Labour market perspectives are positive compared to most OECD countries: unemployment rates are among the lowest across OECD and the proportion of 15-29 year-olds who are neither employed nor in education or training (NEET) is below average. In recent years, school leaders have benefited from increasing autonomy and their use of instructional leadership approaches is above the OECD average, according to school principals' reports in PISA 2012. Teacher training takes between 5.5 and 6.5 years, and the teaching workforce is ageing. Teachers’ salaries are among the highest across OECD countries.
