Descriptive statement of the study design: an observational examination of "seven school districts across the state," comparing district incidence trends for students and staff with local community trends during fall 2020. No sample sizes or effect sizes are printed in the available text.

"Mathematica identified seven school districts across the state to examine whether COVID-19 incidence trends for students and staff in Pennsylvania school districts using hybrid instruction paralleled or exceeded trends in the local community during the fall of 2020."

Discussion¶

Related Claims¶

• COVID-19 school closures in Pennsylvania are likely to have caused substantial learning losses, with harms concentrated in populations also disproportionately harmed by the disease — related
• In Pennsylvania districts using hybrid instruction with precautions in fall 2020, increases in student and staff infections were no greater than community increases outside school — possibly the same claim (merge candidate)
• The report examined value-added implementation in seven school districts or states — related
• Hybrid approaches with smaller masked groups attending part-time dramatically reduce total likely infections, and most outside infections produce zero additional in-school infections — related
• Requiring masks measurably reduces infection spread in schools, according to simulation models of school operating strategies — related
• Reducing student density in classrooms and shared school spaces, combined with precautions such as physical distancing, some mask wearing, and good ventilation, allows for a safer school reopening during COVID-19 — related
