Int’l Comparative Tests

U.S. Performance on the International Comparative Tests, 1964-2025
In this section you will find charts that graphically illustrate selected country score averages from certain international comparative tests. Each chart depicts the scores in either mathematics or science of the top five scoring nations and that of the United States. The included tests are:

• FIMS: First International Mathematics Survey, pre-university students (1964)
• FISS: First International Science Survey, pre-university students (1970)
• TIMSS: Trends in International Mathematics and Science Study, 8th grade students (1995–2023)
• PISA: Programme in International Student Assessment, 15-year-old students (2000–2025)
