This brief is one in a series aimed at providing K-12 education decision-makers and advocates with an evidence base to ground discussions about how to best serve students during and following the novel coronavirus pandemic. It begins with an at-a-glance view of an effective voluntary academic summer learning program structure (duration, class size, attendance, enrichment activities, academic curriculum) and personnel (academic teachers, enrichment instructors, and administration). Next, it provides the evidence base that supports instituting voluntary academic summer learning programs. Then a more in-depth look at the program structure and personnel of effective programs is offered. Lastly, the brief includes a section on summer programming caveats and considerations.
