Should you spend good money on testing your daughter who makes a game of avoiding giving the right answers on tests, blocking you from using that particular test again for at least a year? What makes you think that would go well, the way things stand? It would be far better to address the intentional non-performance issue first, starting with a series of heart-to-heart talks with her. She needs to fully understand that you can't get her more advanced work until she shows the school that she needs it, and that otherwise you won't be able to help her.
I second this. My DD9 knew the alphabet cold at 16 months and was reading fairly fluently (gr 2 level?) at 3 yrs, but after her FIRST DAY at preschool she came home pretending that she no longer knew how. She wrote the book on going underground, LOL
Our pediatrician warned us against testing either child (I also have a son) until their behavioural issues are addressed, for fear that the scores would be suppressed. I regret not having DD tested BEFORE preschool, because it wasn't until she made contact with age peers in a class that she realized she was different and started playing chameleon.
She's 9 now, has been accepted into the gifted math program because of her achievement (we have no WISC-IV results to submit). She still has big perfectionism issues so I have no plans to have her tested any time soon. We'll see how it goes... she may be one who decides for herself to get tested as an adult (like me).
For a high achieving, non-chameleon child I think testing is terrific. I also think that testing can reveal valuable info about learning disabilities and can get a child help. For some anxious, "underground" kids, though... I don't know.
The ok thing about testing, though, is that scores can be falsely suppressed, so if you did proceed and the results are lower than you expected, you can consider them inaccurate and protect the child from being "limited" by them. But as Iucounu said, if you don't suspect any LD, why would you spend the money?
Instead you might want to consider compiling portfolio material for advocacy purposes.
Good luck
