The best Gauntlet volunteers are mature Christians, like the ones Paul describes in 1 Timothy 3:1-7. In addition, you'll want to have a genuine desire to invest in students. Because you will spend a lot of time, as in all of your time, with students.
Other qualities we look for in group leaders: someone who isn't easily flustered, someone who will communicate well with students' parents, someone who will be flexible when plans change and decisive when students are at a stalemate.
Finally, great group leaders know it's a big deal for parents to trust us with their students. They don't take that responsibility lightly, and they work hard to make sure students have fun and stay safe.
