High school students who were in distance learning during the Covid-19 pandemic suffered socially, emotionally and academically, according to a study published by the Education Research Association.

The study compared students who studied remotely and their counterparts who studied in person. Students who studied at home scored slightly lower on the “thriving index” than students who went to school in-person.

The differences were not great, but even small effects are noteworthy when they impact millions of people, according to a press release on the report.
