Welcome to the homepage for TIMSS (Trends in International Mathematics and Science Study) in Ireland.

TIMSS is an international comparative study of mathematics and science achievement at both primary (Fourth class) and post-primary (Second Year) levels.  It takes place every four years and was first conducted in 1995. Ireland took part at both primary and post-primary level in the 2015 assessment.‎

TIMSS is a project of the International Association for the Evaluation of Educational Achievement (IEA) – an independent, international cooperative of national research institutions and governmental research agencies.  The study is managed by a group of agencies, led by the IEA International Study Center located in Boston College, United States.

In Ireland, the Educational Research Centre manages the implementation of TIMSS on behalf of the Department of Education and Skills.

Initial results from TIMSS 2015 were published on November 29th, 2016.  The Irish national report on Fourth Class and Second Year students’ performance on the mathematics and science assessments can be downloaded here. More detailed contextual analyses and findings can be downloaded here.

Work is ongoing on Ireland’s participation, at both Fourth Class and Second Year, in TIMSS 2019.  Approximately 30-40 schools at each grade level participated in a field trial in 2018. Approximately 150 schools at each level will be asked to participate in the main study in 2019.
