Being able to spell aloud but not in writing is also something I see in my son who is 9 and has stealth dyslexia. He makes similar spelling mistakes, for example, "bule" for "blue." High reading comprehension does NOT mean no dyslexia. Look online at some of he Eide's stuff online. Typical stealth dyslexia profile on reading tests is extremely high comprehension, with lower speed and accuracy. Many testers are familiar with stealth dyslexia.
