This study presents the results of a research project conducted in 2008 concerning the integration of university graduates in the labour market based on data of the Greek universities' career offices. The research was funded by a Horizontal Action developed in the framework of the 2nd Operational Programme for Education and Initial Vocational Training. Specifically, the project explores the degree and the quality of the graduates' integration in the labour market 5-7 years after graduation, their working experience, the characteristics of the transition process from university to labour marker, as well as the difficulties they faced by those that were unemployed during the time frame covered by the project. The target group comprises graduates of the classes of 1998, 1999 and 2000, from all Greek universities with the exemption of the Universities of Central Greece and the Peloponnese (est. 2004) that at the time had not produced any graduates yet. The Horizontal Action study presents research results - tabulated by sex and scientific field - based on secondary data analysis of the 17 studies conducted by the Career Offices operating in the Greek universities.
