The COVID-19 pandemic forced America's public schools to close in the latter half of the 2019-20 school year. Schools' reopening plans vary for 2020-21. We reviewed the reopening plans for all 50 states, as well as the largest 120 school districts in the United States with a particular focus on reopening modalities, mask-wearing guidance, the treatment of vulnerable students and staff, and fall sports. Several states recommend that schools reopen based on viral spread, while others recommend a particular modality (in-person, hybrid, or remote instruction). States varied most in their treatment of fall 2020 athletics. This descriptive work represents a first step in understanding how schools are reopening amidst the COVID-19 pandemic. We conclude with implications for school choice policy.
