Sorry to break it to you but if you haven't figure this one out yet...
Not every student/parent/coworker is going to like you.
And if you get that "I'm going to run out the back door and never come back" feeling at the first sign of feedback...this was literally made for you.
Instead of asking questions about what you can do better (which isn't really that helpful anyways). Ask questions about them, we call this the Parent Engagement Optimization (PEO) Survey.
Then use that information to get them on your side!
