That’s the question posed in a new working paper by Patricia M. Anderson, Kristin F. Butcher, and Diane Whitmore Schanzenbach.

For example, schools may cut back on recess and physical education in favor of increasing time on tested subjects.” Caveats apply, but the scholars find that “schools that were on the margin of passing have about a 0.5 percentage point higher rate of overweight in the following year.”
