Immigrant Parents' Education Level Before Coming To US Is The Most Important Factor For Predicting Their Children's Success In US: Logical Conclusion Is Adult Literacy Programs For Parents Could Improve Children's Educational Outcomes And Aid Children's Success In US

From "Parents’ education before migrating tied to children’s achievement" on ScienceBlog:

Immigrant parents’ education before migrating is more strongly tied to their children’s achievement in the United States than any other social, economic, or linguistic parental attribute, either before or after migration. That’s the conclusion of a new study in a special section of the September/October 2012 issue of Child Development on the children of immigrants.

The study was carried out by researchers at the Pennsylvania State University.***According to [Suet-ling] Pong [professor of education and sociology at the Pennsylvania State University and the study’s lead author], the results raise the possibility that adult literacy programs to increase education levels of immigrant parents could have benefits in both parents’ and children’s generations. [Emphasis added.]

See my October 25, 2010, post on this blog, "Improving Mother's Literacy Improves Disadvantaged Child's Academic Performance." A different researcher reach a similar conclusion about parent literacy programs improving the educational outcomes of children.
