Figure 6.4 shows that Korea’s ratio of public education expenditure to GDP is higher than the OECD average of about 5% of GDP. Historically, education expenditures have been very stable, at around 16-20% of total government expenditure, with limited variation due to strong government support for national growth. This stability indicates Korea’s strong commitment to education. Most of the remaining government functions show a different trend, which is inconsistent and volatile due to the change of social needs and of policy priorities, along with economic and social development.
