From the brief: "The decline in public school enrollment during the COVID-19 pandemic as many school districts switched to fully remote or hybrid instruction has been a major cause for concern in the United States. A recent analysis by the National Center for Education Statistics reveals that total K–12 enrollment dropped by 3% nationwide in 2020–21 compared to the previous school year. The primary objectives of this study were to better understand these enrollment trends in four states (California, Florida, Texas, and Washington), the extent to which the trends differ across different school settings, and the factors that are associated with these enrollment trends. In particular, the brief examined the overall enrollment trends in these four states along with breakdowns by grade, race/ethnicity, and school characteristics."
