…reveal the United States to be treading water in the middle of the pool. In math, American teenagers performed slightly worse than they usually do on the PISA — below average for the developed world, which means they scored worse than nearly three dozen countries. They did about the same as always in science and reading, which is to say average for the developed world.
But that scoreboard is the least interesting part of the findings. More intriguing is what the PISA has revealed about which conditions seem to make smart countries smart. In that realm, the news was not all bad for American teenagers.
The good news is that–although “the United States had not raised its average scores”–its
measures of equity…had improved. One in every three disadvantaged American teenagers beat the odds in science, achieving results in the top quarter of students from similar backgrounds worldwide.
This is a major accomplishment, despite America’s lackluster performance over all. In 2006, socioeconomic status had explained 17 percent of the variance in Americans’ science scores; in 2015, it explained only 11 percent, which is slightly better than average for the developed world. No other country showed as much progress on this metric. (By contrast, socioeconomic background explained 20 percent of score differences in France — and only 8 percent in Estonia.)
But what countries had the best outcomes overall?
Generally speaking, the smartest countries tend to be those that have acted to make teaching more prestigious and selective; directed more resources to their neediest children; enrolled most children in high-quality preschools; helped schools establish cultures of constant improvement; and applied rigorous, consistent standards across all classrooms.1
Of all those lessons learned, the United States has employed only one at scale: A majority of states recently adopted more consistent and challenging learning goals, known as the Common Core State Standards, for reading and math. These standards were in place for only a year in many states, so Mr. Schleicher did not expect them to boost America’s PISA scores just yet. (In addition, America’s PISA sample included students living in states that have declined to adopt the new standards altogether.)…Standards like the Common Core exist in almost every high-performing education nation, from Poland to South Korea.
