Not all that…

[I’m not synthesizing and commenting much because I’m in data collection mode. This blog represents my online race/IQ/culture etc., notebook.

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.

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):

[PISA (2006, 2009) Math (Age 15) had some information on Hispanic and Asian performance.
