Yes, there is lots of info on Ruf. I actually just started this thread to hear personal experiences regarding whether you chid's IQ corresponded with Ruf scores. I know it doesn't always, just wanted to see what others had found.
Ruf�s book came out after our son had taken the SB-4 and WIAT. He had already qualified for Davidson based on his scores, our descriptions of his pursuits, interests and intensities, as well as, two letters of recommendation from his school staff. As example, in the letter his assistant principle submitted (and gave me a courtesy copy), she described a particular exchange between them illustrating his initiative, highly developed reasoning, concern for justice and precise, advanced vocabulary.
In reading �Losing our Minds� and looking at the milestone ages, I could determine that my daughter�s development fit at level 4 (met ~ 75% of list) and my son fit at 4+ (met several level 5 benchmarks, but fewer than level 4). My daughter had previously achieved 99.6% on the WISC-III and my son was already a YSer, so I would say these different measures yielded consistent results. In our case, the IQ tests were first.
