Adjusted Secondary Test Scores for International Comparison 1965-2010

A standardized test score for secondary education, adjusted for comparability over time, across subjects, and across international and regional assessments. The dataset provides adjusted scores approximated to 5-year intervals from 1965 to 2010. It was created by Education Statistics using data from assessments like PISA, TIMSS, and the U.S. NAEP.

Use Cases

• Analyze trends in adjusted secondary test scores over 5-year intervals from 1965 to 2010.
• Compare standardized secondary education performance across different countries using the adjusted score metric.
• Investigate the relationship between participation in regional versus international assessments and the derived adjusted scores.

Strengths

• Scores are standardized for comparability across time, subjects, and different international tests.
• Data covers a 45-year time range from 1965 to 2010.

Limitations

• The specific number of countries, rows, and columns is unknown.
• Data points are approximated to the nearest 5-year interval, which may obscure annual fluctuations.
• The methodology for creating adjusted scores for countries only in regional assessments relies on a proxy ratio from 'doubloon' countries.

Provenance

Source

Education Statistics (likely within The World Bank Group).

Collection Method

Calculated by creating ratios between U.S. scores on international tests (e.g., PISA, TIMSS) and the U.S. NAEP, then applying these to raw international and regional assessment scores.

Time Range

1965 to 2010.

Geography

International coverage, including countries participating in international and regional assessments.
