The national average of SAT scores had been virtually level for at least
10 years (varied from 965 to 980) until 1963 when the Supreme Court
decisions were made, and in the next 11 years the scores plummeted to
908. In 1974, the declining curve shallowed out, and in 1980, the curve
reversed and began to climb. This was the time period during which the
private Christian school movement exploded. Barton attributed the
reversal to the 10% of the nation's students who were now being educated
under "divine law." He pointed out that these were not the most
affluent families who were taking this option.

That strikes me as a weak point.
