I agree with this.

I also agree with this:

Also, if a false claim of giftedness is made in real life, it can make teachers cynical when an actual HG+ kid comes along. How many of us have had to convince teachers that our kids really are gifted in the face of a belief that parents make it up? That belief isn't formed in a vacuum.

One can't confirm everything with a test, but in the case of IQ, it's possible.

There's also confirmation bias (a tendency to seek or interpret information so as to confirm a belief while ignoring evidence to the contrary). So that's a problem and leads us back to the need for an objective measure (e.g. an IQ test administered by a competent professional who doesn't know the child and has no stake in the score).
