Trends in International Mathematics and Science Study, 2011

The Trends in International Mathematics and Science Study, 2011 (TIMSS 2011) is a study that is part of the Trends in International Mathematics and Science Study (TIMSS) program; program data are available since 1999 at https://nces.ed.gov/pubsearch/getpubcats.asp?sid=073. TIMSS 2011 (https://nces.ed.gov/timss/) is a cross-sectional study that provides international comparative information of the mathematics and science literacy of fourth- and eighth-grade students and examines factors that may be associated with the acquisition of math and science literacy in students. The study was conducted using direct assessments of students and questionnaires for students, teachers, and school administrators. Fourth- and eighth-graders in the 2010–11 school year were sampled. The study's response rate was 94 percent. Key statistics produced from TIMSS 2011 are mathematics and science achievement scores of U.S. fourth- and eighth- grade students compared to that of students in other countries.
