Officials at the New York State Education Department on Thursday released an updated guidance for schools reopening in New York amid growing uncertainty surrounding the spread of the highly contagious COVID-19 delta variant. 

The guidance also comes after the state Department of Health earlier this month signaled the details of reopening would be largely left to local school districts and public health officials at the country level. 

“As we prepare for schools to reopen in September, our priority must be to provide leaders with access to information about practices that have proven effective throughout the pandemic,” said Chancellor Lester W. Young in a statement. “The Department’s health and safety guide is a concise resource that will assist districts as they mitigate risks to the health and safety of students, teachers and school staff while providing flexibility for schools to address their own unique circumstances in a manner that best meets the needs of all students.”

Questions remain for schools and school district leaders with children returning to the classroom. Children younger than 12 do not yet qualify for the COVID-19 vaccine. Lt. Gov. Kathy Hochul, who is set to become governor in 12 days, said earlier on Thursday she expects there to be a mask mandate in place for schools by next month. 

“At a time when schools are preparing to reopen and the COVID positivity rate is increasing, we must ensure our schools and districts have the most up-to-date resources and mitigation strategies available to keep our children and school staff safe,” said Commissioner Betty A. Rosa. “Reopening amidst a pandemic for the second consecutive year is truly a daunting task. Our hope is that this guide, coupled with the input of local health officials will help the state’s education community as they prepare for September.”

The guidance issued on Thursday largely embraces what the Centers for Disease Control and Prevention as well as the American Academy of Pediatrics have recommended for schools, including the wearing of masks indoors, regardless of vaccination status.
