The Third International Mathematics and Science Study* (TIMSS) collected data on hundreds of thousands of mathematics and science students and their teachers in 1995 and again in 1999. A third round of data collection is scheduled for May 2003. Students at several grade levels were tested in mathematics and science and they also responded to a questionnaire about their background and opinions. Additional information about the teaching and learning of mathematics and science was collected from the students as well as from thousands of teachers and school principals.

Technical reports and the complete international database have been published. All of these publications are available for downloading free of charge from the TIMSS website . TIMSS data files can be downloaded in ASCII format and are accompanied by programs, codebooks and user guides that help in preparing the files for research use.

As part of its research program, Edudata is creating a research database for the TIMSS datasets. Since obtaining and converting the data files into SPSS format is a rather long and technical process, Edudata offers online access to the "TIMSS Ready-to-Use Database" which is available via the Edudata website.

The database contains files in SPSS format that researchers can download. The database is a work-in-progress and files will be added to it over time. At the outset, we are focussing on the Canadian results from TIMSS, and several files containing the Canadian data can be downloaded now.
