From the paper: "Our findings highlight the challenges that recovery efforts faced during the 2021–22 school year. Although, on average, math and reading test score gains during the school year reached the pace of pre-pandemic school years, they were not accelerated beyond that pace. In the districts where we had detailed data on student participation in academic interventions, we found that recovery efforts often fell short of original expectations for program scale, intensity of treatment, and impact. Our findings on the pace and trajectory of recovery and the challenges of implementing recovery initiatives raise important questions about the scale of district recovery efforts."
