Covid-19 and Inequality between Low- and High-Achieving Students

If school closures and social-distancing experiences during the Covid-19 pandemic impeded the development of children’s cognitive and socio-emotional skills, they may leave a lasting legacy in human capital. The available evidence suggests that unless remediated, the school closures will persistently reduce skill development, lifetime income, and economic growth and increase inequality. 

Low-achieving students may be particularly affected by the lack of educator support during school closures. Based on detailed time-use information, we find that while students on average reduced their daily learning time of 7.4 hours by about half, the reduction was significantly larger for low-achievers (4.1 hours) than for high-achievers (3.7 hours). Low-achievers disproportionately replaced learning time with detrimental activities such as TV or computer games rather than with activities more conducive to child development. The learning gap was not compensated by parents or schools who provided less support for low-achieving students.
