Overview

The Trends in International Mathematics and Science Study (TIMSS) provides reliable and timely data on the mathematics and science achievement of U.S. 4th- and 8th-grade students compared to that of students in other countries. TIMSS data have been collected in 1995, 1999, 2003, 2007, and 2011. The next data collection is in 2015.

The TIMSS International Data Explorer (IDE) is now available for users to create their own tables and charts, and perform statistical tests with data from all years of TIMSS. The TIMSS IDE is modeled after the NAEP Data Explorer and functions the same way. The TIMSS IDE can be accessed here.

In 2011, more than 60 countries and other education systems, including the United States, participated in TIMSS. More than 20,000 students in more than 1,000 schools across the United States took the assessment in spring 2011, joining almost 500,000 other students around the world who took part in TIMSS. Because the Progress in International Reading Literacy Study (PIRLS) was also administered at grade four in spring 2011, TIMSS and PIRLS in the United States were administered in the same schools to the extent feasible. Students took either TIMSS or PIRLS on the day of the assessments.

In addition, to address the interest in states benchmarking to international standards, NCES is initiating a new effort to link the states scores from the national assessment—NAEP-- to TIMSS. The 2011 NAEP-TIMSS Linking Study is designed to provide all states with estimates that compare their own students’ performance against international benchmarks.
