This article is the second in a series addressing comprehensive suicide prevention programming in the school context. In this article, the authors discuss the importance of the student voice and the value of data collection in the development of this type of crisis prevention, intervention, and postvention. In the articles that follow this one, the authors will attempt to provide a reference to the programs that have been included in the evidence base in order to make it easy for school-based practitioners to engage with these potentially life-saving efforts, particularly as many practicing school psychologists may have limited access to the literature (e.g., databases behind paywalls vs. open-sourced materials).
