From the brief: "This brief is one in a series aimed at providing K-12 education decision makers and advocates with an evidence base to ground discussions about how to best serve students during and following the novel coronavirus pandemic. This brief looks at potential interventions for students who have fallen out of typical grade range – particularly those who were struggling before the pandemic. Evidence suggests that, although most students will experience some learning loss, the majority will still be able to engage with grade-level content."
