Hidden Dropout: Secondary Education (Unseen) Failure in Pandemic Times
研究估计了新冠疫情对隐性辍学的影响，即学生未达到高中毕业所需最低技能水平的情况，发现隐性辍学率上升了8.6个百分点，对成绩差、家庭贫困、情绪受扰及教育期望低的学生影响更大。
We estimate the effects of the COVID-19 pandemic on hidden drop-out, a new measure indicating failure in achieving the minimum level of skills considered to be adequate for a student getting the high school diploma. We exploit the exogenous variation induced by the pandemic by comparing two cohorts of students (one affected and the other unaffected), within the same school. We find that hidden drop-out increases by 8.6 percentage points; the effect is stronger for students with lower levels of prior achievement, from poorer families, but also for those emotionally disrupted during assessments, and for those disclosing lower educational aspirations.
