There has been much talk about how Finland plummeted from its traditional top spot in the PISA scores, but:
Overall, though, across all three subjects, Finland was still #1 in Europe and its diaspora.
In contrast, the Scandinavian countries did not excel in 2012, with overall means of 498 for Denmark, 496 for oil-rich Norway, and 482 for Sweden. Among members of the OECD, the rich countries` club, Sweden beat only Israel, Slovakia, Greece, Turkey, Chile, and Mexico. (Some of those countries that Sweden edged out are in the rich countries` club only for "courtesy" or "aspirational" reasons.)
