Looking for some general advice, for those who have needed to gain access to a sample population. How did you convince the gatekeepers of the benefits of your research, did you use tools such as powerpoint or just talk them through it. if so how did you structure your talk.

I've sent a letter and now have to go for a meeting to explain the impact of my research and how it will impact and benefit my sample population. I'm really struggling with this so any help appreciated.

Thanks:)

I would add that it is social research with young people
