Description:
To what extent has the learning progress of school-aged children slowed during the COVID-19 pandemic? A pre-registered analysis of the first international assessment to be published since the pandemic is conducted to estimate the impact of COVID-19 on student reading. The effect of closures on achievement is modeled by predicting the deviation of the most recent results from a linear trend in reading achievement using data from all rounds using data from 28 countries in Europe and Central Asia. Reading scores declined by an average of 20 percent of a standard deviation, equivalent to just less than a year of schooling. Losses are significantly larger for students in schools that faced relatively longer closures. While there are no significant differences by sex, it is shown that lower-achieving students experienced much larger losses
