It can definitely be tricky. I'm now a teacher for Outschool and sometimes the conversations with parents can be tricky. I have tween parents trying to put their children into my teen writing group. They don't realize sometimes that the levels aren't about grammar and spelling - both groups are quite good at those things. It's about the intensity of the issues - sometimes sexual - that the older group is addressing. There are just some things that the younger students aren't ready for emotionally.
