Between 2015 and 2021, the school completion rate increased from 85% to 87% in primary, from 74% to 77% in lower secondary and from 54% in 2015 to 58% in upper secondary education. Even before the onset of COVID19, these rates had slowed down relative to progress in 2010–15. Looking closely at reading levels at the end of primary school, for which trend data cover 34% of the world’s children, the analysis shows that global learning levels showed no progress between 2015-2019. Furthermore, learning losses due to COVID-related school closures have been documented in 4 out of 5 of the 104 countries that have carried out such studies.
