No definitive information - just my experiences and what I have read.....
The guy who tested my son was used to LD kids and even so, we feel he did a good job on him. Maybe not all we could have gotten from the test had someone else done it- but he was used to not-average and stayed very aware.
If you got the detailed report, you can look at the scaled scores on the subtests and see if there are any 19s. That equates to hitting the ceiling on the test.
I read somewhere that you should wait 2 years before using the same instrument. I always ask the question: what will be done differently based on the score?
Curiosity is a powerful thing - but not necessarily a good reason to retest IQ.
I recently took my son for a complete evaluation by a pediatric neuropsychologist. I expected a new IQ test and she didn't do one. She said there was nothing we could get from it that would be as actionable as the individual achievement test - so she did that instead. (His IQ scores were only 1 year 4 months old).
If you really want more information, you might think seriously about individual achievement testing. They are normed similar to the IQ scores and can be very useful. Make sure that they can also give you the grade level scores and age level scores. That will allow easier communication with the school as they are more likely to understand what grade 5.7 means than what 145 on math means.
Where are you located? hoagiesgifted.com has a listing of psychologists that people have written in to recommend as having been good with their gifted child. You might find someone within driving distance that way.
As I mentioned, we did just do a full evaluation on our son (except for IQ) with a specialist in gifted kids and we found it very worthwhile - including a report with recommendations on grade placement and accomodations. She found several areas of weakness that everyone else had overlooked and we are going to start working with an occupational therapist and have his hearing tested based on her recommendations.
I would suggest seeing if the school can't do something with compacting. Compacting combined with distance learning might actually be more useful in some ways than a typical gifted program. Some gifted programs just mean the child gets more work than other kids.
Good luck,
Mary
