Trends in International Mathematics and Science Study (TIMSS)
The Trends in International Mathematics and Science Study (TIMSS) is an independent worldwide research study, taking place every four years. TIMSS assesses the knowledge and skills of pupils aged 9-10 and 13-14 in over 60 countries and provides data about trends in mathematics and science achievement over time.
Findings from the study provide high-quality, internationally comparative data to inform education policy in Northern Ireland and across the world. TIMSS can be used to improve teaching and learning in mathematics and science and to provide valuable insights into background factors such as pupils’ attitudes, school resources, teaching practices and qualifications and how they relate to pupil achievement.
TIMSS has been developed by the International Association for the Evaluation of Educational Achievement (IEA). TIMSS 2019 will be the seventh cycle of the study, which was first conducted in 1995. This 2019 study updates the picture of performance from 2015.
