A new study published by the National Bureau of Economic Research says that high-stakes testing leads to an increase in the incarceration rate.

Olesya Baker and Kevin Lang conclude that the use of high-stakes tests as a graduation requirement leads to a lower graduation rate and a higher incarceration rate.

Anthony Cody has an excellent column about this study here. As he puts it, “exit exams boost the school to prison pipeline.”

The recent NAEP Long Term Trend report showed almost no test score gains from 2008-2012, the era in which high-stakes tests were ubiquitous.

Please, someone, remind me why Congress and Secretary Duncan and President Obama and every governor and legislature is obsessed with testing. Is it confusion, incoherence, indifference, ignorance, or something else?
