The COVID-19-induced school closures lasted 26 weeks in Poland, one of Europe's longest periods of shutdown. Comparison of the learning outcomes with pre- and post-COVID-19 samples shows that the learning loss was equal to more than one year of study. Assuming a 45-year working life of the total affected population, the economic loss in future student earnings may amount to 7.2 percent of Poland’s gross domestic product.enCC BY 3.0 IGOCOVID-19 LEARNING LOSSSCHOOL CLOSURESCOVID-19 IMPACT ON EDUCATIONECONOMIC IMPACT OF LEARNING LOSSPRIMARY EDUCATIONSECONDARY EDUCATIONWorking PaperWorld Bank10.1596/1813-9450-10253
