Next week, the TIMSS 2023 Longitudinal Study, a landmark extension of the Trends in International Mathematics and Science Study (TIMSS) will be released. For the first time, TIMSS has followed the same students over time, testing the 2023 cohort again in 2024. This design unlocks something educators and policymakers rarely get at scale: direct evidence of learning growth, not just achievement snapshots.
Join us on Wednesday, December 10 at 11:00 AM ET for conversation about what the study reveals, why it matters, and how U.S. leaders can use these insights to guide policy, instruction, and long-term system design. We’ll highlight which countries saw notable gains, what may have contributed to their progress, and what the findings suggest about curriculum, instruction, and teacher support. We’ll also explore what this could mean for strengthening math and science learning here at home.
The conversation is designed for educators, school and district leaders, state policymakers, researchers, and anyone looking for a clear, global picture of how students are learning today.
