    <abstract>The Trends in International Mathematics and Science Study (TIMSS) is an international assessment of the mathematics and science knowledge of 9–10 and 13–14 year old (Year 5 and Year 9 or fourth grade and eighth grade) students around the world. TIMSS was developed by the International Association for the Evaluation of Educational Achievement (IEA) to allow participating nations to compare students' educational achievement across borders. TIMSS was first administered in 1995, and every 4 years thereafter. In 1995, forty-one nations participated in the study. TIMSS consists of an assessment of mathematics and science, as well as student, teacher, and school questionnaires. The current assessment includes those topics in mathematics and science that students are likely to have been exposed to up to and including grade 4 and grade 8.</abstract>

    <notes>TIMSS 1999 was the second assessment in the series of IEA studies to measure trends in students' mathematics and science achievement. TIMSS 1999 was conducted by the TIMSS &amp; PIRLS International Study Center at Boston College and included 38 countries. The 1999 assessment 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.

The TIMSS 1999 Benchmarking Study included 13 states and 14 districts or consortia of districts from all across the United States. The TIMSS 1999 assessments were administered to representative samples of eighth-grade students in the districts and states in the spring of 1999, at the same time and following the same guidelines as those established for the 38 participating countries. In addition to testing achievement in mathematics and science, the TIMSS 1999 Benchmarking Study collected extensive information from students, teachers, and school principals about mathematics and science curricula, instruction, home contexts, and school characteristics and policies.</notes>

      <collSitu>IN ADDITION TO MEASURING TRENDS in mathematics and science achievement through analysis of curricula and text-books, TIMSS 1999 collected extensive information about the teaching and learning of mathematics and science around the world. Through a series of questionnaires, TIMSS gathered information about curriculum, instructional practices, policies, and student background and attitudes. Many of the questions also were asked in 1995, providing trends for countries that participated in both assessments.</collSitu>
