This is the technical appendix to the research brief titled, “From loss to recovery: Diverging paths and uneven gains across schools,” which examines two components of school recovery post-COVID pandemic to better understand recovery patterns.

This research brief examines two components of school recovery post-COVID pandemic to better understand recovery patterns. These include initial declines in average achievement and post-pandemic gains in average achievement across schools. By understanding these different recovery patterns, the brief offers insights to policy makers and leaders where to invest for long-term improvement and targeting support where it is needed most.

To describe the impact of the COVID-19 pandemic on students, researchers have translated test scores into months of learning to claim how many months/years students are behind in school. Despite its perceived accessibility, there are major downsides to this translation. To inform future uses by researchers and media, we discuss in this brief how to calculate this metric as well as its trade-offs.

The purpose of this technical appendix is to share more detailed results and to describe more fully the sample and methods used in the research included in the brief, Learning during COVID-19: An update on student achievement and growth at the start of the 2021-22 school year. We investigated two research questions:

1. How does student achievement in fall 2021 compare to pre-pandemic levels (namely fall 2019)?
2. How did academic gains between fall 2019 and fall 2021 compare to normative growth expectations?

To what extent has the COVID-19 pandemic affected student achievement and growth in reading and math, and which students have been most affected? Using data from 6 million students in grades 3-8 who took MAP Growth assessments in reading and math, this brief examines how gains across the pandemic (fall 2019 to fall 2021) and student achievement in fall 2021 compare to pre-pandemic trends. This research provides insight to leaders working to support recovery.

The American Rescue Plan provides $122 billion for COVID recovery in schools. With more than 40 state plans approved, how are districts collecting, monitoring, reporting and learning from the unprecedented interventions? What can districts do now to design and implement data collection processes that will shape collective learning? In this webinar, you will hear how district leaders and researchers are approaching this opportunity to alter life outcomes for generations.

This study examined the stability of social-emotional learning (SEL) skills and the extent to which students’ initial level in SEL skills in 6th grade and growth in SEL skills from 6th to 8th grade are related to students’ successful transition to secondary school. Findings suggest that understanding how a student develops social-emotionally can improve identification of students not on track to succeed in high school.
