In 2016, enrolment rates among 15-16 year-olds (i.e. those typically in upper secondary programmes) reached at least 95% on average across the OECD. At age 17, 92% of individuals are enrolled in education on average across the OECD, reaching 99% or more in Ireland, and Sweden, but also in partner countries Lithuania and Saudi Arabia. By contrast, fewer than 80% of 17-year-olds are enrolled in education in Brazil, Costa Rica, Indonesia, Mexico and Turkey, with the lowest rate in Colombia (52%). Declines in enrolment for this age group coincide with the end of upper secondary education.
