RALEIGH, N.C. (AP) — North Carolina’s public schools are returning to class, but most students are still having to learn at home through their computers to start the year due to continued worries about COVID-19.

Nearly every school in all K-12 districts begin classes Monday. Under Gov. Roy Cooper’s plan, school boards could start the year with full remote learning, hold in-person instruction with strict social distancing or provide a mix.

Districts and charter schools that teach about two-thirds of the 1.5 million public school students chose the full-remote option for now, according to data from the Department of Public Instruction.

Schools were closed in March amid the pandemic and never reopened this past year.

School districts are expanding their online instruction. More than half of Wake County’s school enrollment signed up for the district’s “virtual academy.” However, the State Board of Education declined last week to increase enrollment for two virtual charter schools.
