Apparently our schools Terra Nova test scores were all entered incorrectly. All the children we entered with the birth year of 2000. That reflected my son being 2 years older than he actually is. How much does this affect his IQ score? He scored in the 99th percintile of every subject, but only showed an IQ score of 108 -- I was told it should come back much higher... but will it be high enough to still be considered "gifted"?
