TIMSS 2015 Release Marks 20 Years of Trends

International Mathematics Achievement at the Fourth Grade. The gap between the East Asian countries — Singapore, Hong Kong SAR, Korea, Chinese Taipei, and Japan — and the next highest countries was 23 points with the highest scorer receiving a total of 618 points.

IEA's TIMSS & PIRLS International Study Center at Boston College released the results of TIMSS 2015 and TIMSS Advanced 2015 on November 29, 2016. The release marked 20 years of trends for TIMSS, which was first conducted in 1995. By reaching this milestone, TIMSS earns the distinction of establishing the longest trend line of any international education assessment. Approximately 600,000 students worldwide participated in TIMSS and TIMSS Advanced 2015, which provide country comparisons in mathematics and science achievement, and comprehensive data on the home and school contexts for teaching and learning those subjects. For more information, read a roundup of results from Boston College.
