In the first three years of life, Hispanics fall behind in cognitive skills

Heather McDonald nails it on education and Hispanic immigration:

A forthcoming study on Hispanic children’s cognitive skills underlines the challenges the country faces in aspiring to close the achievement gap between these children and their white and Asian counterparts. Hispanic “children fall behind their peers in mental development by the time they reach grade school, and the gap tends to widen as they get older,” reports the New York Times. “The drop-off in the cognitive scores of Hispanic toddlers, especially those from Mexican backgrounds, was steeper than for other [low-income] groups and could not be explained by economic status alone. . . . From 24 to 36 months, the Hispanic children fell about six months behind their white peers on measures like word comprehension, more complex speech and working with their mothers on simple tasks.” ...

But the more interesting implications of the study and others like it are for immigration policy. Our de facto immigration policy is currently weighted to a population that appears to require massive additional government education spending — even before formal schooling begins — to be made academically competitive. This choice would not seem to be economically rational, at least so long as we aspire to universal college-going. If the country remains committed to sending a far greater number of students to college, as even many conservatives continue to be, we better get ourselves a different mix of immigrants if we don’t want to bankrupt our education budgets. Alternatively, if the open-borders lobby prevails and Latin American migration continues to dominate our immigration flows, it’s time to acknowledge that many students never will be college material, nor do they need to be to lead productive, fulfilling lives.
