Not to take anything away from this child's accomplishment, as achieving the top score possible is rare.

However I'm somewhat wary of this particular test as there appear to be online versions which one can use for training, thereby inflating their score on a subsequent test administration.

Additionally the news reporting could provide more context. For example, IQ scores vary between tests, therefore her 162 on a child-level test does not necessarily exceed the IQ of Stephen Hawking and Albert Einstein, as claimed. It's an apples-and-oranges comparison.

This article announcing a different child achieving the top score seems a bit more balanced, lists other recent test-takers with the same score, and provides a bit more context.
