Select any major mental health-related, crisis work/crisis relief organization of your choice, and then learn all you can about that organization. This research can be conducted by studying their corporate website, finding marketing or general information documents, doing a phone interview with the director of the organization, etc. You will need to have a good understanding of the general purpose, function, and requirements of the organization you choose.
Examples of research/interview topics include: the role of first responders at the organization, qualification criteria to work/volunteer there, types of training they offer, first responder skills implemented at this organization, etc. To have a good context for your findings, you will also want to ask basic demographic information about the organization, such as the population they serve, where they are located, and their mission statement.
Your chosen organization must be situated in your local community or county/region. Exceptions to this requirement will be rare and only given on a case-by-case basis.
