Summer learning is a research-based strategy shown to help prevent summer learning loss and support students who may be below grade level to grow before the next school year. Summer learning is also appropriate for all students to accelerate learning. This strategy is particularly important in the summer of 2021 as states, districts, and schools seek to curtail potential learning loss from the COVID-19 pandemic. This planning guide was inspired by the investment that Tennessee has made in summer learning through the summer Read to be Ready program and recent legislation targeted at COVID-19 related learning loss. The guide was specifically developed to assist districts participating in the Tennessee Rural Acceleration and Innovation Network (TRAIN) as they began to plan for their summer learning camps. This guide should be used to assist education leaders in thinking through, planning for, and making the decisions that will ensure opportunities are successful for students, families, and teachers. The planning guide begins with an overview of recent research findings that highlight effective small group and summer learning practices. It then provides space for leaders to focus on some of the most important questions, decisions, and next steps to implement high-quality summer learning opportunities.
