Schedule
Objectives
  • Monitor system-level trends in student achievement in mathematics and science at Grades 4 and 8 in a global context.
  • Inform education policy and monitor the impact of new or revised policies.
  • Identify any underperforming areas and stimulate curricular reform.
  • (With the digital format) Assess areas of the frameworks that are difficult to assess with a paper-and-pencil format.
  • Understand student engagement and approaches with the assessment by gathering process data and provide important information to help improve mathematics and science instruction.
  • Observe the performance of the fourth-grade cohort from the previous cycle at the eighth grade in the next cycle.
  • Gather important information about home and school contexts for teaching and learning in relation to students’ achievement in mathematics and science.
  • Compare education systems worldwide in terms of their organization, curricula, instructional resources, and practices related to their students’ achievement, thus allowing them to learn from the experiences of others in designing effective education policy
  • Enable countries to gain a more holistic understanding of educational outcomes by participating in both TIMSS and IEA’s International Computer and Information Literacy Study (ICILS) at the same time.

Benchmarking participants (i.e., regional jurisdictions): Ontario (Canada), Quebec (Canada), Kurdistan (Region of Iraq), Abu Dhabi (UAE), Dubai (UAE), Sharjah, UAE

 

Target population and sample (summary)

Target population (students)

All students enrolled in the grades representing 4 and 8 years of formal schooling respectively, counting from the first year of ISCED Level 1.

 

Sample (students)

  • Per country and target grade: at least 150 schools, one or more classes per grade, approximately 4,000 students total
  • Across all countries and both grades, more than 650,000 students (almost 360,000 students in fourth grade and more than 290,000 students in eighth grade)
Data collection techniques and instruments (summary)

Large-scale assessments of student achievement

  • TIMSS uses a matrix sampling approach that involves packaging the entire assessment pool of mathematics and science items at each grade level into a set of student achievement booklets or test forms (a booklet equivalent in the context of computer-based assessments).
  • TIMSS 2023 completed the transition to a fully digital assessment
    • Available in Grade 4 and Grade 8
      • Mathematics and science, Grade 4: 14 booklets
      • Mathematics and science, Grade 8: 14 booklets
    • Using a group adaptive design
  • paperTIMSS was administered in a small number of countries for whom the fully digital TIMSS may not be logistically feasible
  • For the first time, TIMSS offered a longitudinal option in which the same students that participate in TIMSS 2023 could take the same assessment one year later. This optional extension provided a more granular look at education progress over the course of one year.

 

Background questionnaires

  • Student questionnaire
  • Teacher questionnaire
  • School questionnaire
  • Early Learning Survey (also called the “home questionnaire”), grade 4 only
  • Curriculum questionnaire (completed by National Research Coordinators)

 

Descriptive encyclopedia chapters

Each country and benchmarking participant prepared a chapter describing the structure of the country’s education system, the mathematics and science curricula in the primary and secondary grades, the teacher education requirements, the types of examinations and assessments employed, policies associated with their mathematics and science curricula, school organizational approaches, and instructional practices.
