Adjusted primary mathematics scores standardize results from international and regional assessments like PISA and TIMSS against U.S. NAEP scores for cross-temporal and cross-national comparison. The dataset covers a 45-year period from 1965 to 2010, with scores approximated to 5-year intervals. It is produced by Education Statistics, utilizing data from multiple international assessments.
Use Cases
- Compare adjusted_primary_math_score trends across countries over the 1965-2010 period to identify global patterns in educational improvement.
- Analyze the relationship between a country's adjusted_primary_math_score and other national development indicators by joining on country code and year.
- Validate the standardization methodology by examining score ratios for 'doubloon countries' that participated in both regional and international assessments.
- Model future primary mathematics performance using time-series analysis on the 5-year interval scores.
Strengths
- Scores are adjusted for comparability across different international tests (PISA, TIMSS) and over a long time span.
- Methodology explicitly handles data from countries participating only in regional assessments via ratio transformations.
Limitations
- Data granularity is limited to 5-year intervals, obscuring annual fluctuations.
- The adjustment process relies on approximations, which may introduce measurement error.
- The most recent data point is from 2010, making the dataset over a decade old.
