Immigrant Students Lag, but Less So in U.S.: "Immigrant 15-year-olds in the United States don't do as well in math, reading or science as native-born children, and many have only basic skills, a study finds. But immigrants aren't as far behind in the U.S. as they are in some other major nations.
The findings are based on the Program for International Student Assessment, a test that measures the literacy of 15-year-olds and how well they apply skills to the real world. It is given to students in many industrialized countries and considered an international benchmark."
