Paul von Hippel, of the Lyndon B. Johnson School of Public Affairs at the University of Texas at Austin, said he and colleagues were unable to prove results from a 30-year-old study that indicated achievement gaps between students from low-income homes and those from higher-income families grow during the summer. Data shows that summer learning can help shrink existing gaps, but those gaps were likely in place when the students entered kindergarten, von Hippel writes.
