While a nation of burned-out, involuntary home schoolers slogs to the finish line of a disrupted academic year, a picture is emerging of the extent of the learning loss among children in America, and the size of the gaps schools will be asked to fill when they reopen.

Chronic absenteeism is a problem in American education during the best of times, but now, with the vast majority of the nation’s school buildings closed and lessons being conducted remotely, more students than ever are missing class — not logging on, not checking in or not completing assignments. The absence rate appears particularly high in schools with many low-income students, whose access to home computers and internet connections can be spotty.
