Unemployment rates among Portuguese adult population have been rising even before the present crisis, a feature that distinguishes Portugal from most labor markets of EU-21 or OECD countries. Furthermore Portuguese adult population is also enduring increasing long term unemployment. Efforts to upgrade educational attainment did not succeed in changing the trend. The unemployment differential between higher education graduates and those with less than upper secondary is well below the corresponding average value for EU-21 or OECD. Therefore, we aim to assess how much formal, non-formal and informal learning contribute to enhancing employment and reemployment opportunities.
