I would be curious to hear everyone's reaction to this part of the FAQ:

"Sometimes the Ruf Estimates indicate a lower result than previous testing indicated. There are three possible explanations for this:

* The parent couldn�t fill in enough of the questions on the Ruf Estimates form to make it possible to estimate the child�s relative intelligence, strengths and weaknesses. Remember, it is important to have good records or a reasonably good memory of your child�s early interests, behaviors and milestones in order to make the Ruf Estimates effective for you.
* On very rare occasion an assessment professional will score children too high. In my experience, you will find a surprising number of parents who report exceptionally high scores for their children and it will trace back to a particular assessment professional. This is very rare but it does occasionally occur.
* Most test companies, such as Riverside Publishing and Counseling Psychology Press, recommend waiting at least six months between testing sessions for the same child so as to rule out "practice effects." Very bright children should wait at least one year, however, because their memories are so good. Finally, some gifted children remember too much even when more than a year has passed, and the resulting higher score will not indicate a more valid assessment for that child."
