There does not seem to me to be any disconnect between IQ and achievement scores. Both are perfectly OK scores. You seem to be worried about hitting a ' magic number '. Since the testing did not seem to indicate a problem, what really would be the point of retesting her? Is she having a specific issue that you are trying to address ? WHY do you want to skip the JRK? You could just keep her home another year and teach anything you like. Please do not worry about test-prepping a four year old!
