This is the technical appendix to the research brief, “Getting Algebra Placement Right: Expanding Opportunity and Strengthening Preparation,” which examines whether taking Algebra in 8th grade instead of 9th grade improves student outcomes.

This research brief examines whether taking Algebra in 8th grade instead of 9th grade improves student outcomes. Using a nationwide sample of MAP Growth scores for middle schoolers, NWEA researchers looked at how many students who were ready for Algebra actually enrolled, and how outcomes were affected for students who were or were not ready for the course.

This is the technical appendix to the “Struggling adolescent readers left behind: Evidence of post-COVID-19 declines and pathways forward” research brief, which highlights an urgent challenge in academic recovery: middle school reading.

Using data from the MAP Growth National Dashboard, this research brief highlights an urgent challenge in academic recovery: middle school reading. While students have shown encouraging progress in math and elementary reading since the pandemic, reading achievement among grades 6-8 remain stagnant, with the lowest-performing students falling even further behind.

This white paper examines how the 2025 update to NWEA’s MAP® Growth™ national norms changes the interpretation and use of key norm referenced metrics in school accountability contexts. We show how shifts in post COVID achievement and growth patterns and the introduction of NWEA’s enhanced item selection algorithm (EISA), call for careful review of commonly used metrics.

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.
