There is a big difference between different immigrant groups. In the U.S., children of immigrants are also often the lowest performers. The U.S. tracks test scores by race and not immigration status. But looking at test scores for hispanic students is a rough proxy because more than 60% of hispanic students are immigrants or the children of immigrants: https://www.equityinhighered.org/indicators/secondary-school.... That means they probably grew up in a household where their parents weren’t native english speakers.

My comment did not preclude either of these from being true. I didn't say "On average, children of immigrants do better in the US." I said "often the highest performers are children of immigrants."

Looking at the test scores for Asians is also a rough proxy of children of immigrants, and you can see what your link shows: They are the lowest of all groups in being "below average", and the highest of all groups in the top category ("Advanced") - over double the next highest race in math, for example.

I expected better reasoning from you, given the whole "Asian and child of immigrants" ;-)

(As an aside, not sure how relevant your link is, given that it's from 2015, and the thread is about the shift from 2015 to now).
