A portfolio is an organised collection of materials that presents and verifies skills and knowledge acquired through experience. It is of particular relevance to validating non‑formal and informal learning because it allows the individual candidate to contribute actively to the collection of evidence and also offers a mix of approaches strengthening the overall validity of the process. This is confirmed by the fact that many           countries have introduced the portfolio  as a central element in their validation approaches (CEDEFOP, 2009)

The Migrapass portfolio aims to identify and value professional experience acquire in their native country (often ignored in the host countries), the non formal and informal learning (such as a voluntary involvement for instance in migrants shelter) but also to value the unique competence linked to the expatriation  (leaving a native country, living and working in a foreign country). The professional profile of migrant publis is so enriched by unique competences most required on a changing labour market where abilities to adapt and mobility are key assets in a professional career.
