[I’m not synthesizing and commenting much because I’m in data collection mode. This blog represents my online race/IQ/culture etc., notebook. Which is why many of these posts are rather disjointed — This is a follow up to Smart Blacks, 2nd Gen Black Success, 2nd Gen Black IQ, and Immigrant Selection and Regression.]
I uncovered some more data on 2nd gen US immigrant IQ/cognitive ability by race using the International Explorer. We’re interested in these scores for reasons discussed before. I’m interested specifically because 2nd gen performance was used against me in a Bell Curve argument.

TIMSS (2007) had some information. (I included s.e. and SD so you could calculate the sample size.) Math (grade 4) and Science (grade 4):
PIRLS (2006) also had some information. Reading (Grade 4):
