I don’t really find it strange, if anything a slavish obsession to test scores strikes me as strange. School is just an artificial institution like any other, it’s not as if getting good grades is equivalent real-world success or “true” intelligence.
The US also has the best universities in the world, by and large, (even if the regular education system is lacking), so I am pretty skeptical of the idea that raw test scores as the sole criterion would lead to better outcomes.
