American children who go to schools with fewer than 10% of students eligible for subsidized lunch score close to the top in math tests given to 15-year-olds, just behind China, Singapore and Taiwan. But kids in schools with 25% to 50% of peers in subsidized lunch fall about 16 rungs to the lower third of developed countries.
