In this one volume, William “Bill” Jeynes has conducted massive meta-analyses related to the achievement gap in the U.S.; he has drawn from multiple disciplines; and even offers us a surprising view of history starting before the nation’s founding. In this one text, Jeynes provides the richest and most complete picture of the factors related to the U.S. achievement gap. He reveals factors some of which we commonly know and others that will surprise the reader. There simply is no better source for understanding the troubling U.S. achievement gap. He concludes by thinking afresh about our taking on a transdisciplinary assault, pulling all the actors together.
