Congress set aside approximately $13.2 billion of the $30.75 billion allotted to the Education Stabilization Fund through the Coronavirus Aid Relief, and Economic Security (CARES) Act for the Elementary and Secondary School Emergency Relief Fund (ESSER Fund). Signed into law on March 20, 2021, the Department awarded these grants ­to State educational agencies (SEAs) for the purpose of providing local educational agencies (LEAs), including charter schools that are LEAs, with emergency relief funds to address the impact that COVID-19 has had, and continues to have, on elementary and secondary schools across the Nation.
