See Is It Safe to Reopen Schools? These Countries Say Yes by Bojan Pancevski and Naja Dandanell of The WSJ. Excerpts:

"A number of countries that have reopened schools in the past two months have reported no resulting increase in coronavirus infection rates, an encouraging sign for authorities around the world that are contemplating how and when to safely bring children back to the classroom."

"Researchers and European authorities said the absence of any notable clusters of infection in reopened elementary schools so far suggested that children aren’t significant spreaders of the new coronavirus in society."

"Denmark, Austria, Norway, Finland, Singapore, Australia, New Zealand and most other countries that have reopened classrooms haven’t had outbreaks in schools or day-care centers.

"In Denmark, the opening of schools had no impact on the progress of the epidemic"

"Denmark became the first Western country to reopen schools on April 15 and maintains a sophisticated monitoring system to detect any increase in infection and identify its source.

“Our interpretation is that it may be that the children aren’t that important for the spread of infection,” Dr. Krause said. Infections in Denmark among all age groups have been decreasing since schools reopened, she added."
