Third International Mathematics and Science Study (TIMSS) Archive


TIMSS 1999 was the second assessment in the series of studies by the International Association for the Evaluation of Educational Achievement (IEA) to measure trends in students' mathematics and science achievement.

TIMSS 1999 was conducted by the International Study Center at Boston College and included 38 countries. It measured the mathematics and science achievement of eighth-grade students (ages 13 and 14 years) and collected extensive information from students, teachers, and school principals about mathematics and science curricula, instruction, home contexts, and school characteristics and policies.

Of the 38 participating countries, 26 also participated in the 1995 TIMSS assessment, which enabled these countries to measure trends in their children's mathematics and science achievement and in schools and home contexts for learning.
