On average across OECD countries in 2016, around 85% of students in lower secondary education were enrolled in public institutions. Among all OECD and partner countries, only Belgium, Chile and the United Kingdom have more than 50% of students enrolled at this level in private institutions, which include a large percentage of students enrolled in government-dependent private institutions. At upper secondary level, the share of enrolment in public institutions drops to 80% on average across OECD countries, with a decrease by over 20 percentage points in Iceland, Japan and Korea, where private institutions play a more prominent role at this level.
