National and international guidelines differ about the optimal physical distancing between students for prevention of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission; studies directly comparing the impact of ≥3 versus ≥6 ft of physical distancing policies in school settings are lacking. Thus, our objective was to compare incident cases of SARS-CoV-2 in students and staff in Massachusetts public schools among districts with different physical distancing requirements. State guidance mandates masking for all school staff and for students in grades 2 and higher; the majority of districts required universal masking.
