TIMSS (Trends in International Mathematics and Science Study) is a large-scale assessment designed to inform educational policy and practice by providing an international perspective on teaching and learning in mathematics and science. 

TIMSS conducts comprehensive state-of the-art assessments of mathematics and science for students in Year 4 and Year 8, supported with extensive data about country, school, and classroom learning environments.  First conducted in 1995, TIMSS reports every four years on the achievement of Year 4 and Year 8 students. Australia has participated in all six cycles.

Although the current cycle is referred to as TIMSS 2019, in Australia the assessment takes place in 2018, because of differences in the timing of the school year in the northern and southern hemispheres.

Who’s involved in TIMSS?

More than 60 countries from all over the world participated in TIMSS 2015.

In Australia, more than 570 schools and more than 16 000 students at Year 4 and Year 8 were involved.

TIMSS is a project of the International Association for the Evaluation of Educational Achievement (IEA) and is directed by the TIMSS International Study Center at Boston College in collaboration with a worldwide network of organisations and representatives from the participating countries. ACER is responsible for undertaking the data collection in Australian schools.
