Dr. Wai, I am curious to know what percentage of your sample 1.7 million test scores from 1981 to 2000 is by students who are children of once foreign students who came to the U.S. to pursue their advanced degrees in the early 1980's. In your study, the SAT score started to tick up in the early 1990's, which seemed to coincide with the age of many foreign-born children of those foreign students. By the late 1990's, most foreign students of the early 80's also had their U.S.-born children ready for college. My point is that immigration by skilled foreign students/workers have probably contributed to the substantial uptick to the SAT/ACT scores since 1990's, especially in math. Look around you, which high school student today who is a child of Chinese or Indian parents doesn't have a perfect or near perfect SAT Math score?
