That really stinks! You're writing a big check to these people who are causing you to doubt what you know about your son and causing you to question whether you're a good parent. You can get that for free at a public school.
When my oldest was in 1st grade I was given some bad normative data for her standardized tests and told that she wasn't gifted. It threw me for a loop and made me question what I knew from the previous 6 years of being her mother. Luckily with help from this board, I figured out it was bad norms instead of me being delusional. It makes me angry to hear about other parents being treated this way and I hope you'll get some better answers from the school.
