The COVID-19 pandemic resulted in significant disruption in schooling worldwide. Global test score data is used to estimate learning losses by modeling the effect of school closures on achievement by predicting the deviation of the most recent results from a linear trend using data from all rounds of PISA. Mathematics scores declined an average of 14 percent of a standard deviation, roughly equal to seven months of learning. Losses are greater for students in schools that faced relatively longer closures, for boys, immigrants, and disadvantaged students. Educational losses may translate into significant national income losses over time.
新冠疫情导致全球范围内的学校教育受到严重干扰。全球测试分数数据被用于估计学习损失，其方法是通过使用国际学生评估项目（PISA）各轮次的数据，对学校关闭对成绩的影响进行建模，预测最近结果与线性趋势的偏差。数学成绩平均下降了一个标准差的14%，大致相当于七个月的学习量。对于面临相对较长关闭时间的学校的学生、男生、移民学生和弱势学生来说，学习损失更大。随着时间的推移，教育损失可能会转化为巨大的国民收入损失。
