Part of this is making sure that all mentors are on the same page when it comes to conduct. FIRST’s YPP guidelines are a good start, but they are certainly not enough. I highly encourage teams to have their own Mentor Code of Conduct - rules, guidelines, whatever you want to call it - that’s public and visible to others. Even if you’re a school team, setting expectations for mentorship (and the various processes of reporting issues) inside your organization makes a difference.
Mentor culture is important. One of my goals each year in starting the school year is making sure the students know what ‘a good mentor’ looks like -one who follows our team’s code of conduct. I want to make sure they understand all adults on our team are primarily there for safety and support, and who to go to if they feel uncomfortable in a mentor interaction.
Editing to add - @Michael_Corsetto thank you for the reminder! We’ll be posting ours as well in the near future (once I get it cleaned up for some 2021+ changes.) I know how our student handbook has helped others, so maybe the mentor one will too
