Minnesota, for example, suggests fully in-person classes if a county’s two-week case rate is no higher than 10 per 10,000 people. In Pennsylvania, it’s considered safe if a county’s positive virus tests average lower than 5% for a week…
…In New York, Democratic Gov. Andrew Cuomo has said schools can reopen in areas where the average rate of positive tests is below 5% during a two-week period. But in New York City, Mayor Bill de Blasio has said schools can open only if the rate is below 3%.
Republican Gov. Kim Reynolds of Iowa, meanwhile, has ordered all schools to provide at least half of their instruction in-person unless they are granted a waiver from the state. Under her policy, schools are exempt from classroom instruction only if their county’s test rate is 15% or higher, and if at least 10% of students are absent.
