The TIMSS & PIRLS International Study Center at Boston College is thrilled to announce the results of the “TIMSS 2023 Longitudinal Study”, displaying student growth in both math and science.
The IEA’s TIMSS & PIRLS International Study Center runs large-scale international assessments of student achievement in math, science, and reading across more than 60 countries. This latest study supports the idea that cognitive development slows down during adolescence, compared to the faster growth seen in early childhood.
Contextual questionnaires were given to students, parents, teachers, and principals to identify factors contributing to students’ academic success. By using updated questionnaires, the study results reveal the unique ways in which home, classroom, and school environments influence learning gains and achievement improvements.

“For decades, TIMSS has shown where students are in their learning. Now, for the first time, we can open the black box and see how much they learn, tracking their growth directly,” says Matthias von Davier, Executive Director of the TIMSS & PIRLS International Study Center at Boston College.
“This isn't just a snapshot; it's a movie of student progress. We see that all systems produce growth, but the pace varies. More importantly, we can now identify the specific supports—from a resource-rich home to asafe and supportive school—that help students thrive.”
