Lessons learnt from past accidents emphasize that major crisis management's limitations are mainly characterised by collective failures (organizational, behavioural and cognitive), absence and/or maladaptive training of actors (Guarnieri et al., 2015; Heiderich, 2010; Lagadec, 2012). Indeed, the training exercises have limitations such as the assessment: it focuses on the technical skills of the group, not on non-technical skills mobilized, and it is not conducted in real time. The presentation of the results during the debriefing is also incomplete (Tena-Chollet, 2012). The present work aims to present our method to assess trainees during crisis management training and feedback them, the EVADE (EVAluation and Debriefing) method. This method required the upstream creation of a typology of training objectives to be integrated into training and the identification of technical and non-technical skills of a crisis cell. The approach is based on behavioural markers which are used to identify mobilized skills of a group during exercise. The assessment tool is presented, through its construction and its functioning, and it is tested with trainees in crisis management exercises. Various examples of the results of restitution are then proposed in this paper.
