Trends in International Mathematics and Science Study 2007 (TIMSS 2007)

Research Question

TIMSS 2007 is an international educational large scale assessment. The study was designed to assess the academic skills and abilities of grade 4 mathematics and science students. In addition to data on students' achievement, the results of background questionnaires given to students, teachers and principals were considered, thus enabling researchers to investigate links between mathematics and science achievement on the one hand and class and school characteristics on the other.

Test Language


Test Period


Test Area and International Link

International survey and national supplementary study with all German Länder

Target Persons

Students from grades 4 at general education schools (including special education schools)

Context Persons

Mathematics and Science teachers of the selected students and the principals of the selected schools

Population / Sample

The sampling is based on a two-step stratified cluster design. The population of all schools was grouped by the desired categories („stratification”). Afterwards, the classes were sampled within the selected schools.

The TIMSS-2007 student sample in Germany contains 5,646 students. From this group, 5,200 students from 246 schools actually participated in TIMSS.

Sample Size

n= circa 5,200 target persons

Survey Procedure and Instruments

Competence tests in mathematics and natural sciences and background questionnaires for students, teachers and school principals

A key feature of TIMSS is that the achievement tests are adapted to the mathematics and science curricula in each participating country, with experts completing questionnaires on the intended curriculum for each individual country. The intended curriculum can then be compared to the implemented curriculum, the assessment of which was based on principals’ and teacher questionnaires. In a subsequent step, students were given achievement tests and questionnaires with regard to their classroom experiences, thereby providing information on the attained curriculum. This approach enables researchers to make more precise statements on the influence of the school environment and other contextual factors on students' learning progress.
