"The National Summer Learning Project, launched by the Wallace Foundation in 2011, includes an assessment of the effectiveness of voluntary, district-led summer learning programs offered at no cost to low-income, urban elementary students. The study, conducted by RAND, uses a randomized controlled trial and other analytic methods to assess the effects of district-led programs on academic achievement, social-emotional competencies, and behavior over the near and long term. All students in the study were in the third grade as of spring 2013 and enrolled in a public school in one of five urban districts: Boston; Dallas; Duval County, Florida; Pittsburgh; or Rochester, New York. The study follows these students from third to seventh grade; this report describes outcomes through fifth grade. The primary focus is on academic outcomes but students' social-emotional outcomes are also examined, as well as behavior and attendance during the school year." --Publisher's website.
