From the brief: "The first full school year after the pandemic began came with dramatic changes to student enrollment and mobility in Virginia’s public school system. Enrollment dropped significantly with the greatest declines among pre-kindergarten and kindergarten students, White students, and students not classified as economically disadvantaged. As a result, the overall composition of the statewide student population in fall 2020 became slightly older, less white, and more economically disadvantaged. Although we document these patterns, we are not yet able to provide clear explanations for them."
