Reading... is one of the most important things you can do at home!

• After G.N.P., the quantity of books in one’s home was the most important predictor of reading performance. The greatest effect was seen in libraries of about 100 books, which resulted in approximately 1.5 extra years of grade-level reading performance. (Diminishing returns kick in at about 500 books, which is the equivalent of about 2.2 extra years of education.)
• Libraries matter even more than money; in the United States, with the size of libraries being equal, students coming from the top 10 percent of wealthiest families performed at just one extra grade level over students from the poorest 10 percent.
• The implications are clear: Owning books in the home is one of the best things you can do for your children academically. It helps, of course, if parents are reading to their children and reading themselves, not simply buying books by the yard as décor.
