The report uses administrative data from different registers in Portugal to evaluate the impact of the ATIVAR.PT internship programme, one of Portugal's active labour market policies (ALMPs). It finds that the programme had a positive impact on employment and earnings within the short-term horizon of this evaluation. The report makes recommendations for improving the effectiveness of the internship programme and strengthening the capacity of the authorities to conduct ALMP impact evaluations. This report on Portugal is the sixteenth in a series of country reports on policies to connect people with better jobs. It is prepared as part of the OECD's project with the European Commission to help countries improve the quality of administrative data collected and their use in the evaluation of the outcomes and effectiveness of ALMPs.
