Analysis in mid-April 2020--in the early throes of the pandemic--found that less than 25 percent of low-income countries were providing any type of remote learning, while close to 90 percent of high-income countries were. On top of cross-country differences in access to remote learning, within-country differences are also staggering. For example, during the COVID-19 school closures, 1 in 10 of the poorest children in the U.S. had little or no access to technology for learning. The authors believe that strong and inclusive public education systems are essential to the short- and long-term recovery of society and that there is an opportunity to leapfrog toward powered-up schools. To achieve this vision, they propose five actions to seize the moment and transform education systems (focusing on pre-primary through secondary school) to better serve all children and youth, especially the most disadvantaged.
