Finnish education policy has been the idea that every child should have exactly the same opportunity to learn, regardless of family background, income, or geographic location. Education has been seen first and foremost not as a way to produce star performers, but as an instrument to even out social inequality.

In the Finnish view, as Sahlberg describes it, this means that schools should be healthy, safe environments for children. This starts with the basics. Finland offers all pupils free school meals, easy access to health care, psychological counseling, and individualized student guidance.

In fact, since academic excellence wasn’t a particular priority on the Finnish to-do list, when Finland’s students scored so high on the first PISA survey in 2001, many Finns thought the results must be a mistake. But subsequent PISA tests confirmed that Finland — unlike, say, very similar countries such as Norway — was producing academic excellence through its particular policy focus on equity.

That this point is almost always ignored or brushed aside in the U.S. seems especially poignant at the moment, after the financial crisis and Occupy Wall Street movement have brought the problems of inequality in America into such sharp focus. The chasm between those who can afford $35,000 in tuition per child per year — or even just the price of a house in a good public school district — and the other “99 percent” is painfully plain to see.
