About half of school-age children in the United States will attend school remotely, according to a survey by Burbio.com.

Roughly 52 percent of students are expected to be learning in virtual classrooms at the beginning of the school year, while 44 percent will be attending school in person. Of the students attending in person, some are attending every day and others are attending only a few days of the week. About 4 percent of school districts in the United States have not finalized plans.

"We expect this situation to stay fluid for the entire academic year and we will continue to measure it," said Julie Roche, Burbio.com co-founder. Roche also said that if COVID-19s reached each particular district's threshold, it could result in certain districts revisiting or converting back to online learning, or resume in-person learning if COVID-19 levels drop in an area.
