In March 2020, a little more than three years ago, state and local politicians across America halted in-person classes for K-12 government schools with the purported aim of slowing the spread of the COVID-19 virus. When the school shutdowns began, few ordinary citizens had any idea how long they would last. It ultimately turned out that many school districts would remain closed until well into 2021. It’s been estimated that roughly half of America’s public schoolchildren lost a year or more of full-time, face-to-face instruction in the classroom.
