Pandemic Learning Loss: The Role Remote Learning Played
“In a sophisticated analysis of thousands of public school districts in 29 states, researchers at Harvard and Stanford Universities found that poverty played an even bigger role in academic declines during the pandemic.”

COVID-19 pandemic massively set back learning, especially for high-poverty areas
The COVID-19 pandemic devastated poor children’s well-being, not just by closing their schools, but also by taking away their parents’ jobs, sickening their families and teachers, and adding chaos and fear to their daily lives. The scale of the disruption to American kids’ education is evident in a district-by-district analysis of test scores shared exclusively with The Associated Press.

Students Face Massive Learning Curve After Pandemic
As the COVID-19 pandemic seems to be winding down, the average student is now half a year behind in math skills and a quarter of a year behind in reading skills, a new analysis of standardized test data shows. Districts with mostly poor students were impacted even more severely, according to the recently released Education Recovery Scorecard. “When you have a massive crisis, the worst effects end up being felt by the people with the least resources,” Stanford University researcher Sean Reardon, EdD, told The Associated Press.”

Stanford-Harvard 'scorecard' translates California's test scores into months of missed learning
A massive data project by researchers at Harvard and Stanford universities, released Friday, has converted national and state test scores into the equivalent measure of learning decline during the pandemic for every school district and student group in California and 28 other states. The interactive data in the Education Recovery Scorecard confirm, in clear and stark terms, the disparities in performance and learning loss among states, districts within states and racial, ethnic and income groups within districts for grades three to eight.
