Trends in International Mathematics and Science Study – TIMSS – provides invaluable insights into the state and developmental dynamics of the education system. It therefore represents a unique opportunity not only for shaping education policy, but also for strengthening schools themselves.

To this end, it is essential that schools become active users of the evidence generated through international assessments, evidence that is directly aimed at improving teaching and learning processes. In pursuit of this objective, reports from international assessments, including TIMSS, are presented in a new format.

Experience has shown that the traditional reporting model—consolidating research findings into a single, lengthy, and complex document—tends to limit the effective use of results.

The TIMSS report presented here marks the first step in introducing a new format for disseminating the results of international assessments. It reflects an effort to employ international data as a guide for evidence-based change, not only at the level of policy but also at the level of the school.

The national report has been titled “Lessons from TIMSS 2023.” Each series within this report will address a specific theme and will be published under an appropriate thematic heading.
