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." The goal of this brief is to summarize student achievement…

This brief is a continuation of NWEA's ongoing research agenda focused on understanding how the COVID-19 pandemic has affected student reading and math outcomes. This report builds on previous findings to examine students' academic progress at the start of the third school year impacted by the pandemic. The goal of this brief is to summarize…

We examined to what extent subgroups of students identified with learning disabilities (LDs; N = 630) in the Early Childhood Longitudinal Study, Kindergarten Class of 1998 to 1999 (ECLS-K): 1998 national longitudinal study displayed heterogeneity in longitudinal profiles of reading and mathematics achievement from first to eighth grades.…

This brief provides a policy perspective into the recent NWEA research on how COVID-19 has affected student learning. It builds on previous research showing achievement levels stalling over the 2022-23 school year from the previous year. This analysis on student learning from grades 3-8 shows that academic recovery has stalled for older learners…

In this paper, we use NWEA MAP test data to examine variation in students' achievement and growth during the pandemic across multiple dimensions.
