As a professional evaluator, I would far rather see the parents' honest impressions of their child than anything else. Your observations are part of the assessment data, and therefore need to be as accurate as possible. No one's asking you to estimate his intelligence or academic skills (that's what the testing is for)--just what you see and feel about your child. If preconceived expectations could change the results, then there would be no point in formal testing (or you would need a different evaluator, anyway!). The test data won't change because of your impressions, but the tester's selection of assessment instruments may, and you really don't want something with too low of a ceiling for a suspected GT learner. Please don't downplay your observations because you feel like you're bragging!
