TIMSS (the Trends in International Mathematics and Science Study) is an international comparison of pupil performances in mathematics and science. Fourth-grade Danish pupils are involved in TIMSS.  Denmark has previously taken part in TIMSS in 1995, 2007, 2011 and 2015. The next TIMSS study is taking place in 2019.

The TIMSS studies, which are carried out once every four years, are planned and managed by the International Association for the Evaluation of Educational Achievement (IEA).

The IEA is an organisation of research institutions, and the Danish School of Education at Aarhus University is a member.

TIMSS is carried out in more than 60 countries and Denmark has participated five times: in 1995, 2007, 2011, 2015 and 2019. The study is an important element in providing knowledge and insight into how Danish students' skills in mathematics and nature/technology develop compared with students in other countries.

The advantage of the study is that it is supported at ministerial level and therefore has the potential to make changes or maintain the active initiatives that affect the students' learning outcomes and the quality of education in primary and lower secondary school.
