The [[International Association for the Evaluation of Educational Achievement]] (IEA)'s '''Trends in International Mathematics and Science Study''' ('''TIMSS''')<ref>{{Cite web |title=TIMSS and PIRLS Home |url=https://timssandpirls.bc.edu/ |url-status=live |archive-url=https://web.archive.org/web/20240206005353/http://timssandpirls.bc.edu/ |archive-date=Feb 6, 2024 |website=timssandpirls.bc.edu}}</ref> is a series of international assessments of the mathematics and science knowledge of students around the world. The participating students come from a diverse set of educational systems (countries or regional jurisdictions of countries) in terms of economic development, geographical location, and population size. In each of the participating educational systems, a minimum of 4,000 to 5,000 students is evaluated. Contextual data about the conditions in which participating students learn mathematics and science are collected from the students and their teachers, their principals, and their parents via questionnaires.<ref name="About TIMSS 2023">{{cite web|title= About TIMSS 2023|url=https://timss2023.org/|publisher= TIMSS International Study Center|access-date=2 June 2025}}</ref>

TIMSS is one of the studies established by IEA aimed at allowing educational systems worldwide to compare students' educational achievement and learn from the experiences of others in designing effective education policy. This assessment was first conducted in 1995, and has been administered every four years thereafter. Therefore, some of the participating educational systems have trend data across assessments from 1995 to 2023.<ref name="TIMSS & PIRLS Home">{{cite web|title=TIMSS & PIRLS International Study Center|url=http://timssandpirls.bc.edu/|access-date=15 December 2016}}</ref> TIMSS assesses 4th and 8th grade students, while TIMSS Advanced assesses students in the final year of secondary school in advanced mathematics and physics.

==Definition of terms==

"Eighth grade" in the [[United States]] is approximately 13–14 years of age and equivalent to:

* Year 9 (Y9) in England and Wales
* 2nd Year (S2) in Scotland
* 2nd Year in the Republic of Ireland
* 1st Year in South Africa
* Form 2 in Hong Kong
* 4ème in France
* Year 9 in New Zealand
* Form 2 in Malaysia

"Fourth grade" in the [[United States]] is approximately equivalent to 9–10 years of age and equivalent to:

* Year 5 (Y5) in England and Wales
* Primary 6 (P6) in Scotland
* Group 6 in the Netherlands
* CM1 in France
* Fourth Class in the Republic of Ireland
* Standard 3 or Year 5 in New Zealand

==History==

A precursor to TIMSS was the First International Mathematics Study (FIMS) performed in 1964 in 11 countries for students aged 13 and in the final year of secondary education (FS) under the auspices of the  [[International Association for the Evaluation of Educational Achievement]] (IEA). This was followed in 1970–1971 by the First International Science Study (FISS) for students aged 10, 14, and FS. Fourteen countries tested 10-year-olds; 16 countries tested the older two groups. These were replicated between 1980 and 1984.<ref>Hanushek and Woessmann (2015, Table 2.1, p. 18).</ref>

These early studies were revised and combined by the IEA to create TIMSS, which was first administered in 1995. It was the largest international student assessment study of its time and evaluated students in five grades. In the second cycle (1999) only eighth-grade students were tested. In the next cycles (2003, 2007, 2011, and 2015) both 4th and 8th grade students were assessed. The 2011 cycle was performed in the same year as the IEA's [[Progress in International Reading Literacy Study]] (PIRLS), offering a comprehensive assessment of mathematics, science and reading for the countries participating in both studies. The sixth cycle was conducted in 2015, and the results were released in 2016;<ref name="TIMSS 2015 and TIMSS Advanced 2015 International Results">{{cite web|title= TIMSS 2015 and TIMSS Advanced 2015 International Results|url=http://timssandpirls.bc.edu/timss2015/international-results/|publisher= TIMSS International Study Center|access-date=15 December 2016}}</ref> the data set was published in February 2017. TIMSS 2015 included data collected from parents for the first time.<ref name="www.iea.nl">{{cite web|url=http://timssandpirls.bc.edu/timss2011/countries.html|title=TIMSS 2011 Participating Countries|access-date=21 Nov 2016}}</ref> TIMSS Advanced, previously conducted in 1995 and 2008, was also conducted in 2015, and assessed final-year secondary students' achievement in advanced mathematics and physics. Policy-relevant data about curriculum emphasis, technology use, and teacher preparation and training accompanies the TIMSS Advanced results.

The seventh cycle of TIMSS was conducted in 2019 and marked the beginning of the transition to a digital assessment format, with the digital assessment administered to half of participating countries, and the paper assessment administered to the remaining half. 64 countries and 8 benchmarking systems participating in TIMSS 2019. Results were released in December 2020.<ref name="TIMSS 2019 International Results in Mathematics and Science">{{cite web|url=https://timssandpirls.bc.edu/timss2019/|title=TIMSS 2019 International Results in Mathematics and Science|access-date=3 May 2021}}</ref>

==Method, data and documentation==
Along with the overall students' achievement data, TIMSS comprehensive assessments include data on student performance in various mathematics and science domains (algebra, geometry, biology, chemistry, etc.) and on performance in the problem solving challenges in each of these contexts. In addition, TIMSS provides contextual data on crucial curricular, instructional, and resource-related factors that can impact the teaching and learning process. These data are gathered using student, teacher, school, and curriculum (national) questionnaires filled out by students, teachers, school principals and National Research Coordinators, respectively.

According to the TIMSS 2019 Assessment Frameworks, "The TIMSS mathematics and science achievement scales were created with the first TIMSS assessment in 1995, separately for each subject and each grade. The scale units were established so that 100 points on the scale was equivalent to one standard deviation of the distribution of achievement across all of the countries that participated in TIMSS 1995, and the scale midpoint of 500 was located at the mean of this international achievement distribution. The TIMSS achievement scales were first used for reporting TIMSS results with TIMSS 1995, and all results from subsequent TIMSS assessments have been reported on the same scale metrics, making it possible to measure growth or decline in countries' achievement distributions from assessment to assessment."<ref>{{cite web|title=TIMSS 2019 Assessment Frameworks|url=http://timssandpirls.bc.edu/timss2019/frameworks/framework-chapters/assessment-design/reporting-student-achievement/|publisher=TIMSS & PIRLS International Study Center|access-date=3 May 2021}}</ref>

Because TIMSS is administered in four-year cycles, it enables participating counties to use the results between the fourth and eighth grades to track the changes in achievement and certain background factors from an earlier study. For example, results of the fourth grade in TIMSS 1995 can be compared with the results of the eighth grade in TIMSS 1999, as fourth graders had become eighth graders in the next cycle of study.<ref name="U.S. Department of Education">{{cite web|title=Pursuing Excellence: Comparisons of International Eighth-Grade Mathematics and Science Achievement from a U.S. Perspective, 1995 and 1999|url=http://nces.ed.gov/pubs2001/2001028.pdf|publisher=U.S. Department of Education|access-date=4 May 2013|page=2|date=December 2000}}</ref>

The IEA has developed an application for working with data from TIMSS and other IEA large-scale assessments called the IEA International Database (IDB) Analyzer.<ref>{{Cite web|url=https://www.iea.nl/data-tools/tools|title=Tools &#124; IEA.nl|website=www.iea.nl}}</ref> This application allows researchers to combine data files and facilitates some types of statistical analysis (such as computing [[mean]]s, [[percentages]], [[percentiles]], [[correlations]], and estimating single level multiple [[linear regression]]). The application takes into account the complex sample structure of the databases when calculating the statistics and their standard errors. It also allows researchers to estimate achievement scores and their standard errors.

=== TIMSS 2019 ===

TIMSS 2019 marked the transition to a digital assessment format, allowing for new and innovative item types. In the digital assessment, students solved problems by interacting with shapes and patterns, arranging items on the screen, dragging and dropping items, and drawing. The digital version of TIMSS 2019 also introduced Problem Solving and Inquiry tasks that simulated real-world and laboratory situations and called for students to integrate and apply process skills and content knowledge. Half of the participating countries took the paper version of TIMSS and half of the participating countries took the digital version of TIMSS.

== Additional initiatives ==
The TIMSS 1999 Video Study<ref>{{cite web |url=http://www.timssvideo.com/ |title = TIMSSVIDEO}}</ref> was a study of eighth-grade mathematics and science teaching in seven countries. The study involved videotaping and analyzing teaching practices in more than one thousand classrooms. In conjunction with the IEA, the study was conducted by the US National Center for Education Statistics, and the US Department of Education under a contract with LessonLab, Inc. of Los Angeles, California.

==Cooperative partners==
TIMSS depends on the collaboration of a large number of individuals and organizations around the world including the [http://timssandpirls.bc.edu/ TIMSS & PIRLS International Study Center at Boston College], [http://www.iea.nl/ IEA's offices in Amsterdam and Hamburg], [[Statistics Canada]], and [[Educational Testing Service]] (ETS). In the United States, TIMSS is conducted by the [[National Center for Education Statistics]] of the US Department of Education. Data for US students is further tracked for ethnic and racial groups. TIMSS is mainly funded by the participating countries. Also, the US National Center for Education Statistics of the US Department of Education and the World Bank provide major support funding for the assessments.<ref name="www.iea.nl"/>

==TIMSS and other international math and science studies == 
Hanushek and [[Ludger Woessmann|Woessmann]]<ref>Hanushek and Woessman (2015, esp. Table 2.1 and Appendix 2A, pp. 18, 29-37)</ref> developed a methodology to rescale 14 different international comparisons of math and/or science achievement to make them comparable.  This includes the FIMS, FISS, and PISA, mentioned above, with TIMSS.

This methodology is disputed amongst experts. Quantitative methods used in educational and psychological measurement disagree with the approach as it is basically only a linear scale transformation that cannot ensure or examine whether PISA and TIMSS scores are based on the same or at least comparable measurement constructs: The numerical values used to measure shoe size and intelligence can be transformed so that both have the same arithmetic mean and standard deviation, but they still represent two very different characteristics. The equivalency of what is being measured needs to be established in linking studies that utilize well-designed joint data collections such as the TIMSS NAEP link,<ref>{{cite web | url=https://nces.ed.gov/nationsreportcard/studies/naep_timss/ | title=Methodology Studies - Linking NAEP and TIMSS Study &#124; NAEP }}</ref> or IEA's Rosetta Stone.<ref>{{cite web | url=https://www.iea.nl/news-events/news/iea-rosetta-stone-project-moves-ahead | title=IEA Rosetta Stone project moves ahead &#124; IEA.nl }}</ref>

Wu (2003, 2010)<ref>Wu, M. (2010), "Comparing the Similarities and Differences of PISA 2003 and TIMSS", OECD Education Working Papers, No. 32, OECD Publishing, Paris, https://doi.org/10.1787/5km4psnm13nx-en.</ref> has shown that TIMSS and PISA do not produce exchangeable scores. One reason may be reading load even for mathematics and science items. TIMSS questions focus on the mathematics curricula taught around the world as seen in TIMSS example items,<ref>{{cite web|url=https://nces.ed.gov/timss/pdf/TIMSS2011_G8_Math.pdf|title=TIMSS USA Grade 8 Released Mathematics Items|publisher=International Association for the Evaluation of Educational Achievement|year=2013|access-date=2024-06-28}}</ref> while PISA attempts to assess mathematics embedded in descriptions of situations encountered outside of the classroom, see PISA examples.<ref>{{cite web|url=https://www.oecd.org/pisa/38709418.pdf|title=PISA Released Items – Mathematics|publisher=OECD|date=December 2006|access-date=2024-06-28}}</ref>
