““Tracking in elementary school was a uniquely American policy. The sorting began at a very young age, and it came in the form of magnet schools, honors classes, Advanced Placement courses, or International Baccalaureate programs. In fact, the United States was one of the few countries where schools not only divided younger children by ability, but actually taught different content to the more advanced track. In other countries, including Germany and Singapore, all kids were meant to learn the same challenging core content; the most advanced kids just went deeper into the material.””
