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.

The 2015 assessment, therefore, was the sixth assessment in the series. TIMSS provides education policymakers, administrators, teachers and researchers with insights into how educational systems are functioning, as well as important information when considering education reform and improvement. In 2015, 64 jurisdictions, comprising 57 countries and seven benchmarking entities (regional jurisdictions such as provinces and states, including Ontario and Quebec) participated in TIMSS.

In Ontario, over 4500 Grade 4 students from 151 English and French schools participated in the assessment. In Grade 8, more than 4500 students from 138 English and French schools took part.

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