We did not do any type of test preparation the last time. I know they say that IQ tends to stay within about a 10 point variance and I was wondering if that was accurate based on actual experience. Has anyone retested who can share their experience?
My dd9 retested on the WISC-IV one year after her first test and came out 20 points lower. Her first score was very high, though with a 99.7th percentile on verbal and 99th on PRI. She is a very erratic child, though, and I'm not sure that either score is a true representation of her. I'm assuming that she is gifted at this point b/c both GAIs were gifted, but how gifted, I really don't know.
