Every year I find myself reading some number of articles calling for an end to summer vacation–the practice of giving kids a summer break from school. The argument is typically made with an appeal to the the “summer learning loss” or “summer slide”, the tendency for kids to learn less during the summer than they do while in school, or even to regress academically. Adding further fuel to the argument is the tendency for the achievement gap, the difference in academic performance between higher and lower income students, to expand during the summer months. Opponents of summer vacation deem it an anachronism from a more rural, less air-conditioned age, and think we ought to do away with it altogether. Today, I seek to challenge these views.
