Trends in International Mathematics and Science Study (TIMSS)

The Trends in International Mathematics and Science Study (TIMSS) is an international assessment conducted under the auspices of the International Association for the Evaluation of Educational Achievement (IEA) and assesses the mathematics and science knowledge of students in Grades 4 and 8. TIMSS was first administered in 1995 and has been conducted every four years since.

More than 60 countries participated in TIMSS 2019. Five Canadian provinces participated: Alberta, Manitoba, and Newfoundland and Labrador in Grade 4 (as oversampling participants) and Ontario and Quebec in Grade 4 and Grade 8/Secondary II (as benchmarking participants). Canada-wide participation was coordinated by the CMEC.

Ontario has participated in the study since its inception. Previous administrations were conducted in 1995, 1999, 2003, 2007, 2011 and 2019.

The next administration will be held in 2023. A field test will be administered between March 14 and April 14, 2022, to Grade 4 students only to prepare for the administration in 2023.
