It is a trainee exchange programme that enables law students and young lawyers to gain first hand experience of the substantive and procedural law as well as the culture of another country. The traineeships are between 2 weeks and 18 months and can take place in any law related area; law firms, courts, public institutions, banks, in-house legal departments, consulting firms and international organisations.

Before and during the traineeship, ELSA provides assistance with finding accommodation, applying for visas, when necessary, and organising social events to involve the trainee in the daily life of the local community.
