In most OECD and partner countries, boys are at least 40% more likely than girls to enrol in vocational education (Figure 2.a), and students whose parents did not attain tertiary education are more likely to choose upper secondary vocational programmes than general programmes (Box B3.1). By including formal and non-formal education, this indicator captures participation in any type of programme that aims to improve knowledge, skills and competencies from a personal, civic, social or employment-related perspective (UNESCO, 2016(2]). In most OECD and partner countries, at least 20% of 25-64 year-olds have participated in formal or non-formal education and training in the previous 12 months, with participation among men and women varying greatly across countries.
