My son sounds a lot like Tammiane's daughter or Trinity's son. Michael could memorize anything and was an early talker and reader. Since he was our first we chalked it up to just being advanced. At the end of first grade, when he was pleading every day not to go to school, but stay home and read, we finally decided to get him tested. Several doctors, pyschologists, grandparents, and teachers had suggested it before, but my husband and I didn't want a number associated with him. Finally one PhD said "Just test him and then you'll know exactly what you are working with". We ran the full battery of tests, 3 days worth, and it was eye-opening for my husband and me. Finally we knew where his strengths and weaknesses were, and got a good sense of HOW bored he was in school. His school let him skip 2nd grade and this year in 3rd has been great. He is not the ideal student, because he still wants to do what he wants, which is read all the time, but he has made friends and gets through the assignments he doesn't want to do. Could he have skipped another grade? Sure, but I think his particular class is really good for him, they have been very accepting and his teacher skipped a grade in grade school and really "gets" him and lets him do certain things at his own pace. He also happens to be very tall, and physically is probably the tallest kid in his class now, even though is 2 to 3 years younger than most other kids. I think looking at size is a big consideration because that is one thing the kids can't really pick on him about, and lots of kids in his old grade still give him a hard time about skipping.
All in all, I would definitely do a complete evaluation with a pyschologist for your kid. It can't hurt and would give you some valuable information about your child. We didn't even tell Michael what was going on. We just told him "You know how you can read and spell really well? Well, there are some people who want to figure out how your brain lets you do that. So you are going to see Dr. So and So and they are going to ask you questions and see if they can figure it out. You will be helping them." He has never been told his IQ or how well he did on the tests, and I am not sure if we will share that info anytime soon.
