The first training school was held  from 15-17 April 2015 in Split, Croatia on "Skin barrier assessment in occupational dermatology". The event was hosted by Ivone Jakasa, University of Zagreb, Faculty of Food Technology and Biotechnology.

In total, 27 trainees from 10 countries attended the training school at the premises of the Mediterranean Institute for Life Sciences (MEDILS). The feedback received from the students was very positive as the agenda entailed a good mixture of plenaries and practical work in small groups. 

The most recent and performing technology was presented by two companies during the course (Raman Confocal Microscopy and Atomic Force Microscopy). This was a unique opportunity for all students to get acquainted with this technology, which worldwide is currently only being applied in 35 research centres. The students presented the results of the practicals at the end of the training school.
