The children of East Asian immigrants perform better than the children of white Americans. How does the language hypothesis you put forth account for that?
1. We don't know that. We know that Asian Americans outperform whites, but Asian American can refer to 1st, 2nd, 3rd etc... generation immigrants.
2. Asian immigrants tend to learn the prestige dialect (the dialect the SAT is written in), so if their children are native English speakers, they tend to learn that dialect natively.
4. Language differences are a factor in performance but obviously not the only factor or the largest factor.
Key stats: Asian American population in 2015 is slightly more than 20 million. In 1960 it is about 1 million and only about 2.5 million in 1980.

Is it somehow easier for Asian immigrants to learn the prestige dialect than Hispanic immigrants?
None of that shows the rate at which Asian Americans take the SAT, the birth rates of 2.5 million Asian Americans who were here in 1980, or the ages of the Asians who've immigrated since. So saying that we have an extra 17.5 million Asian Americans, and Asian Americans outperform whites on the SAT, therefore 2nd generation Asian Americans outperform whites isn't supported by the evidence presented so far.
However none of that really matters because you ignored my last point.
Other factors such as family income are larger factors that native language.
>Is it somehow easier for Asian immigrants to learn the prestige dialect than Hispanic immigrants?
If it's easier is irrelevant because Asian Americans are more likely to speak the prestige dialect than Hispanics. But to answer your question, yes it is eaiser because Asians have much higher incomes, and they integrate with white communities faster--at least in part because Asian communities are smaller and more spread out.
Yeah, and my original point was that these tests don’t discriminate based on skin color or ancestry. What you’re saying is that different races have different aggregate outcomes, but that that is due to different aggregate income levels. That doesn’t really sound like you disagree with my original point.
No. I'm saying that income plays a larger role than dialect. Dialect still plays a role. If dialect differences were accounted for, speakers of non-standard dialects would have greater aggregate scores.
