By age 10, the gap is three years. By then, some poor children have not mastered basic reading and math skills, and many never will: this is the age at which failure starts to become irreversible.
A few school systems seem to have figured out how to erase these gaps. Finland ensures that every child completes basic education and meets a rigorous standard. One Finnish district official, asked about the number of children who don’t complete school in her city, replied, “I can tell you their names if you want.” In the United States, KIPP charter schools enroll students from the poorest families and ensure that almost every one of them graduates high school—80 percent make it to college. Singapore narrowed its achievement gap among ethnic minorities from 17 percent to 5 percent over 20 years.
