Most 25-64 year-olds in Germany (55%) have attained a vocational qualification at either upper secondary or post-secondary level, the fourth largest proportion among countries with available data (the OECD average is 33%). Due to the high incidence of vocational qualifications, and the fact that a general degree (mostly Abitur) is dedicated to further education and not to direct entry in the labour market, only 3% of adults attain a general upper secondary or post-secondary qualification as highest degree, one of the smallest proportions among OECD countries (the OECD average is 12%) (Table Al. Between 2005 and 2012, unemployment rates decreased by 7 percentage points among adults without upper secondary education (from 20.1% to 12.8%), by 6 percentage points among those with an upper secondary or post-secondary non-tertiary education (from 11.0% to 5.3%), and by 3 percentage points among those with a tertiary qualification (from 5.6% to 2.4%).
