The story emerging in our sample of districts is consistent with the bleak national economic picture, where over the four year period ending in 2011, the number of students receiving support increased 17 percent across the country. It's unlikely the 2009 numbers represent the peak for the hardest hit districts — even worse news is probably yet to come.
To the host of concerns these disturbing numbers bring to mind—few districts are prepared to add services in the current economic climate—we add another raised by Stanford University's Sean Reardon. Reardon's research shows that the income achievement gap (defined as the difference in performance between students at the 90th and 10th percentiles of income) has increased by more than 30 percent in the last 25 years and is now twice as large as the black and white achievement gap.
Surprisingly, Reardon finds that the income achievement gap increase has not been primarily driven by rising income inequality; rather, the increase is due to increasing parental involvement and investment in their children's development, particularly among families in the upper half of the income distribution. In other words, "a dollar of income appears to buy more academic achievement that it did several decades ago."
With an increasingly tight relationship between income and education, more children from families with declining and stagnant incomes should keep many an education reformer up at night. The current tea leaves don't bode well for closing the achievement gap in the coming years.
