1. COVID-19 and school closures
abstractTo reduce the spread of COVID-19, schools closed to an unprecedented degree in the spring of 2020. To varying extent, students have moved between in-person and remote learning up until the spring of 2021. This chapter surveys the literature on the implications of school closures of primary to upper-secondary schools for virus transmission, student learning, and mental health among children and adolescents in high-income countries. Subject to severe methodological challenges, most studies indicate that the initial school closures at least to some extent contributed to a reduction of virus transmission. However, several studies find that schools could reopen safely, especially when substantial within-school preventive measures were implemented and the general level of transmission was moderate. Student age also matters and keeping schools open for younger students contributes less to overall virus transmission. Most studies find that students learned less and that learning inequalities widened when school closed. These patterns are particularly pronounced for younger students who face more challenges adjusting to remote instruction. Essentially nothing can be said concerning the implications for vocational training. High-quality evidence on the impact on mental health is scarce and the results are mixed, but there are some indications that older students coped better with school closures also in this regard. On balance, closing schools for younger students is less well-motivated than for older students.

abstractIn Sweden, a trust-based system of school performance evaluation meets a market-oriented school system with liberal entry conditions for voucher-funded private providers. National standardized tests are graded at the local school and what ultimately matters to students are teacher-set grades. This paper finds that privately run free schools systematically set higher grades than public schools when controlling for their achievement on national tests. The differences between municipal and free schools are larger when more reliable tests are used to account for achievement. Differences in grading standards between providers are substantial and most of the performance advantage in teacher-set grades that free schools enjoy can be attributed to more generous grading. The results also indicate that different private providers do not necessarily respond symmetrically when faced with similar market conditions and act under the same regulatory regime.

9. The impact of upper-secondary voucher school attendance on student achievement : Swedish evidence using external and internal evaluations
abstractSweden has a school voucher system with universal coverage and full acceptance of corporate providers. Using a value added approach, we find that students at upper-secondary voucher schools on average score 0.06 standard deviations lower on externally graded standardized tests in first year core courses. The negative impact is larger among lower achieving students (but not among immigrant students), the same students who are most prone to attend voucher schools. For high achieving students, the voucher school impact is around zero. Comparing internal and external evaluations of the same standardized tests, we find that voucher schools are 0.14 standard deviations more generous than municipal schools in their internal test grading. The greater leniency in test grading is relatively uniform across different groups, but more pronounced among students at academic than vocational programs. The findings are consistent with voucher schools responding more to differences in educational preferences than municipal schools
