Under the American Rescue Plan (ARP), which became law in March 2021, school districts around the country will receive funding to address the impact of COVID-19 on students' academic, social, emotional and mental health needs. This funding is known as "ESSER III."
"ESSER" is short for Elementary and Secondary School Emergency Relief. ESSER III receives its numerical designation from the fact that the ARP ESSER Fund is the third set of COVID-related federal relief grants for schools that Congress has passed since the pandemic began.
ESSER I and ESSER II were established respectively by the Coronavirus Aid, Relief, and Economic Security (CARES) Act in March 2020 and the Coronavirus Response and Relief Supplemental Appropriations (CRRSA) Act in December 2020.
