Private schools cater for around 1 in 5 students from pre-primary to the end of secondary education, a share that has not changed materially since 2015. They enjoy greater autonomy, suffer fewer shortages of all kinds and handled the COVID-19 pandemic better than public schools. Although their students achieved better results in PISA 2022 in many countries, this is mainly because they enrol more students from advantaged socio-economic backgrounds than their public counterparts. The main challenge in many countries today is to increase the social mix in public and private schools, which is why many efforts have been made in this direction over the past decade.
