In elementary schools, CDC recommends all students remain at least 3 feet apart in classrooms where mask use is universal — regardless of whether community transmission is low, moderate, substantial, or high.
In middle and high schools, CDC also recommends students should be at least 3 feet apart in classrooms where mask use is universal and in communities where transmission is low, moderate, or substantial.
Middle school students and high school students should be at least 6 feet apart in communities where transmission is high if cohorting is not possible. Cohorting is when groups of students are kept together with the same peers and staff throughout the school day to reduce the risk for spread throughout the school. This recommendation is because COVID-19 transmission dynamics are different in older students – that is, they are more likely to be exposed to SARS-CoV-2 and spread it than younger children.
