How does student educational performance change over time? What are the experiences and opportunities related to differences in students’ educational performance? How does student educational performance vary across the states? How does the U.S. compare in terms of students’ educational performance internationally? The key tool to uncover the answers to these kinds of questions are with educational assessment studies. Findings from educational assessment studies help inform policymakers and guide educational improvements for children, students, and adults worldwide. Westat is at the forefront of these efforts, fielding large-scale national and international educational assessment studies to track these issues and important trends, with the aim to support student learning both within the U.S. and across the globe.
