This is the technical appendix for “Chronic absenteeism: A continued impediment to academic recovery,” research brief, which examines the relationship between chronic absenteeism and academic recovery from COVID-era disruptions to learning.

This research brief examines the relationship between chronic absenteeism and academic recovery from COVID-era disruptions to learning. Using MAP Growth data from 2,000 US school districts, NWEA researchers analyzed whether persistently high absenteeism rates were associated with slower recovery in math and reading.

The 2025 norms update addresses several critical factors: evolving U.S. student demographics, documented shifts in academic performance following the COVID-19 pandemic, and the item-selection algorithm in the newly enhanced MAP® Growth™.

NWEA research brief examining Kindergarten test scores from more than 400,000 U.S. students and noting patterns that can predict academic success or identify students at risk of falling further behind. This early identification is key for educators, enabling them to intervene and influence learning trajectories before the next critical milestone: third grade.

This early identification is key for educators, enabling them to intervene and influence learning trajectories before the next critical milestone: third grade.

This is the technical appendix to the research, “Academically diverse classrooms, deeper needs,” research brief examines the academic diversity of post-COVID classrooms, including the composition and spread of academic achievement levels. Key findings highlight the challenges facing educators as more students are off-track and further behind grade-level proficiency.
