This article discusses postvention following suicide in secondary schools. It presents a strategic analysis assessing the relevance of a specific postvention program, the validity of the proposed interventions and the underlying theory. As a starting point, we describe the steps leading to the development of the program, the program itself and the assessment strategy that was chosen. In an analysis of the program, 49 experts in suicidology showed their appreciation of this program while suggesting some improvements, notably in intervention by professionals, factors targeted to reduce the effects of suicide and the justification for applying postvention measures.
