At 3.0y Mr W had a teacher like that.
When she tested him, she stopped at the age level and did not keep going on the entire test through age five, which he knew all. We pointed out that he knew everything on the list. She did not even say anything to that.
Later she said he would not sit and "do his work." A 10 piece puzzle which he had mastered at 7 months was supposed to keep a kid occupied who could do 100 piece puzzles? When I asked did she think he was bored, she quickly said, "No."
Excuse me?
If this woman did not listen to us, we who pay her salary, or notice the specific content of our words, then she surely would not notice or care about a precocious little boy, which she obviously didn't.
Either she was an idiot, or she had malice towards him. Not sure which.
We moved Mr W shortly afterwards to a place that had a solid curriculum where he was accelerated into a class with kids 1-2 years older than he.
"Dad, the kids can talk!" was his first response when I picked him up on his first day.
