[THIS IS THE SECOND ENTRY IN MY WEEKLY SERIES]
I’m not alone in my concerns over the achievement gap and educational equity more generally. I have, however, felt for a while now that among the many articles and reports I’ve read on these matters, the most convincing is this one. Schools, Achievement, and Inequality: A Seasonal Perspective, written by Alexander, Entwistle & Olsen in 2001, tells a compelling empirical tale of the cumulative effects of two phenomena: differences in school readiness and summer learning loss. As the simple chart below shows (the data are made up), by the time low income students reach school age, they trail their higher income counterparts with respect to student achievement. Over the course of subsequent school years, the schools serve all students equally well (i.e. the slopes of the achievement lines are equivalent from Fall to Spring). Then, over the summer, higher income students demonstrate slight achievement gains (not nearly as much as during the school year) while low income students make no gains (nor do they necessarily suffer learning loss). The result, over time, is that the achievement gap between low- and high-income students expands over time, though that widening can be attributed mostly to “out-of-school” factors.
So, the policy implications are fairly clear: if we are serious about narrowing the achievement gap, we need to fund universal pre-K programs, and seriously consider either funding summer programs for low-income students or, more radically, think about year-round schooling. Schooling according to the agrarian calendar has run its course?
