Education reporters such as Chalkbeat’s Matt Barnum continue to cling to the idea that pouring exorbitant resources into an inefficient school system can make a sustainable difference in the lives of America’s children. To support the claim, Barnum points to a couple of recent studies examining the association between court-ordered education spending increases and student outcomes.
Jackson, Johnson, and Perisco (2016) conclude that an annual 10% increase in per pupil spending for all 12 years of schooling leads to an increase of about a third of a year of completed education. Similarly, Lafortune, Rothstein, and Schanzenbach (2016) find that court-ordered spending increases improve test scores for the least-advantaged students by a little under a hundredth of a standard deviation per year.
However, both of these studies suffer from important methodological issues that limit their ability to identify a strong causal relationship between education dollars and student outcomes.
