This is the technical appendix to the research brief, “The Power of Connectedness: A Case for a Coherent Instructional System for Reading and Science Improvement,” which examines the practices and conditions of a coherent instructional system, and where and how it had the most impact.

Using a case study from a U.S. school district, this research brief examines the practices and conditions of a coherent instructional system, and where and how it had the most impact. It offers a practical model that leaders can adapt in their own schools to help strengthen instruction across classrooms.

Using data from the MAP Growth National Dashboard, this Trends Snapshot report focuses on academic growth trends post-COVID and points to a positive turn for U.S. reading after years of stagnation. This positive trend was also noted for historically underserved groups who showed the largest reading gains from 2025 to 2026.

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 white paper examines the landscape of middle school science course offerings, enrollment patterns, and assessment outcomes. The analysis of data from 2,200 schools finds that multi-disciplinary course models now dominate versus single-course offerings, though access to course types varies by race and ethnicity. In addition, students in different course models performed similarly on assessments.

This is the technical appendix to the “Unequal Access to 8th-Grade Algebra: How School Offerings and Placement Practices Limit Opportunity” research brief, which examines how access to early Algebra remains highly inequitable across the United States.
