You have met your first micromanager. She won't be your last.
I would suggest, TACTFULLY, speaking to one of the program managers about her. Something like... "Hey, Fred... Betty just gave me a lot of suggestions about dealing with the high school students. I was just wondering if there's anything specific we're required to do with them or what." (Make up your own; I don't know enough to give you a good one.)
If you're lucky, a straight line like this will result in one of two responses and give you a good idea of how to proceed:
- Oh, yeah, that Betty is great... I tell ya, we couldn't run this program without her
- Yeah, she's really a pain in the ass isn't she? We have to humor her, but don't worry about all the stuff she tells you.
