Hello!
This is my first post. I bet you'll never guess what sorority my daughter joined
I am an elementary teacher of the gifted and when I get the old "Hey, my kid is the best thing since sliced bread AND he's gifted...." I show how the test/assignment fits in with the learning goals of your program. Let the parent know what your goals are for their child and what can be done if the little darling is falling short. As a parent, that is all you can really ask for. Sometimes parents come across as frustrated because they are just really anxious about helping their child succeed.
