From the report: "Nearly every state is using a portion of the $19 billion in federal Elementary and Secondary School Emergency Relief funding set aside for state use to provide targeted supports around instruction and acceleration in math. CCSSO’s latest Road to Recovery report highlights five investment priorities for math acceleration: high-quality instructional materials, professional development, diagnostic and assessment tools, high-impact tutoring and out-of-school time programs. These investments are already starting to demonstrate an impact on participating students, though sustained work is needed to maintain this momentum and close all COVID-19 pandemic-related learning gaps."
