意大利是第一个由Covid-19袭击的西方国家在2020年2月袭击，并在学年结束时致以紧张的锁定和全学校关闭。本文估计大流行和学校关闭对意大利小学生数学技能的影响。我们比较两位队列的学习成就，坐在的学生和Covid队列。For both cohorts, we match scores on the national standardised assessment in grade 2 with scores on a standardised test delivered by the researchers at the end of grade 3. The pandemic had a large negative impact on the pupils’ performance in mathematics (-0.19 standard deviations). Among children of low-educated parents, the learning loss was larger for the best-performing ones (up to -0.51 s.d.) and for girls (-0.29 s.d.).
