About TIMSS 2023 Banner

In 2023, IEA and the TIMSS & PIRLS International Study Center will conduct the eighth cycle of TIMSS (Trends in International Mathematics and Science Study) at the fourth and eighth grades, providing nearly 30 years of trend data on student achievement in mathematics and science. TIMSS 2023 will complete TIMSS’ transition to digital assessment, which began with TIMSS 2019, reflecting the widespread use of technology in schools and society. The TIMSS 2023 assessments will include new and engaging item formats and interactive features and scenario-based Problem Solving and Inquiry tasks (PSIs) that motivate students and capitalize on the digital environment.

Benefits of TIMSS 2023

  • Capitalizing on the Digital Environment to Better Measure Achievement

    The TIMSS 2023 mathematics and science assessments are based on comprehensive frameworks developed collaboratively with the participating countries. The digital format of the TIMSS 2023 assessments will stimulate student interest and motivation in the assessment and in turn, provide better information about what students know and can do. Moreover, a digital format also enables TIMSS to assess areas of the frameworks that are difficult to assess with a paper-and-pencil format. For example, in TIMSS PSIs, students integrate and apply process skills and content knowledge to solve mathematics problems or conduct virtual experiments and investigations.

  • Understanding Contexts for Learning

    TIMSS asks students, their parents or caregivers, their teachers, and their school principals to complete questionnaires about their home and school experiences and instructional contexts for learning mathematics and science. When examined in relation to student achievement, contextual data provide important insights into home and school factors that are associated with student achievement and can suggest avenues for educational improvement. The context questionnaire data complement the TIMSS Encyclopedia, which includes chapters, authored by country representatives, which describe countries’ education systems and mathematics and science curricula.

  • Collecting Process Data to Provide Insights into Student Approaches

    TIMSS 2023 will capture student response data and event log data as a comprehensive sequence of student interactions with the assessment interface, items, and active objects, providing a full history of how each student navigated through the assessment. The rich process data collected will allow for understanding student engagement with the assessment and can reveal which student approaches are successful or unsuccessful, providing information to help improve mathematics and science instruction.

  • Targeting Assessments to Student Populations

    The TIMSS 2023 assessments are based on a group-adaptive design, which will provide a better match between the difficulty of the assessment and student achievement and, in turn, provide better measurement at all achievement levels.
