EDSTATS: Adjusted Primary Science Score — every country, all years (World Bank)

A test score that has been standardized over time and across various international and regional science assessments taken at the primary school level. It is calculated by creating a ratio between U.S. primary science scores on international tests (such as PISA and TIMSS) to primary science scores on the U.S. National Assessment of Educational Progress (NAEP) approximated to the nearest 5-year time step from 1965-2010. All raw primary science international scores are approximated to the nearest 5-year interval, averaged, and then multiplied by this ratio. This makes these adjusted scores comparable over time, across countries and across international tests. Primary science test scores from countries which only participate in regional assessments are included in the above transformation after being multiplied by a ratio comparing average primary science scores in a given regional test and Every country, region and year the World Bank publishes for indicator AED.PRIM.SCNC (Education Statistics), delivered as a tidy table — country, ISO code, year and value — ready for analysis in Excel, R, Python or the Intigal AI workspace.
