United World College in Mostar (UWC Mostar) was founded in 2006 as the core part of the Foundation Education in Action. It is one of the 15 colleges within the UWC movement.

UWC Mostar is the first UWC in the Balkans and the only one with an explicit aim to contribute to the reconstruction of a post-conflict society. The college educates students to learn and appreciate their differences, while promoting equality, tolerance, and critical thinking.

UWC Mostar students come from all over the world, as well as from all ethnic groups in Bosnia and Herzegovina and the region. All students live, study and serve in the community together creating a unique example of integrated education in post-war Bosnia and Herzegovina. The College also serves as the Centre for Professional Development of BiH Teachers who receive training in international educational standards.

UWC Mostar is accredited by Penta International - one of the leading independent providers of educational training, consultancy and inspection services in the United Kingdom and overseas.
