Students from high and low socioeconomic homes have been found to make similar gains on reading during the school year (Alexander, Entwistle, & Olson, 2004). It’s what happens in the summer that contributes to a growing gap in low- and high-income students’ reading. During the summer, low-income children either fall or stagnate during the summer, while higher-income children continue to progress or maintain their reading levels. By fourth-grade, the accumulated differences over several summers are reflected in a significant gap between low- and high-income students.
