I’m not an expert, but no, I don’t think so. I think IQ tests are normalized, (set so they have the same mean and standard deviation), but the distribution could still be non-normal. Of course, the tests are controlled by many small factors (questions) which perhaps gives another reason for why the observed distribution would be normal.
