The Gatekeeper Training Implementation Support System (GTISS) provides a framework for planning, organizing, and implementing suicide prevention training in any system, organization, or community context. The system provides tools and resources to help gatekeepers adopt what they learn in training and use it to help youth and adults of all ages. These tools can be adapted for any context and population, including the juvenile justice system, education, child welfare, and beyond. The GTISS has five stages – Preparation, Training, Translation, Application, and Reflection. Each stage has a slide show describing its goals, actions, research support, and tools.
