This resource  by the Learning Policy Institute provides guidance on how states and local governments should spend federal funds provided through the Elementary and Secondary School Emergency Relief Fund (ESSER) as part of the larger Coronavirus Response and Relief Supplemental Appropriations Act (CRRSAA). The resource shows that there are currently 100,000 teaching positions that are either vacant or staffed by an underqualified teacher. In addition, there has been a 30% decline in enrollment in education preparation programs (EPPs) over the past 10 years. The resource urges state and local governments to use the $176.3 billion to address teacher shortages by investing in educator preparation programs, including teacher residencies and special education preparation programs.
