Learning-adjusted years of school are calculated by multiplying the estimates of expected years of school by the ratio of most recent harmonized test scores to 625. Every country, region and year the World Bank publishes for indicator HD.HCI.LAYS.FE (Human Capital Index), delivered as a tidy table — country, ISO code, year and value — ready for analysis in Excel, R, Python or the Intigal AI workspace.
